Q & A

What is the HDT (heat deflection temperature) of Crystic 397 PA, and to obtain its maximum what is the post curing schedule?

Crystic 397 PA has a HDT of 117 Deg C on a fully cured laminate. The post curing schedule requires the laminate to be at 24 hours @ 20 Deg C followed by 5 hours @ 80 Deg C then 3 hours @ 120 Deg C . please read tech data sheet attached.

I have been using Crystic 474 pa Polyester resin for moulding camper van roofs, can you advise the difference between this resin and Crystic 397pa.

They are only similar in the respect that they both have heat distortion points higher than typical resins - chemically they are quite different. C.474PA is an orthophthalic  resin with a high maleic content to push up the heat distortion point. C.379PA is an isophthalic / Npg resin so will have better overall properties and higher chemical resistance , particularly towards alkaline chemicals like caustic soda .
