Abstract
Disclosed is a method of forming a coating on a substrate. The method comprises applying a silane and, optionally, a titanium catalyst, onto the substrate and allowing the silane to hydrolyze and condense with atmospheric moisture to form an insoluble coating.
Claims23
A method of forming an insoluble coating on a substrate comprising:
- mixing a composition comprising a silane of the formula R.sub.n Si(OR.sup.1).sub.4-n and 50 to 1000 ppm of a titanium catalyst to form a coating mixture, wherein each R is a hydrogen or a hydrocarbon of 1-20 carbon atoms, R.sup.1 is independently an organic group which, when bonded to silicon through the oxygen atom, forms a hydrolyzable substituent and n is 0-2;
- applying the coating mixture on a substrate;
- exposing the coated substrate to atmospheric moisture for a time sufficient to form an insoluble coating, and
- heating the substrate having the insoluble coating at a temperature between 100.degree. and 600.degree. C. for up to 6 hours.
