Potential Applications

• Coatings for industrial maintenance applications including storage tanks, bridges and exterior steel structures.
• Coatings requiring curing at elevated temperatures (heat cured formulations), such as coatings for automotive, appliance or coil applications
• Epoxy primers for metals and flooring
• Room temperature cure coatings for applications such as aerospace and automotive re-finishing

CoatOSil T-Cure silane is a mercapto silane oligomer. CoatOSil T-Cure silane exhibits a unique structure, very low odor and an opportunity to make use of the difunctional (diol) leaving group in polyurethane cure chemistry. CoatOSil T-Cure silane offers improved hardness development, corrosion resistance and adhesion.

CoatOSil T-Cure silane, offers excellent adhesion improvement, especially on difficult to stick to soft metals like galvanized steel. While CoatOSil T-Cure silane can slow the cure and extend the potlife of tin catalyzed systems, tertiary amines like triethyl amine (TEA) can be used in lieu of tin, offering formulation options and the ability to tailor cure speed while maintaining good corrosion resistance.

This product has shown improvements in the adhesion of primer to substrate, and topcoat to primer. It can also help speed the hardness development of a 2k polyurethane system over a period of a few days to several weeks.
