Abstract
A combination of a specific first coupling agent, second coupling agent, and carrier solvent is synergistically effective as a primer for improving the adhesion of silicone compositions, especially hydrosilation cured silicone gels, to polymer surfaces. The first coupling agent is a titanium-, boron-, or zirconium-containing coupling agent, or a combination of such. The second coupling agent is a silane coupling agent.
