Cry-A-Cure (BPO) is the initiator used for the polymerization of all Cryl-A-Flex MMA based resins and Cryl-A-Tex polymer concrete.
Cryl-A-Cure (BPO) is sold in two different package sizes. It is important to know the volume in ounces of each:
- 1 Gallon Plastic Pail = ~100 ounces
- 55 lb. box = ~1100 ounces
The number of ounces (volume) of BPO to be mixed with the MMA resins is dependent on the substrate / material temperature. See the Cryl-A-Flex Mixing Chart for mixing volumes.
When determining how much BPO to purchase for a jobsite, it is good to assume the substrate / material temperature will be 40°F or 10 degrees lower than the anticipated substrate temperature, which would require the most ounces of BPO per 1 gallon of resin or 1 quart of Cryl-A-Cove.
This will ensure that you always have enough BPO for your job.
