Abstract
Abstract Disclosed is a liquid composition comprising a mixture of (A) a hydrophobic polyol, and (B) an organosilicon-containing material. The organosilicon-containing material is substantially free of unhydrolyzed aminoalkylsilane and comprises an organosilicon-containing substance free of functional groups attached to carbon and essentially free of alkali metal ions. The organosilicon-containing substance has atoms bonded directly to silicon all of which are selected from O, N, and/or Cl. The silicon-containing substance additionally has moieties directly bonded to Si which are displaceable by reaction with water and/or alcohol. At least a part of the silicon-containing substance is hydrolyzed to a compound or a mixture of compounds which contains a residual amount of the moieties directly bonded to Si which are displaceable by reaction with water and/or alcohol. After components (A) and (B) are mixed, the composition is a homogeneous liquid which is capable of self-curing to a continuous film by reaction, with moisture and/or the hydrophobic polyol, of the residual moieties bonded directly to silicon which are displaceable by reaction with water and/or alcohol.
