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.

INCOZOL® LVis a reactive diluent designed to help producers of polyurethane coatings and sealants attain low VOC systems. It is used in the formulation of two component coatings where INCOZOL® LV replaces a portion of the polyol component, for example, automotive refinish and OEM coatings. Other uses include high solids PU coatings for boats, industrial maintenance, aircraft, automotive sealants, anti-graffiti lacquers and waterproof coatings.

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® 2 acts as an effective moisture scavenger in polyurethane coatings and sealants. It is used to eliminate moisture from solvents, polyols and prepolymers and also from plasticisers and pigments. It removes residual moisture from the formulation and prevents bubbling and downglossing caused by high moisture levels either on the substrate or from the atmosphere. INCOZOL® 2 is used in one or two component systems but is not generally recommended in one component systems with a low NCO content.
