Product Details
A-306 Silicone Primer (1 oz)
A-306 is a one-component, clear silicone primer specially formulated to enhance adhesion in platinum (addition-cure) silicone systems. It is designed for situations where conventional primers may not provide sufficient bonding performance.
This air-drying primer improves adhesion between silicone elastomers and a wide range of substrates, including metals, glass, ceramics, plastics, and other silicone materials. Compared to A-304, A-306 offers enhanced bonding performance while being more forgiving and easier to work with.
