WE91-2 MEDIUM TACK GLASS PREPREG ¬ WE91-2 medium tack resin matrix High flow matrix INTRODUCTION WE 91 is part of Gurit’s comprehensive offering of structural composite product solutions comprising of 3 main product groups; Prepreg, SPRINT® and SparPreg®. This unique product range provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other Gurit products from within the range. Gurit’s WE91 prepreg product range comprises of two tack variants; WE911 high tack and WE91-2 medium tack prepregs. WE91 is a high flow epoxy prepreg ideally suited to structural composite component manufacture. It can be cured at temperatures as low as 85⁰C / 185⁰F, but can also be used for the rapid manufacture of components through its 45-minute cure at 120°C / 250°F. All of this can be achieved together with an out-life of 60 days at 21°C / 70°F. WE91-2 is designed for vacuum bag processing and offers excellent mechanical performance on glass and carbon fibre reinforcements.
