Crystic® Polyester Resin 397PA
Crystic® Polyester Resin 397PA is a pre-accelerated isophthalic/neopentyl glycol polyester resin with a high heat deflection temperature and good water and chemical resistance. It is recommended for the fabrication of high-performance laminates for critical applications in aggressive environments. This product is suitable for contact molding and filament winding processes.

- Additives
Crystic 397PA may be pigmented by the addition of up to 5% Crystic Pigment Paste. Certain pigments, fillers or extra styrene can adversely affect the food taint, toxicity and chemical resistant properties of Crystic 397PA. Customers should therefore satisfy themselves that any additions made willl give the performance required.
- Approvals
Crystic 397PA is approved by Wine Laboratories Ltd for vessels to contain Wines and sherries up to 25% alcohol content.

- Post Curing
Satisfactory laminates for many applications can be made with Crystic 397PA by curing at workshop temperature (20°C). However, for optimum chemical, water and heat resistant properties, laminates must be post cured before being put into service. Moldings should be allowed to cure for 24 hours at 20°C and then be oven cured for 3 hours at 80°C. Moldings which are to be used with foodstuffs should be allowed to cure for 24 hours at 20°C and then be oven cured for a minimum of 3 hours at 85°C. They should be thoroughly wet-steam cleaned for at least one hour prior to use. If wetsteam cleaning is not practical, suitably shaped moldings can be filled with hot water (60°C- 80°C) containing nonperfumed detergent. After 2 hours, they should be emptied and thoroughly rinsed with several batches of clean hot water. These precautions are essential to avoid the tainting of foodstuffs.
