Abstract: A composition capable of providing, upon hydrolyzing and curing, a protective coating for substrates such as, for example, a plastic substrate having a vacuum metallized or vacuum sputtered surface comprises the reaction product of:(a) an isocyanurate polyisocyanate having the following formula: ##STR1## wherein R.sup.4 is a substituted or unsubstituted aliphatic or cycloaliphatic group having from 1 to 12 carbon atoms or an aryl group and (b) an amino disilane having the formula: ##STR2## wherein R is a lower alkyl having 1 to about 6 carbon atoms; R.sup.1 is a lower alkyl having 1 to about 4 carbon atoms; R.sup.2 and R.sup.3, which may be the same or different, are each substituted or unsubstituted alkylene radicals having 2 to 18 carbon atoms or arylene radicals having 6 to 18 carbon atoms; and a is an integer having values of 0 to 2, the protective coating adhering particularly well to such surfaces and having especially superior resistance to ultraviolet light, humidity, air and heat.

Abstract: A water-activatable adhesive useful for adhering a solar film, polyester (polyethylene terephthalate) film, to glass. The adhesive comprises the reacted product of (A) gamma-isocyanatopropyltriethoxy silane, containing a free isocyanate (NCO) group, and (B) a thermoplastic polyester formed by reacting (i) a dibasic acid selected from the group consisting of terephthalic acid, isophthalic acid and hexahydrophthalic acid, and mixtures thereof, with (ii) a polymethylene glycol of the formula HO(CH.sub.2).sub.x OH where x is an integer from 2 to 10, neopentyl glycol and glycerin, and mixtures thereof, and (iii) an aliphatic dibasic acid selected from the group consisting of those having the formula HOOC(CH.sub.2).sub.n COOH where n is an integer from 1 to 8, and mixtures of such acids, whereby substantially no free NCO remains in the adhesive.Solar film is used for absorbing and/or reflecting solar radiation.
