Product Information Unifilo® Continuous Filament Mat for Pultrusion Product Description This is a continuous filament mat designed for pultrusion processes. It has been treated with a suitable bonding resin and coupling agent. The product has good handling properties and good weight uniformity. M-8643 is produced using Advantex® glass fiber. Advantex® glass fiber combines the electrical and mechanical properties of traditional E-glasses with the acid corrosion resistance of E-CR glass. Advantex® glass meets the requirements stated of both E and E-CR glass in both ISO 2078 and ASTM D578. PRODUCT APPLICATION M-8643 mat is designed primarily for the reinforcement of pultruded shapes. The mat has very fast wet-through, good wetout, good conformability and good surface smoothness. Because of its strength, fast pultruding speeds can be used. product availability Weight * (Oz./Sq.
