The PERMACURE AS series is a cold curing system consisting of 3 parts based on proven urethane resin technology. This system can be used for widespread use due to its high cure rate. The benefits include:
- Excellent bench life
- Good humidity resistance
- Low resin wipe
- High tensile and out of box strength
The PERMACURE AS system consists of:
- Part I – phenolic resin in solution
- Part II – modified isocyanine component
- Part III – liquid catalyst
Application: PERMACURE AS is suitable for a wide range of applications. Small or large, moulds or cores, in high or low production runs. Most metals, including steel, iron, bronze and light-alloy castings are can be produced with these products.
Typical addition rates would be 0.5-0.8% of Part I and Part II (BOS) but dependent upon type of sand, equipment in use and core box design.
A wide range of catalysts offers extended bench life properties with some sacrifice of storage stability.
PERMACURE AS Part I – 25, 50 and 200 litre drums, 1000 litre IBC’s
PERMACURE AS Part II – 25, 50 and 200 litre drums, 1000 litre IBC’s
Catalysts Part III – 5, 25, 50 and 200 litre drums
