<p>A primer composition comprising: (A) an organosilicon compound formed by binding an organosilicon compound represented by the general formula (I): <CHEM> wherein R<1> represents a monovalent hydrocarbon group; X represents a hydrogen atom, a lower alkyl group, etc.; and 0 </= a < 0.2, 0 </= b < 0.2 and 1 < C < 4, with an organopolysiloxane represented by the general formula (II): <CHEM> wherein R<2> represents a monovalent hydrocarbon group containing no aliphatic unsaturated group; R<3> represents an alkenyl group; Y represents a hydrogen atom, a lower alkyl group, etc.; and 1.8 < d < 2.2, 0.004 < e < 0.2 and 0 </= f < 0.2, in a particular proportion; (B) an organic titanate; and (C) an organic solvent. This primer composition achieves adhesion with good durability at high temperatures, particularly in high temperature oils.</p> |
