Crystic 2-406PA should be allowed to attain workshop temperature (18ºC - 20ºC) before use. It needs only the addition of a catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50). The catalyst should be added at 1% or 2% into the resin and thoroughly dispersed, shortly before use.
The geltime of the resin can be approximately determined from the table below.

Regulatory & Compliance
- Quality Standards
- Approvals
Crystic 2-406PA is approved by Lloyd’s Register of Shipping for the construction of craft under their survey.
It also meets the requirements of BS 3532 : 1990 : Type A
Technical Details & Test Data
- Additives
The addition of certain pigments, fillers or extra styrene may adversely affect the properties of Crystic 2-406PA. Users should seek advice from our Technical Service Department before making any additions.
- Post Curing
Satisfactory laminates for many applications can be made from Crystic 2-406PA by curing at workshop temperature (20ºC). For optimum properties and long term performance, however, laminates should be post cured before being put into service. The laminate should be allowed to cure for 24 hours at 20ºC, and then be oven cured for 3 hours at 80ºC or 16 hours at 40ºC.
Packaging & Availability
- Packaging Type
- Packaging
Crystic 2-406PA is supplied in 25kg and 200 kg containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage
Crystic 2-406PA should be stored in the dark in suitable closed containers. It is recommended that the storage temperature should be less than 20ºC where practical, but should not exceed 30ºC. Ideally, containers should be opened only immediately prior to use. Where they have to be stored outside, it is recommended that they are kept in a horizontal position to avoid the possible ingress of water.
