Abstract
Techniques and compositions for applying films to a variety of substrates, from water-borne coating compositions, are provided. The techniques involve providing desiccant and applying the desiccant with water-borne film-forming composition, in application to a substrate. The desiccant composition provides for take up of free water in of the film-forming composition, without total reliance on ambient conditions, to advantage. Compositions, methods, techniques and resulting constructions are described. The techniques can be applied in wet thick film applications, but are not limited to such applications.
Claims22
A method of forming a film on a substrate;
- the method including a step of:
- (a) applying, by spray coating, a coating to the substrate;
- the coating comprising:
- (i) water-borne film forming composition comprising a latex provided as a dispersion of polymer particles in an aqueous medium;
- and,
- (ii) desiccant composition that is at least partially active, in an amount adequate to at least partially take up free water in the water-borne film;
- (iii) the step of applying comprises:
- (A) mixing two component streams comprising:
- a first comprising the water-borne film forming composition;
- and, a second comprising the desiccant composition to form the coating in a volume ratio of the water-borne film forming composition and the desiccant composition of 2:1 to 8:1, inclusive;
- and,
- (B) applying the coating to the substrate and forming the film on the substrate.
