Description
2(~u36;~S
This invention relates to a wood treating and coating composition affording improved durability, water-repellence and aesthetic appearance. The coating composition permits treatment of wood with preservation of the natural grain appearance, when colored, while protecting against the effects of the elements.
A large number of stains or coatings is currently ~ -~
available for the treatment of dressed lumber and ~inished wood for external and internal applications, including acrylic coatings, latex coatings, lacquer, lacquer cellulose, epoxy resin, so-called liquid plastic, varnish ~
resin, and numerous oil-pigmented stains. All such ;~; n-products suffer from some drawbacks and limitations (especially when used outdoors), such as limited durability, undue opacity, dullness of finished surface, deterioration of aesthetic appearanoe in a relatively short period of time, lack of breathability, cracking, evaporation and flaking, light-degradability, shrinkage and ~-unsuitability for external use, leading to the need for periodic re-application or replacement.
Shellac has been employed for many years as a wood caatling sub~s,ta~ce ,or~ as a component in coating compositions. For example, Canadian Patent No. 1346 describes a composition for mixing with paint and co~prising water, shellac, washing soda and linseed oil.
Patent No. 13935 discloses a paint composition containing resin, shellac, camphor, castor oil and glycerin. Patent No. 16492 describes a coating composition containing ~: :
200:~3~
-shellac, beeswax, whiting and alcohol, while Patent No.
53510 describes a paint composition containing methyl alcohol, shellac, pine resin, camphor and gum arabic.
Patent No. 60431 describes a paint containing shellac, methylated spirits, pigment and varnish.
Moreover, Canadian Patent No. 217,435 discloses a wood filler composition comprising beeswax, paraffin wax, turpentine, linseed oil, varnish, Japan drier and shellac.
Finally, Patent No. 510,480 describes a staining and filling coating composition for wood containing a solvent mixture of butanol, shellac, ethanol, manilla gum, silica, talc, neutral stain filler, dye, ethyleneglycol ether and thinner.
Shellac alone as a coating material would dry too fast and modification of the drying characteristics of shellac might impair the coating qualities thereof.
It is accordingly an object of the present invention to provide a wood coating composition which avoids or mitigates the disadvantages and shortcomings of currently available products and which affords an improved coating providing durability, breathability, water-repellence and attractlivle ! aesthetic appearance, while retaining sufficient transparency to permit visibility of the natural grain structure of the wood.
It is a further object of the invention to provide a wood treating and coating composition which is compatible with existing wood preservative compositions and which, furthermore, can be pigmented or dye colored.
;: :- ,.,: ,:
~ ,, .:
Accordingly, one aspect of the invention provides a wood coating composition, which comprises: (a) ~rom 5 to 20 lbs of a raw or refined shellac, (b) from 1 to 3 gallons of a nut tree oil, preferably selected from castor oil, tung oil, cashew nut oil, china nut oil, pine oil, and mixtures thereof, (c) from 0.5 to 1.5 gallons of a drier, preferably selected from Japan drier, cobalt naphthenate drier and monosec drier, (d) from 0.05 to 2, preferably 0.5 to 1.5 gallons of a glycol, preferably ethylene glycol, and (e) a balance of an alcohol, such as methanol, ethanol, isopropanol `or butanol or mixtures thereof or methyl hydrate.
If desired, the composition can further incorporate an alcohol-based stain or ink, a dye, a pigment, a preservative and/or an anti-fungicide.
A further aspect of the invention provides a water-based wood coating and treating composition, comprising a formulation as defined above in association with an emulsifier, which composition can be diluted with a desired volume of water.
Another aspect of the invention provides a process for formulating .a water-based preservative composition for treating wood which comprises: (i) mixing together the above specified ingredients (a) to (e) in amounts falling within the ranges specified, (ii) thereafter adding the emulsifier and the water, (iii) allowing the resultant water-based composition to stand for a sufficient period of time, and (iv) admixing the water-.~-; . .`
based composition with a wood preservative, such as an aqueous solution of copper chromite and copper arsenite.
The coating composition of the invention preferably contains about 10 pounds of raw or refined shellac dissolved in about 3 gallons of methyl alcohol, about 2 gallons of castor oil, about 0.5 gallon of monosec drier or cobalt naphthenate drier, about 0.5 gallon of ethylene glycol, about 1 gallon of alcohol-based stain and, additionally, about 2 to 3 gallons of the alcohol.
Preferred alcohol components include methanol alone, and mixtures of methanol/ethanol, methanol/isopropanol and methanol/butanol, for instance in 60/40 ratio by volume percent. Another preferred alcohol mixture is butanol/ethanol/isopropanol of 60/20/20 parts by volume.
In the composition of the invention, the properti~s of the shellac are modified by the remaining ingredients, so as to permit exterior use of the ¢omposition primarily on wood and wood products, but also on brick, cement, metal and fiberglass. This is achieved partly by the use of a larger than usual proportion of the drier, which functions to harden the finish. The presence of the nut tree o~ assists in absorption of the shellac into the wood and improves the sheen of the finished wood product. It further improves the body of the liquid , ~ - - :
25 composition which assists in application thereof and - ~
, affords improved elasticity, strength and durability to the -~
shellac when compounded with the dryers. The nut oil inhibits the degree of drying of the finish so that, ~ ~
. ~ ,.~. ,;; , although the coating feels dry to the touch, it never dries completely hard but retains elasticity for expansion and contraction due to temperature change of the coated substrate.
The function of the glycol, such as ethylene glycol, is to assist in the admixture of the shellac, drier and nut tree oil and further acts as a fire retardant. It should also be noted that shellac itself is a generally non-flammable substance. Moreover, the presence of ethylene glycol assists spreadability when the composition is pigmented or dyed and blends the dye or stain so that it does not separate from the composition or cause streaking, thereby giving rise to a coating which is uniform in color.
