Directions of Use

• 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^oC (149^oF) for one hour, but other temperature and time combinations can work well. Heat curing will improve the physical strength of this coating.
