Abstract
A primer composition contains (A) an organic silicon compound having a group of the formula: --CR.sup.2 R.sup.3 (CH.sub.2).sub.m COOR.sup.1, (B) an organic silane compound of the average compositional formula: R.sup.7.sub.b R.sup.8.sub.c (OR.sup.9).sub.d SiO.sub.(4-b-c-d)/2, (C) an organic silicon compound containing a SiH group, represented by the average compositional formula: R.sup.10.sub.e H.sub.f SiO.sub.(4-e-f)/2 and/or an organic silicon compound containing a SiH group and 1-4 divalent or trivalent aromatic rings or a C.sub.2 -C.sub.30 alkylene group, and (D) an epoxy resin. The primer composition assists in the adhesion of silicone elastomers to metallic and plastic substrates and is useful as adhesive.
