Incozol grades suitable for Waterproofing

Product Features Benefits
Incozol EH Moisture Triggered Chemistry - atmospheric moisture triggers the curing process Waterproof membranes are capable of curing in a wide range of conditions including extreme temperature ranges and humidity variations. Unlike traditional polyurethane systems they do not release CO2, which often causes gassing and application is not delayed by adverse weather conditions.
Multifunctional (f=4) Faster through-cure leading to increased tensile strength and tougher, more durable films.
Low temperature crystallisation stability (down to -20°C) Ease of handling & storage. Reduced energy costs (no heating required).
Catalyst Free Improved stability with both aliphatic & aromatic PU systems.
Reduced Odour More user friendly for applicator.
