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.

PRODUCT INFORMATION WE91-2 prepreg can be used with both SPRINT® and SparPreg™ products. It is supplied with a poly backer and can be applied to the substrate with either side against the tool. In order to maximise the potential of the prepreg product range please contact the Gurit Composite Processing Department. Contact details are on the back of this Product Data Sheet. General prepreg / SPRINT® working practices apply to these products, details of which can be obtained from the Gurit Guide to Composites or by contacting the above department.
