Polyamine-functional silane resin

Claim 2

A stable polyamine-functional silane resin which is prepared by reacting: (i) an aminoalkoxysilane and (ii) a hydroxy- and amine-functional compound.

Claim 3

The silane resin of claim 1 wherein the aminoalkoxysilane is of the formula: RNHR.sup.1 Si(R.sup.2).sub.m (OR.sup.3).sub.n wherein R is hydrogen, an alkyl group with no more than four carbon atoms, an aminoalkyl group, alkylaminoalkyl group or alkoxysilano alkyl group with no more than 6 carbon atoms in the alkyl group; R 1 is an alkylene having 1 to 6 carbon atoms, cycloalkylene or aryl group; R 2 is an alkyl having 1 to 10 carbon atoms, cycloalkyl or aryl group; R 3 is an lower alkyl group having 1 to about 4 carbon atoms; m is 0 or 1; n is 3 to 2; and m+n=3.

Claim 4

The silane resin of claim 2 wherein the aminoalkoxysilane is aminoethyltrimethoxysilane, aminopropyltrimethoxysilane, aminopropyltriethoxysilane, aminopropyldimethoxymethylsilane, aminopropyldiethoxymethylsilane, aminoethyl-gamma-aminopropyltrimethoxysilane, or iminobis(propyltrimethoxysilane).

Claim 5

The silane resin of claim 1 wherein the hydroxy and amine functional compound is an amino alcohol, amino polyalcohol, a polyamino alcohol or a polyamino polyalcohol.

Claim 6

The silane resin of claim 4 wherein the hydroxy and amino-functional compound is a polyhydroxy amine.

Claim 7

The silane resin of claim 4 wherein the hydroxy and amine-functional compound is diisopropanolamine, diethanolamine, diisobutanolamine, ethanolamine, isopropanolamine, N-aminoethyl-ethanolamine or N-aminopropyl-diethanolamine.

Claim 8

A curable composition comprising: (i) the reaction product of claim 1 and (ii) a curable material containing a functional group which is an epoxy group, an acrylic group, an isocyanate group or a mixture thereof.
