وصف
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.
