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.
Claims9
A method of forming a film on a substrate;
- the method including a step of:
- (a) applying, by spray coating, a wet, water-borne, film to the substrate;
- the wet film comprising:
- (i) water-borne film forming composition;
- and,
- (ii) desiccant that is at least partially active, in an amount adequate to at least partially take up free water in the wet, water-borne, film;
- (iii) the step of applying comprises mixing, during application, two component streams:
- a first comprising the water-borne film forming composition;
- and, a second comprising the desiccant.
A method at forming a film on a substrate;
- the method comprising:
- (a) applying to the substrate, a coating composition including:
- (i) water;
- (ii) water-borne film former;
- (iii) non-aqueous carrier selected from soluble and water miscible materials;
- and,
- (iv) desiccant that is at least partially active, in an amount effective to at least partially take up free water in the film, once applied to the substrate.
A system for forming a film on a substrate, the system comprising:
- (a) a first component comprising a water-borne film forming composition;
- (b) a second component comprising a desiccant that is at least partially active, in an amount adequate to at least partially take up free water in the wet, water-borne, film;
- and
- (c) apparatus that applies, by spray coating, the wet, waterborne, film by mixing the first and second component streams before application on the substrate.
A system for forming a film on a substrate, the system comprising:
- (a) a first component comprising a water-borne film forming composition;
- (b) a second component comprising a desiccant that is at least partially active, in an amount adequate to at least partially take up free water in the wet, water-borne, film, wherein the desiccant is included in a desiccant composition comprising desiccant dispersed in non-aqueous carrier selected from water miscible and water soluble materials;
- and
- (c) a spray apparatus that applies, by spray coating, a wet, water-borne, film to the substrate by mixing streams of the first and second components near a tip of a spray head, before application on the substrate.
A system for forming a film on a substrate, the system comprising:
- (a) a first component comprising a water-borne film forming composition;
- (b) a second component comprising a desiccant that is at least partially active, in an amount adequate to at least partially take up free water in the wet, water-borne, film;
- and,
- (c) a spray apparatus that applies the first and second components as simultaneous continuous streams that mix as the application occurs.
A method of forming a film on a substrate;
- the method including steps of:
- (a) applying a wet, water-borne, film to the substrate;
- the wet film comprising:
- (i) water-borne film forming composition;
- and,
- (ii) dessicant, that is at least partially active, in an amount adequate to at least partially take up free water in the wet, water-borne, film;
- and,
- (b) allowing the film to set up on the substrate.
A two-part composition set for application of a protective film to a substrate;
- the composition set comprising:
- (a) water-borne film forming composition;
- and,
- (b) separate desiccant composition from the water-borne film forming composition;
- (i) the desiccant composition comprising desiccant suspended in non-aqueous liquid carrier;
- and,
- (ii) the composition set including enough desiccant to absorb at least 50% of free water in the water-borne film forming composition, when the two compositions are mixed together, during application, at a selected volume ratio of at least 1:1 of water-borne film forming composition to desiccant composition.
A desiccant composition suitable for mixing with an water-borne film forming composition during application to a substrate, to facilitate drying of a film on the substrate;
- the desiccant composition comprising:
- (a) desiccant suspended in a non-aqueous carrier in an amount comprising at least 10% and not more than 70%, by weight, of total weight of composition, desiccant.
