Abstract
Disclosed is a liquid composition containing a reaction product prepared by reacting a hydrophobic polyol and an organosilicon-containing material. The organosilicon-containing material comprises an organosilicon-containing substance free of functional groups attached to carbon and essentially free of alkali metal ions, having atoms bonded directly to silicon all of which atoms are selected from O, N, and/or Cl. The organosilicon-containing substance additionally has moieties directly bonded to organosilicon which are displaceable by reaction with water and/or alcohol. The reaction product is not capable of being gelled when subjected to a specific three-step gel test, has a ratio of milliequivalents of residual moieties from the organosilicon-containing material which are displaceable by reaction with water and/or alcohol to milliequivalents of hydroxyl moieties from the polyol greater than 1, and is capable of self-curing to a continuous film in the presence of moisture.
