Abstract
The present invention relates to a method of producing an elastic coating which is suitable for waterproofing, by using film forming onto a solid surface, textile or mesh. In this method, a dispersion which comprises i) one or more adhesives and/or coagulating aggregates, mainly in solid form, ii) one or more polymers, and iii) one or more surface-active agents, is brought into contact with a coagulator of the surface-active agent of the dispersion. The present invention also relates to a coating which is prepared by using the present method.

A method of producing, from a polymer dispersion, an elastic coating which is suitable for waterproofing, by using film-forming, onto a solid, mesh-like or porous substrate, wherein in order to coat the substrate, a dispersion that comprises, dispersed in a liquid phase,
- i) one or more aggregates, which are at least mainly in solid form,
- ii) one or more polymers,
- iii) one or more surface-active agents, and
- iv) one or more coagulators,
- is applied onto a substrate, and the elastic coating is formed from the dispersion, no earlier than during the application, by removing at least a portion of the liquid phase from the dispersion.
A method of forming a waterproof elastic coating on a substrate, the method comprising:
- providing a film-forming polymer dispersion comprising, dispersed within an aqueous phase, at least:
- an acrylate polymer comprising first acrylate polymer particles having a first average size and second acrylate polymer particles having a second average size smaller than the first average size;
- a plurality of inorganic particles for filling a volume between the first and second acrylate polymer particles;
- and
- at least one coagulator for promoting film formation of the dispersion;
- applying the dispersion to the substrate:
- and
- removing at least a portion of a liquid phase from the dispersion to form the waterproof elastic coating on the substrate.
