Abstract
A primer composition comprises (A) an organosilicon compound having different alkoxy groups in its molecule, (B) a tetraalkoxytitanium, (C) an acid and water, and (D) an organic solvent. The composition shows excellent adhesion properties to fluororesin coating materials, acrylic resin coating materials, etc. When applied to the surface of a metal coated with such a coating material, the primer composition is capable of providing a remarkably enhanced adhesion, for example, between a silicone elastomer and the coated metal.
