Abstract

A method of applying a protective coating to an article comprises the steps of applying to said article a coating of a polyolefin, applying to said coating a layer of glass cloth or sheet plastics material and applying to said glass cloth or sheet plastics material a surface coating. The polyolefin, in the form of an amorphous polypropylene or an atactic polypropylene, will be applied to a thickness of the order of 4 mm, and the surface coating will be one or more layers of polyurethane paint.

Description

SPECIFICATION Coating process This invention relates to a method of applying a protective coating to an article.
According to the present invention there is provided a method of applying a protective coating to an article comprising the steps of applying to said article a coating of a polyolefin, applying to said coating a layer of glass cloth or sheet plastics material and applying to said glass cloth or sheet plastics material a surface coating.
The method may include the additional step of applying a second layer of said polyolefin prior to the application of said glass cloth or sheet plastics material, and said method may include the additional step of applying a second layer of glass cloth or sheet plastics material prior to the application of said surface coating.
The method may include the step of preparing said article prior to the application of said coating of polyolefin, and applying one or more coats of paint and/or primer prior to the application of said coating of polyolefin.
Said polyolefin will preferably be an amorphous polypropylene or an atactic polypropylene, and the glass fibre will preferably be in the form of a mesh.
In order that the invention may be more readily understood, an embodiment thereof will now be described, by way of example, reference being made to the accompanying drawings, wherein Figure 1 illustrates the method according to the invention; and Figure 2 is a cross-section of part of the hull of a boat which has been given a protective coating in accordance with the invention.
Referring to the drawings, and firstly to Figure 1, an article or structure 2 to be coated or sheathed according to the invention is provided with a prepared surface 4 (for example one or more coatings of paint and/or primer), to which is applied a first layer 6 of amorphous polypropylene.
The amorphous polypropylene may include one or more resins such as those sold under the name ESCOREZ in order to improve the adhesion factor.
Said first layer of amorphous polypropylene has a thickness of the order of 0.125 inches (approx.
4 mm). To this first layer is applied a second layer 8 of amorphous polypropylene having a thickness of the order of 0.0625 inches (approx. 2 mm) to 0.125 inches (approx. 4 mm). Again, the amorphous polypropylene may include one or more resins.
Prior to application, the amorphous polypropylene is heated to a temperature of about 1 400C so as to make the material workable.
To the second layer 8 of amorphous polypropylene, which is applied at a temperature in the region of approximately 900 C, is applied a fine finishing glass cloth 10, the glass cloth being applied with the aid of heated tools, not shown.
The glass cloth is smoothed in with a heated tool (not shown) so as to give a reasonably even surface.
Instead of using glass cloth, sheet plastics material may be used, or the sheet plastics material may be used in addition to and in combination with the glass cloth.
Finally, one or more coatings 1 2 of paint preferably polyurethane paint - or varnish is applied to the surface after the amorphous polypropylene has been allowed to cool. The complete "laminated" coating is indicated by reference numeral 14.
The entire surface or surfaces of an article may be coated according to the invention, or merely a part or parts of said surface.
The invention is particularly although not exclusively suitable for the protection of the hulls of boats or ships, where a water-resistant and waterproof coating is required. Reference to Figure 2 shows a cross-section through part of a hull 1 6 of a boat. A probable water line is indicated by reference numeral 18. To the hull, that is to the whole of the underside of the hull and finishing at a predetermined distance above said water line 18, there is applied a "laminated" coating 14 formed in accordance with the above description. Such coating fully protects the hull 1 6 from the effects of water and particularly from sea water.
If desired, the inner surface 1 6A of the hull 16 may similarly have a "laminated" coating applied thereto, such that the whole of the hull lying below the water line 1 8 is fully coated or "sheathed" in accordance with the invention.
With a sheathing or coating system according to the invention, an article or structure is fully protected from the effects of water and other deterioration inhibiting factors, and should reduce the maintenance of the coated or sheathed surface(s) to a minimum.
1. A method of applying a protective coating to an article comprising the steps of applying to said article a coating of a polyolefin, applying to said coating a layer of glass cloth or sheet plastics material and applying to said glass cloth or sheet plastics material a surface coating.
2. A method according to Claim 1, including the additional step of applying a second layer of a polyolefin prior to the application of said glass cloth or sheet plastics material.
3. A method according to Claim 2, including the additional step of applying a second layer of glass cloth or sheet plastics material prior to the application of said surface coating.
4. A method according to any of Claims 1 to 3, including the step of preparing said article prior to the application of said coating of polyolefin.
5. A method according to Claim 4, including the step of applying one or more coats of paint and/or primer prior to the application of said coating of polyolefin.
6. A method according to any of Claims 1 to 5, wherein said polyolefin is an amorphous polypropylene or an atactic polypropylene.
7. A method according to Claim 6, wherein said amorphous polypropylene or atactic polypropylene
