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 odour 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.

The potential applications for CoatOSil T-Cure include:

• 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

Features & Benefits

• Less than 1%wt releasable ethanol
• Low odour
• Low viscosity
• Behaves as reactive diluent within a coating formulation
• Can be used in virtually all coatings chemistries where mercapto groups can react: Isocyanates, Epoxies, Acrylates

Benefits of CoatOSil T-Sure silane oligomer in NCO coating formulations:

• Higher initial surface hardness of coatings
• QUV-B gloss and color change was equal to the control. QUV-A results were similar when tested.
• NSST corrosion resistance appears to have been better than the control
• Greater open time during cure, which may potentially lead to a longer pot-life after mixing
• An excellent candidate to consider for both castable and RIM urethane and urea applications
