SE 84LV LOW TEMPERATURE CURE EPOXY PREPREG ¬ Versatile, high-strength prepreg system Can be processed with vacuum-only processing Excellent tack Low Viscosity – Ideal for use with heavy fibre weights Germanischer Lloyd Certified Lloyd’s Register Certified INTRODUCTION SE 84LV is an exceptionally versatile hot-melt, epoxy prepreg. It can be cured at temperature as low as 80°C (176°F), or can be used for faster moulding of components at 120°C (248°F). This is achieved with an extremely good outlife of up to 8 weeks at 18-22°C (64-72°F). It is a toughened system, and offers excellent mechanical properties on a wide variety of reinforcing fabrics and fibres. SE 84LV is commonly used in vacuum bagging, press-moulding, autoclave and other pressure moulding processes. SE 84LV is a very low viscosity system used with heavy fibre weights where low-flow processing conditions (vacuum bag pressure and minimum cure temperature), are likely to be used. With its high compressive strength it is widely used in large heavily loaded components, such as yacht hulls, and spars. It has been selected for use by various America’s Cup syndicates and boats racing in the Volvo Ocean Race. SE 84LV is widely used in sandwich structures with honeycomb, foam and balsa cores, primarily with the toughened SA 80 Adhesive Film.

PROCESSING NOTES - GENERAL PROCESSING NOTES - CURING CURE CYCLES When preparing the lay-up the prepreg should be removed from the freezer and allowed to thaw in a sealed bag. This may take 6 to 24 hours depending on roll size. This prevents atmospheric moisture from condensing on the prepreg which may cause voiding on cure. The mould surface should be release coated and must have been tested for vacuum integrity prior to lay-up. For a good balance of composite properties, it is recommended that the laminate is cured at 80°C (176°F) for a minimum of 12 hours. A laminate may be cured in two...
