Instructions For Use – Surface Preparation
IS 5628E will bond to clean surfaces without the aid of primers. These surfaces typically include many metals, glass, ceramic, and silicone rubber. A preliminary
check should be made to determine bonding effects for each specific application. For difficult-to-bond substrates, use of a primer will usually improve adhesion.
Momentive performance materials silicone primers SS4004P, SS4044P and SS4179 are recommended for use with this adhesive/sealant. Where adhesion is required, surfaces should be thoroughly cleaned with a suitable solvent such as iso propylalcohol (IPA) or methyl ethyl ketone (MEK) to remove dirt,
oil and grease. The surface should be wiped dry before applying the adhesive/sealant.
Momentive performance materials Silicone IS 5628E adhesive/sealant may be applied directly to clean substrate. Where broad surfaces are to be mated, sealant should be applied in a thin, less than 6 mm diameter, bead or ribbon around the edge of the surface to be bonded.
