Best Practices for 3M 08663 Super Silicone Adhesive/Sealants
-
Surface Preparation
Thoroughly clean surfaces to be bonded. Rubber surfaces should be abraded and wiped clean.
-
Application
Apply silicone to area that is to be sealed or bonded. The paste-like consistency makes it easy to tool with a spatula or wooden paddle.
-
Curing
Super Silicones cure from the outside in. At conditions of 75°F and 50% RH, they form a tack free skin within 20 minutes. Tooling is not practical after the skin begins forming. Cure time is affected by humidity, degree of confinement, and thickness of the adhesive/sealant bead. Lower humidity and/or temperature will extend the cure time. Higher humidity and/or temperature will reduce the cure time. In applications where the adhesive/sealant is confined during cure, the time required for proper cure is generally lengthened.
