Abstract

Combinations of nonvolatile reactive amines, and hydroxyl bearing, unsaturated esters and/or ethers and/or ether-esters (and/or combinations of non-hydroxyl bearing, unsaturated esters and/or ethers and/or ether-esters, and saturated hydroxyl bearing etherified and/or esterified oligomeric glycols and/or oligools), as replacements for conventionally employed volatile amines and/or ammonia as neutralizers, and organic solvents as coalescents respectively, has been found to enable the production of economical, low to no VOC acrylic and vinyl copolymer latex based coatings, paints, and inks. Further enhancement may be had by substitution of hypersurfactants, in place of conventional soaps and/or dispersants and/or detergents, in combination with the aforementioned nonvolatile reactive amines, particularly as particulate dispersants in pigmented and/or reinforced coatings.

Description

LOW ENVIRONMENTAL TOXICITY LATEX COATINGS Background of The Invention: The use of ammonia and/or volatile amines as neutralizing agents and/or stabilizers, and of alcohols, glycols, and glycol onoethers and monoesters, often in combination, at levels to 40% by volume (exclusive of water) has been employed for more than fifty years to achieve the coalescence of latex solids in acrylic, polyvinyl acetate and related copolymer resins based coatings. The volatilization of these conventional neutralizers, and coalescing components, after achieving film coalescence is normally required in order to inhibit the resultant film's breakdown (reversion) in the presence of humid environments, and to provide acceptable wear and stain resistance to the dried film. Recent concerns regarding the environmental degradation (predominantly low level ozone formation) , and the health and fire hazards associated with exposure to ammonia, volatile amines and volatile organics (VOCs), has led to increasingly strict regulatory limitations on the nature, and proportions, of VOCs which may be employed in coatings . One technique that has been employed in order to comply with said limitations in latex coating applications is the development of self coalescing latex resins which require no coalescents. However, to date, such materials have had the disadvantage of being limited to low Tg film formers with poor performance properties. Subject of The Invention: This invention teaches the use of low levels of combinations of nonvolatile reactive amines, in combination with hydroxyl 1 bearing unsaturated esters and/or ethers and/or ether-esters,
2 and/or non-hydroxyl bearing unsaturated esters and/or ethers
3 and/or ether-esters and incompletely etherified and/or esterified
4 oligomeric glycols and/or oligools as partial or full replacements
5 for conventionally employed volatile amines and/or ammonia as
6 neutralizers, and organic solvents as coalescents, respectively,
7 in latex resin applications. This invention has the advantage of
8 reducing emissions and enhancing the performance of films produced
9 from conventional latex resins, and when employed in conjunction
10 with certain types of hypersurfactants (cf. Table 5) also
11 upgrades pigment and/or extender dispersion, and reduces grind
12 times in particulate containing variants; thus enhancing plant and
13 energy use efficiencies. Synergistic performance enhancement, and
14 VOC reduction in latex resins may be attained via the employment
15 of the aforementioned technologies in combination. Partial
1.6 replacement of either or of both of the aforementioned components
17 by the alternatives of this invention is shown to provide lesser,
18 but still desirable benefits.
19 Preferred Embodiment of The Invention
20 The non-volatile reactive amines useful in the practice of
21 this invention have vapor pressures below 0.1 mm Hg at 25°C,

Further amplification of the scope and utility of the instant invention to latex coating applications in inks, paints and stains shall be found to be illustrated by the content (s) of examples 1 through 5. Said examples are intended to be illustrative rather than exhaustive of the extraordinarily diverse applicability of the instant invention. Example #1 This example teaches the superiority of the present invention versus the prior art with respect to the productivity, VOC emissions, and performance quality in a masonry sealer application. A masonry sealer formulation was prepared by the sequential dispersion of the indicated components (pigment dispersion times and grind quality achievement was noted) . The resulting sealer was applied via roller to smooth surface, ten day old, 8" X 18" X 1" thick concrete castings, at an application rate of one gallon per 400 square foot, dry time (to touch) was measured under conditions of 72° F and 85% humidity. After 240 hours of drying @ 72° F and 85% humidity, sealer performance was measured by weighing the dry casting, then impounding a 6" depth of water, or alternatively 6% salt solution, on such a casting for twenty four hours, then draining and weighing the drained casting. The weight percent of water, and independently that of 6% salt solution, adsorbed by said castings were used to determine sealer efficacy. The results of this study are given in Table No. 1.

