Crestapol Resin Systems for Pultrusion ®

CRESTAPOL® is a very low viscosity, methacrylate-based thermosetting resin, developed for use in pultrusion in conjunction with high levels (up to 200phr) of alumina trihydrate (ATH) fire retardant filler to produce profiles with excellent low smoke, low toxicity fire performance. CRESTAPOL 1212 and 1214 use standard initiators and additives associated with pultrusion, and can be processed on standard pultrusion equipment without modification. CRESTAPOL 1214 is a modified urethane acrylate resin which gives a high quality surface finish and very low shrink. Crestapol 1214 has undergone repated...

Pultrusion Guidelines Typical Formulation (dispersed in mma or styrene solvent) (internal release agent added @ 1 pbw on total resin + filler) (First section unheated to prevent It is recommended starting up with dry rovings in the die, then gradually increasing the wet-out of the rovings thus allowing simultaneous build-up of cured resin in the area of the pullers, thus ensuring grip is always adequate. (It is essential to ensure that there is never a situation of fully cured profile in the die and dry rovings * A suitable grade of ATH used for pultrusion, or equivalent product with a median...
