Abstract
A primer composition is proposed which is capable of greatly improving the adhesive bonding between a substrate surface, in particular, coated with a paint containing a fluorocarbon resin, urethane resin or acrylic resin as the vehicle, and a room temperature-curable silicon rubber composition, in particular, of the type curable by the condensation reaction. The primer composition is a homogeneous solution obtained by dissolving, in an organic solvent, a guanidino group-containing organosilicon compound, such as 3-(tetramethylguanidino)propyl trimethoxy silane, and a so-called silane coupling agent, such as 3-mercaptopropyl trimethoxy silane, in a specified proportion.
