Beschreibung
Zusammenfassung:	A primer composition contains (A) an organic silicon compound having a group of the formula: -CR2R3(CH2)mCOOR1, (B) an organic silane compound of the average compositional formula: R7bR8c(OR9)dSiO(4-b-c-d)/2, (C) an organic silicon compound containing a SiH group, represented by the average compositional formula: R10eHfSiO(4-e-f)/2 and/or an organic silicon compound containing a SiH group and 1-4 divalent or trivalent aromatic rings or a C2-C30 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.