The efficacy of the coalescent systems of the instant art in producing a more, scrub and stain resistant PVA latex based interior flat architectural coating as compared to a conventionally coalesced counterpart, Formulation No. 1, is obvious from the preceding data. VOC emissions reduction and improvement in both productivity and dispersion level achieved are likewise self evident, as is a considerable reduction in minimum coalescence temperature, without recourse to the use of low boiling, flammable solvent (s), normally employed to induce same. Example #4 This example teaches the superiority of the present invention versus the prior art with respect to the productivity, VOC emissions, and performance quality in a force dried, clear, protective, two component acrylic latex cured - waterborne epoxy, wood cabinet coating. Component A. neutralizing agent, as shown-3.5 PBW; sodium nitrite 0.15 and defoamer (Patcote 519-Patco Coatings Inc.) were admixed with 95.85 PBW of (Acrylic latex-Maincote AE 58) , and said emulsion was subsequently mixed with 50 PBW of Component B, formulated by blending various additives, as shown, into 12.5 PBW of Genepoxy 370-H55- Daubert Chemical Co., and diluting as necessary with water to produce a total part B weight of 25 parts. Thixatrope1, was added, as required, to provide an initial mix nonvolatile reactive amines, in combination with hydroxyl bearing unsaturated esters and/or ethers and/or ether-esters, and/or non- hydroxyl bearing unsaturated esters and/or ethers and/or ether- esters and incompletely etherified and/or esterified oligomeric glycols and/or oligools as (partial or full) replacements for conventionally employed volatile amines and/or ammonia as neutralizers, and organic solvents as coalescents, respectively may be employed to substantially enhance the processability (pot life) , mechanical and chemical resistance properties ( abrasion and stain resistance respectfully) as well as attain VOC reduction in wood coatings. A further benefit of the instant invention as applied to wood coatings is that unlike conventionally coalesced waterborne coatings, e.g. formulation D-l latex formulations based upon the teachings of this invention, e.g. formulations D-2 through D-7, do not cause significant grain rise, thereby virtually eliminating the necessity for intercoat sanding. These data also demonstrate that subsets of the preferred combination of components herein disclosed (e.g. formulations D-3,D-5, and D-6) may provide considerable benefits relative to their conventional counterparts, such as Formulation No. 1; however, omission of one or more of the components of the combination herein disclosed leads to inferior results as compared to the inclusion of the full compliment. Example #5 This example teaches the superiority of the present invention versus the prior art with respect to the productivity, VOC emissions, and performance quality in waterborne flexographic inks. A latex flexographic ink formulation, was prepared by the sequential dispersion of the indicated components (pigment dispersion times and grind quality achievement was noted) . The resulting ink was applied via a #6 wire wound rod to bond paper, and permitted to dry. Dry time (to touch) was measured under conditions, of 72° F and 85% humidity. After 6 hours of drying @, 72° F and 85% humidity, heat seal resistance performance (face to face) was measured at 25 psig. and 2 seconds contact time) the results of this study are given in Table No. 5.

Example #6 This example teaches the utility of the instant invention in the production of superior waterborne anti-scuff overprint coatings for graphic arts applications. A 30% solution of water reducible styrene-acrylic copolymer resin in water was prepared by admixture of the indicated neutralizing agent-as shown, water, and Air Product Corp's Flexbond 28 resin. Thirty parts by weight (PBW) of the preceding solution, were admixed with 50 PBW of styrene- acrylic latex resin (Flexbond 285, Air Products Corp.), coalescent, and surfactant (s) -as shown, poly ethylene wax, 2 PBW, and sufficient water to dilute the system to 100 PBW. The resulting coating was applied, in line on a high speed six color lithographic cold web press, to a solid four color print pattern, followed by in line infrared drying, and folding.
