Technical Details & Test Data

Mix Ratio Data

To 100 parts by weight of Epocast® 1633 A resin, add 50 parts by weight of Epocast® 1633 B hardener. Due to the very fast setting properties of Epocast® 1633 A/B, hand mixing of the components should be avoided.

Processing Information

To 100 parts by weight of Epocast® 1633 A resin, add 50 parts by weight of Epocast® 1633 B hardener. Due to the very fast setting properties of Epocast® 1633 A/B, hand mixing of the components should be avoided. Epocast® 1633 A/B is available in 50 mL and 200 mL twin cartridges. For best results, Epocast® 1633 A/B should be dispensed using manual or pneumatic dispensing equipment through a suitable mixing nozzle as shown below:
