Abstract

The present disclosure relates to compositions comprising: an organosilane having the formula: (R1)(3-n) (R2O)nSiR3O(CH2CH2O)a(C3H6O)b R4 wherein: n is 1 or 2; a≥1, b may vary from 0 to 30, with the proviso a≥b; R1 is a hydrocarbon group containing 1 to 12 carbon atoms; R2 is hydrogen or an alkyl group containing 1 to 6 carbon atoms; R3 is a divalent hydrocarbon group containing 2 to 12 carbon atoms; and R4 is hydrogen, R1, or an acetyl group; and at least one of a thermoplastic resin, a thermoset resin, and an elastomer. The present organosilane compositions may be useful for treating various surfaces to render them, among other things, more hydrophilic.
