Trixene SC Bisoxazolidine Additives are latent additives, mainly employed with isocyanate-tipped prepolymers in fully-formulated, 1-K, and 2-K coatings and sealants. There are two distinct types that react with adventitious moisture.

Trixene® SC 7906 is a urethane bisoxazolidine that readily reacts with water and will undergo chain extension and crosslinking with moisture-cure, prepolymer coatings. This product tends to crystallize on storage, but can be melted out before its formulations are used in high-build, void-free coatings.

Trixene SC 7907 is an improved version of Trixene SC 7906 that is non-crystallizing and stable down to -15°C in general use.
