ABSTRACT:
Primer composition comprising a silane coupling agent, an alkoxysilylated NCO-containing urethane prepolymer which is prepared by reacting a polyisocyanate with a diol to give an NCO-containing urethane prepolymer, and reacting the resulting NCO-containing urethane prepolymer with a trialkoxysilane having a functional group active to NCO group wherein a part of whole of the remaining NCO groups of the high molecular weight polyisocyanate are reacted with the silane. Said primer composition has excellent plasticizer resistance, solvent resistance and film-forming properties and further improved adhesin properties to glass, metals, ceramics, and is useful as a primer for various adhesives, particularly for applying to glass, metals, and ceramics.
