INCOZOL® EH is a urethane bis-oxazolidine latent hardener for use in 1K polyurethane coatings, adhesives and sealants. Used in conjunction with low NCO polyurethane prepolymers, this hardener accelerates the cure of the prepolymer through a moisture triggered mechanism to afford crosslinking benefits to the 1K urethane. In addition, it enhances properties such as through cure development and mechanical strength through the elimination of CO2 gassing in high build, high solids PU systems. INCOZOL® EH confers tolerance to the repeated opening of containers and can be used as a versatile curing agent with 2 or 4 functional mix ratios.

INCOZOL® 4 is a bis-oxazolidine curing agent, which hydrolyses on exposure to moisture, yielding a reactive amine and hydroxyl functional cross-linking agent. INCOZOL® 4 can be used in both one and two component PU systems. In one component systems it is normally used with aliphatic prepolymers. In two component systems it can also be used with aromatic prepolymers or isocyanates.
