Abstract: A polyurethane foam sponge that picks up at least 80% of water in a wipe dry performance test is made by variably felting (compressing under heat and pressure) a foam sheet to a compression ratio of about 1.05 to 2.9. The resulting foam sponge has from 5% to 25% of its top and bottom surface portions modified by the variable felting, while its core portion remains substantially unmodified.

Abstract: A polyglycidyl ether compound having a plurality of epoxy groups and a hydroxy group in the molecule is reacted with a silane coupling agent having an isocyanate group, and specifically the hydroxyl group on the polyglycidyl ether compound is reacted with the isocyanate group on the silane coupling agent. Then an organosilicon compound having a plurality of epoxy groups per alkoxysilyl group is synthesized wherein the ratio of epoxy groups to alkoxysilyl groups may be adjusted as desired. The resulting organosilicon compound is useful as a primer and resin modifier.
