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:
Mixing Nozzle Specifications:
Volume Description Manufacturer 50 mL 0.25 in / 20 element spiral Nordson EFD #7701488 or equivalent
200 mL 0.50 in / 18 element spiral Nordson EFD #7701782, Sulzer-Mixpac #MCH13-18T, or equivalent
200 mL 0.44 in / 20 element Turbo Nordson EFD #7701816 or equivalent
200 mL 0.37 in / 12 element spiral Nordson EFD #7700885 or equivalent
