- Features and Benefits
Crystic LS 451PA is a DCPD based resin which typically contains 25% to 30% styrene. It therefore has a lower styrene emission than standard LSE resins and during the laminating phase, styrene emissions are typically 20% to 30% lower than conventional LSE resins. The use of Crystic LS 451PA can significantly reduce the occurrence of print through, to produce moldings with an enhanced surface finish.
Applications & Uses
- Markets
- Composites Processing Methods
- Formulation Guidelines
Crystic LS 451PA should be allowed to attain workshop temperature (18°C to 20°C) before use. It requires only the addition of a catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50) which should be added at 2% into the resin and thoroughly dispersed, shortly before use.
- Applications
Crystic LS 451PA is suitable for use in the marine industry and for all general molding requirements.

Technical Details & Test Data
- Additives
The addition of certain pigments, ñllers or extra styrene may adversely affect the properties of Crystic LS 451PA. 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 LS 451PA by curing at workshop temperature (20°C). Some increase in properties may be obtained by post curing. The laminate should be allowed to cure for 24 hours at 20°C, and then be oven cured for 16 hours at 40°C or 3 hours at 80°C.
