Incozol® 4

Incozol® 4 by Incorez is bis-oxazolidine latent hardener for high-build coatings without carbon dioxide gassing. It hydrolyzes on exposure to moisture, yielding a reactive amine and hydroxyl functional crosslinking agent. Offers stability to repeated opening of containers and accelerates the curing of low NCO PU pre-polymers. It has an excellent shelf life, low equivalent weight and can be used as bi- or tetra-functional latent hardener. It is recommended for high-solids (low-VOC) moisture cure varnishes and coatings systems for roofing, balcony and floor. In one-component systems, it is normally used with aliphatic pre-polymers. In two-component systems, it can also be used with aromatic pre-polymers or isocyanates. Incozol® 4 offers faster through cure which leads to increased tensile strength, tougher and more durable coatings.
