Processing Guide

Palatal? P65-972 does not contain accelerators. When using the pultrusion process, the curing system should be selected according to the specific equipment, product, process temperature, and pultrusion speed. The recommended amount of curing agent ranges from 0.751 TP3T to 2.01 TP3T of total resin weight.

Maintain shop temperatures between 18°C and 32°C and humidity between 40% and 90%. Maintaining consistent shop conditions helps maintain consistent gel times and helps manufacturers produce a high quality product.
