- Formulation Guidelines
- Crystic 2-8500PA should be allowed to attain workshop temperature (18°C - 20°C) before use. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy.
- Crystic 2 - 8500PA requires only the addition of catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50), which should be added at 1% into the resin.
- The catalyst should be thoroughly incorporated into the resin with a low shear mechanical stirrer where possible.
- Pot Life
Temperature Pot Life Pot life in minutes at 15ºC 42
Pot life in minutes at 20ºC 22 Pot life in minutes at 25ºC 17 The resin, mould and workshop should be at, or above, 15°C before curing is carried out.
- Application
Crystic 2-8500PA is designed for hand laminating and would normally be used with chopped strand mat. Higher specification reinforcements are not recommended.
Additives
- The addition of filler or pigments can adversely affect the hardening of the resin. Users should evaluate the effect of any potential additives before use.
Post curing
- Satisfactory laminates for most non-critical applications can be made with Crystic 2-8500PA by curing at workshop temperature (20°C).
