134 Properties of Adhesion Promoters

USE
Manufacturer: Dow Corning
Outstanding properties: versatile adhesion enhancing, clear primer dispersed in low molecular
weight silicone fluid; enhanced bonding/adhesion of RTV and heat cure silicones to many metals,
silicones and some plastics
Recommended applications: used for wide variety of surfaces including FR-4, ceramics, and
metals. Not recommended for plastics
Processing methods: applied in every light, even coat by: wiping, dipping, spraying. Diluting by
factor 2 to 4 with additional solvent may avoid excessive build-up
