Usage Instructions
Best results will be obtained by applying to thoroughly cleaned and dried parts or materials. It is essential that
surfaces be free of any trace of grease or organic substances.
At room temperature, the product will tack free in approximately 5-7 minutes, and full cure will be achieved in
approximately 48 hours.
Curing may be accelerated by applying moderate heat with either a convection oven or infrared lamps. We
recommend curing in a convection oven at 65°C (149°F) for one hour, but other temperature and time combinations
can work well. Heat curing will improve the physical strength of this coating.
