Description
Urethane Combi is a hydrophobic chemical grouting compound designed to fill in concrete structural gaps such as a big chasm made by faulty substance, cracks, or joints and to stop high pressure water leaks. When Urethane Combi comes in contact with water, this brown transparent non-flammable liquid expands and quickly seals to a semi-flexible closed-cell polyurethane foam that is resistant to most organic solvents, mild acids, alkali and resistant to micro-organisms. Urethane Combi will seal and cure depending on the amount Urethane CombiAcc used and the temperature conditions (consult reactivity data).
Please read the MSDS literature, prior of usage of the product. Use this product only in well ventilated area. Eye and skin contact should be avoided.
