- Processing Parameters
Condition both components to 77°F. Carefully blend T component into R component. Mix for 25-30 seconds with a high speed mixer (3500 rpm). Pour contents into a mold preheated to100-115°F. Post cure for one hour at ambient temperature or 25°F in excess of the maximum anticipated use temperature, not to exceed 200°F. Cool mold below 100°F before demolding part.
