- Features and Benefits
Crestamould® VE 690PA has excellent blister resistance and significantly reduces the occurrence of print through, to produce durable mouldings with an enhanced surface finish.
Applications & Uses
- Applications
- Applications
Crestamould® VE 690PA was developed for use as a skin coat in tooling and marine applications where surface finish is critical.
- Formulation
Crestamould® VE 690PA must be thoroughly stirred and allowed to attain workshop temperature (18°C - 20°C) before use. It needs only the addition of a catalyst to start the curing reaction. Butanox M50, Butanox LA-IN and Trigonox 249VR catalyst can be used, which should be added into the resin.
