Selsil Premium Flex Pu Foam
Selsil Premium Flex Pu Foam is a single-component, polyurethane-based, elastic foam applied with a gun. It cures with moisture in the air. It is specially designed to provide high flexibility. Filling vibratory structural voids; it is used to seal joints, connections and cracks.
- It is suitable for use at low temperatures.
- It allows physical movement without structural deformation.
- It provides excellent resistance to shock and impact.
- It provides heat and sound insulation.
- Once cured, it can be cut and painted.
- Excellent adhesion to wood, concrete, brick, stone, metal, plastics such as EPS and XPS, PU foam and uPVC.
