PRODUCT INFORMATION M103 Chopped Strand Mat PRODUCT DESCRIPTION This product is produced using Advantex® glass fiber. Advantex® glass fiber combines the electrical and mechanical properties of traditional E-glass with the acid corrosion resistance of E-CR glass. The M103 chopped strand mat is made with very low size strands of Advantex® Glass Roving, held together by a powder binder which is extremely soluble in styrene. The basic strand has a sizing system containing a silane coupling agent. This multi-purpose mat is used in numerous applications; M103 chopped strand mat is used in the reinforcement of polyester, vinyl ester and epoxy resins by contact moulding and continuous machine lamination. Its very low strand tex enables higher resin pick up and as a result it is particularly appreciated in manufacture of high quality flat panels where a very good aspect is required, as a surfacing mat and in mould making. Advantex® glass is a patented glass formulation meeting ASTM D578 as a boron-free corrosion resistant E-CR glass fiber and ISO 2078 recommendation for use in acid environments.