The alcohol functions as a solvent for the shellac and, further, as a thinner for the overall composition. A preferred drier is Japan drier, which is a varnish containing a large percentage of resins and driers used as a liquid drier for paints and coating compositions.
The amount of Japan drier in the composition of the invention is relatively larger than has been used conventionally, which assists in modification of the properties of the, nut qil and shellac and results in an improved sheen, water-repellence and aesthetic appearance of the coatings.
The composition of the invention can also include a non-toxic preservative, pesticide or fungicide, such as oxine copper, as well as a stain or pigment permitting a final composition affording a wide range of wood-simulating :~ . ' ~''`''`
20036;~5 .~.. , :
6 ;~
or other colours, while remaining a completely non-toxic, preservative coating.
The coatings obtained employing the composition of the invention are not only water-repellant but also water-proof, while permitting breathability of the underlying wood. They are therefore of particular use in applications near water, such as pool patio decks, boat decks and any location in which show wood is located near water. The extremely tough properties of the resultant coatings are ideal for walking areas, such as decks and patios, and present a durable, smooth, water-proof surface.
However, the composition can be employed equally well for interior applications, such as interior mall show wood, wood panelling and unfinished furniture.
15A particularly advantageous embodiment of the invention relates to the conversion of the composition of -the invention into a water-based form, which is compatible with existing wood preservative compositions containing copper chromite/copper arsenite (CCA). The conversion is achieved by adding to the composition of the invention a suitable quantity of an emulsifier, e.g. from 0.1 to 10% by ~: .... i :..
volume~ more preferably!from 0.5 to 5% by volume. Suitable emulsifiers include alkanolamines, preferably triethanolamine. Thereafter a suitable quantity of water is added and the resultant formulation is mixed with a water-, ~ :
based CCA-containing formulation. It is important for the mixture of the composition of the invention and emulsifier and water to stand for a period of time, for instance about .
24 hours or more prior to admixture with the CCA-containing solution.
The resultant formulation can also include a pigment or dye, which can be present in sufficient concentration to result in masking of the characteristic blue-green colour of CCA-containing products, so that the final pressurized coating on wood can be obtained in any desired colour and provide a durable, attractive and preservative finish to the wood. Treatment of wood in this manner can be carried out, for instance, in the pressure treating lumber plant in advance of sale when used in conjunction with CCA pressure treatment or other pressure treatment formulae, or can be applied to a finished wood structure or product.
Thus, in essence, the composition of the invention employs shellac, which is a completely non~
durable and generally unacceptable material for exterior wood use, and which has been modified and formulated together with the remaining ingredients to produce a composition providing extremely affordable exterior wood coatings fully impervious to the elements, when not converted to ai ,water-based form. In summary, !the composition of the invention seals and water-proofs wood, permits stain-finishing in different colours or a clear, natural finish, and is transparent even with dye color added, or semi-transparent when pigmented, thereby ; permitting the wood grain to show, is more durable and lasts longer than existing exterior coatings, does not . ~003635 , . , darken when re-coated unlike other outside coatings and stains, affords a significant degree of fire retardancy, is non-toxic and environmentally safe in being formulated primarily from organic materials, and can be converted to a water-based form which provides a medium for colour and sealer and which can be employed in conjunction with currently available pressure-treating preservatives, such as CCA, to produce an aesthetic, preservative, coloured finish in pressurized wood.
The following Examples illustrates the invention.
10 pounds of shellac flakes were dissolved in from 1 to 2 gallons of methyl alcohol and 2 to 4 quarts of triethanolamine was mixed in with vigorous stirring. 2 gallons of castor oil, 2 quarts of cobalt naphthenate drier (monosec) and from 2 to 3 quarts of ethylene glycol and 1 to 2 quarts of butyl glycol (Cellosolve) were added with - vigorous mixing. If desired, an alcohol solvent, tinting stain, alcohol aniline stain, ink stain or dye stain can be added to provide a desired degree of colouring.
This formulation can be used for wood treating ~and coating. The triethanolamine emulsifier can be replaced by monoethanolamine or a mixture of equal parts of triethanolamine and butyl glycol. The methyl alcohol can b- replaced by similar amounts of ethanol, isopropanol, butanol or amyl alcohol or mixtures of some or all thereof.

A water based wood coating composition was prepared by dissolving lO lbs of shellac flakes in the minimum sufficient amount of methyl alcohol (approximately 1 to 2 gallons). From about 3 to 4 quarts of triethanolamine was mixed in which vigorous stirring and the mixture was allowed to stand. If desired, the triethanolamine can be partly or wholly replaced by monoethanolamine or partly replaced by butyl glycol. 2 gallons of castor oil, 2 quarts of cobalt naphthenate and 2 quarts of ethylene glycol were then admixed with vigorous stirring. The product is allowed to stand for a further 24 hours.
`From 5 to lO gallons of warm water are then added with vigorous stirring to provide a water-based composition. This composition can be mixed with a CCA-containing preservative composition prior to use, or CCA in an amount of about l to 5% by volume, preferably about 2 l/2~ by volume, can be added to the composition of this example to provide a wood coating and preserving formulation.

The composition of the invention when used in conjunction with a CCA-containing product acts as a water-soluble, oil medium for color to mix with the CCA and eliminates the harsh drying of the basic CCA-containing product, thereby reducing the risk of wood rot between pressure treating and drying in the lumber yard. The product will seal the pressure-treated wood when dry and provide water-repellency, thus eliminating the necessity of re-coating the pressure-treated wood with a water sealer. It further provides an aesthetic finished appearance to the lumber, as opposed to a dry look and can be provided with a range of colours, substantially eliminating the characteristic blue-green coloration of the CCA-containing product.
