Abstract
Disclosed is a resin comprising a reaction product prepared by partially reacting to homogeneity a hydrophobic polyol and an organosilicon-containing material comprising an organosilicon-containing substance. The organosilicon-containing substance has atoms bonded directly to silicon, all of which atoms are selected from oxygen, nitrogen, and/or chlorine, and additionally has moieties directly bonded to silicon which are easily displaceable by reaction with water and/or alcohol. At least a part of the organosilicon-containing substance is hydrolyzed. The reaction product is homogeneous and contains residual hydroxyl moieties from the hydrophobic polyol and residual moieties bonded directly to silicon which are easily displaceable. the reaction product is capable of self-curing, optionally with a catalyst, by reaction with moisture and/or with the residual hydroxyl moieties, of the residual moieties directly bonded to silicon which are easily displaceable.
