MIXING INSTRUCTIONS
1. Weigh out required amount of P.C.601, and weigh into it 13 parts P.C.90 per 100 parts P.C.601; or 45 parts P.C.150 per 100 parts P.C.601.
2. Mix curing agent in thoroughly.
3. Evacuate for 2 - 5 minutes if void-free castings are required.
4. Pour into cavity or mold.
CURE SCHEDULE
P.C.90 & P.C.150 - Cure at room temperature for 4- 8 hours with full properties after 24 hours.
