Description
This is a solvent-borne silicone primer, ordered under part number 28159, applied as a thin air-drying film ahead of a silicone adhesive or sealant. It conditions clean metal, glass and other rigid substrates so the cured silicone anchors to the surface rather than peeling from it. Specify it where the joint carries load or faces service conditions that would test an unprimed bond.

Frequently asked
What does a silicone primer actually do?
It leaves a reactive film that links the substrate to the curing silicone, producing a stronger and more durable bond than the silicone would achieve on its own. The manufacturer datasheet lists the substrates the primer has been evaluated against.
Does every silicone joint need priming?
No. Many silicone sealants self-adhere to clean surfaces. Prime when the substrate is difficult, the bond carries load, or long-term environmental exposure is expected — and always confirm the decision with an adhesion trial on your own parts.
