CoatOSil™ T-Cure Silane Oligomer may be useful in the development of coating formulations where reactivity with a mercapto silane is desired. This patented oligomer is low in odor compared to standard mercapto silanes and can display a trio of reactive chemistries. In addition to thiol groups, silanol and diols are generated upon the hydrolysis of the silane. It behaves as a reactive diluent within a coating formulation, and is recommended for industrial maintenance applications, automotive, appliance, and coil applications; epoxy primers for metals and flooring, and aurospace and automotive refinishing applications.

- HIGHLIGHTS
Less than 1%wt releasable ethanol; Low odor; Low viscosity; Behaves as reactive diluent within a coating formulation
- Use instructions
Typical dosage levels in coating formulations where mercaptos can react are between 1%wt to 10%wt in existing formulations on a total resin solids basis. Higher levels of CoatOSil T-Cure silane oligomer may also be incorporated into formulations as necessary.
- Potential Application
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.
