Expanding Foam Sealants
Sika Boom® G-500 S
Sika Boom is a pre-pressurized, portable, one-component, polyurethane foam system applied in a bead form. Sika Boom expands and cures slowly to a semi-rigid, closed cell foam upon reaction with moisture, such as ambient humidity. It is designed for easy dispensing through a straw adapter that is included with each can.
