Crystic 471PALV should be allowed to attain workshop temperature (18ºC - 20ºC) before use. It requires only the addition of a catalyst to start the curing reaction. The recommended catalysts are Catalyst M (or Butanox M50) or, where ambient temperatures are high, Catalyst O (or Interox LA3). Either catalyst should be added at 1% or 2% into the resin and thoroughly dispersed.

Regulatory & Compliance
- Approvals
Crystic 471PALV is approved by Lloyd’s Register of Shipping for use in the construction of craft under their survey. It also meets the requirements of BS 3532:1990, Type A.
Technical Details & Test Data
- Additives
Crystic 471PALV may be pigmented by the addition of up to 10% of Crystic Pigment Paste. The addition of fillers may change the hardening rate of the resin, and should be evaluated before large scale use.
- Post Curing
Satisfactory laminates for many applications can be made with Crystic 471PALV by curing at workshop temperature (20ºC). For optimum properties and long term performance, however, laminates should be post cured before being put into service. Moldings 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® 471PALV is supplied in 25kg and 200kg containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage
- Crystic® 471PALV should be stored in the dark in suitable closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. 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 wate
