Rpu 500 Chemical

Product Description

RPU 500 reacts with water forming a Flexible Polyurethane Foam

• Due to its flexibility, the foam absorbs somewhat the movements of the crack.
• Penetrates deep in fine cracks.
• Reacts with water with the formation of carbondioxyde gas. This gas produces a swelling pressure and the resin expands to a foam sealing all water penetration
• Free expansion: 2700 %
• Chemically resistant against water, weak acids and alkali, most organic solvents
• Excellent adhesion to mineral construction materials (such as concrete, cement, brick), metal and certain plastics,
