General purpose structural fiberglass tape ideal for tabbing. WEST SYSTEM Episize Biaxial tape is ideal for most structural fiberglass applications where strength is more important that weight. Two layers of non-woven E-glass are set at a ±45 orientation and lightly stitched to produce a 17oz material that can be easily wetted out by hand to achieve a high resin to fiber ratio. The strand orientation makes this tape ideal for tabbing with its ability to lay down nicely on moderate compound curves without bunching or creating air pockets. West System Episize Biaxial tapes are the right choice for structural reinforcement and tabbing applications.
