Abstract

Nonaqueous compositions formulated for spray application to a substrate wherein the composition contains a foam-reducing quantity of at least one base-catalyzed reaction product comprising the following reactants: A) at least one compound of formula I R.sup.1(X).sub.3 (I) wherein each X group is a halogen atom or one X group is a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R.sup.1 group to form an epoxy group, and R.sup.1 is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) at least one compound having the formula II R.sup.2X(AO).sub.nY (II) wherein R.sup.2 is a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is --O--, --S--, or --NR.sup.3-- where R.sup.3 is hydrogen or a C.sub.1-C.sub.18 alkyl group; each AO group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group, n is a number of from 0 to 200; and Y is hydrogen, or Y can be a mercapto group or an amino group or a C.sub.1-C.sub.6 alkylamino group in place of a terminal --OH group, provided that when Y is mercapto or an amino group or a C.sub.1-C.sub.6 alkylamino group, n is at least 1; wherein the mole ratio of the linking compound A) to B) is from 0.1:1 to 5:1; and methods for their application.
