Abstract
A solid-particulates-containing composition that can be available ready-made but with a substantial shelf life; in one form it can truly be applied like a conventional paint, and in another form in workable in the manner of a putty. With only a light polishing or burnishing it gives an excellent finish. More specifically, the solid-particulates-containing composition comprises 5-80% by volume of the chosen particulate solid dispersed within either a vinyl acetate polymer product or an acrylic polymer product (or one which is a mixture of the two, with, per 100 volume parts of vinyl acetate polymer product, 5-80 parts of acrylic polymer product), there being, per 100 volume parts of the chosen polymer, from 25 to 80 parts of water.
Claims18
A composition for applying as a coating to a surface to give a metallic or stone appearance to the surface, the composition comprising an aqueous dispersion of solid particles within a resinous carrier and comprising:
- a metal, or metal alloy or inorganic non-metal particulate solid;
- a particulate organic film-forming vinyl acetate polymer (or copolymer) having a Tg of below 10° C.;
- and
- a particulate organic film-forming acrylate polymer (or copolymer) having a Tg of above 30° C.
A composition for applying as a coating to a surface to give a metallic or stone appearance to the surface, the composition comprising an aqueous dispersion of solid particles within a resinous carrier and formed by mixing:
- a metal, or metal alloy or inorganic non-metal particulate solid;
- a first product containing particulate organic film-forming vinyl acetate polymer (or copolymer) and having a Tg of between 0° C. and 20° C.;
- and
- a second product containing a particulate organic film-forming acrylate polymer (or copolymer) and having a Tg of between 30° C. and 70° C.
A method of supplying the surface of a substrate of one material with a surface coating giving the substrate the appearance of another material, in which method there is applied to the substrate surface a composition comprising an aqueous dispersion of solid particles within a resinous carrier and formed by mixing:
- a metal, or metal alloy or inorganic non-metal particulate solid;
- a first product containing particulate organic film-forming vinyl acetate polymer (or copolymer) and having a Tg of between 0° C. and 20° C.;
- and
- a second product containing a particulate organic film-forming acrylate polymer (or copolymer) and having a Tg of between 30° C. and 70° C. and the composition is allowed to set to form the surface coating.
A process for providing a metallic or stone appearance to the surface of an article which processes comprises the steps of:
- (a) applying to the surface a coating of an aqueous coating composition and allowing the coating to dry wherein the coating composition contains:
- i) particles of an organic film-forming vinyl acetate polymer (or copolymer) having a Tg (glass transition temperature) of below 10° C.,
- ii) particles of an organic film-forming acrylate polymer (or copolymer) having a Tg of above 30° C.;
- and
- iii) particles of an opaque, translucent or transparent metal, or metal alloy or inorganic non-metal;
- (b) at least partially drying the coating;
- and
- (c) then removing at least some of the polymer in the coating by rubbing the coating whereby the metal or non-metal particles provide the metallic or stone appearance on the surface of the article.
