Kemko® 181, Polyurea Membrane is a two- component, short work life/fast curing, elastomeric, polyurea membrane designed for interior and exterior use. It cures to a tough, chemical and abrasion resistant material suitable for waterproofing, corrosion protection and containment of many aqueous chemical solutions. Kemko® 181 may be applied on most construction substrates including concrete, asphalt, steel, and wood. Neat binder may be used for filling non-structural cracks, saw cuts and control joints in concrete. Cured Kemko® 181 has excellent resistance to vehicular impact and abrasion, most automotive and aircraft fluids and pavement deicing chemicals. Its short cure cycle, tolerance of surface dampness and elastomeric mechanical properties make it ideally suited for a wide variety of membrane, coating and lining applications. Each type of repair may have specific application and performance requirements. Evaluation of trial mixes particularly under low temperature, damp conditions prior to installation is recommended.
Unlike other elastomeric polyurea binders, Kemko® 181 does net contain volatile solvents or plasticizers and therefore does not embrittle nor degrade when exposed to sunlight for long periods of time and is environmentally safe. Kemko® 181 is self-priming on most dry and damp substrates and is suitable for either manual or spray application. The product has a convenient 1:1 (by vol.) mixing ratio and a fast cure cycle for short downtimes.Technical Data Sheet
