PDS-PRIME20LV-7-0411 1 PRIME™ 20LV Epoxy Infusion System n Very low viscosity n Variable infusion times n Very low exotherm even in thick sections n Suitable for infusing very large structures n Germanischer Lloyds approved Introduction PRIME™ 20LV is the next generation of PRIME™ 20 epoxy infusion system, which is specifically designed for use in a variety of resin infusion processes including RTM (resin transfer moulding), SCRIMP™ and RIFT (resin infusion under flexible tooling). PRIME™ 20LV has a much reduced viscosity resin and longer working time, which makes it ideal for infusing very large parts with complex reinforcements in one operation. It maintains the exceptionally low exotherm characteristic, which allows thick sections to be manufactured without risk of premature gelation due to the heat of exothermic reaction. This low exotherm will also help to extend the life of mould tools. PRIME™ 20LV has been used successfully for the single-operation moulding of components ranging from narrow carbon yacht masts, up to 80' yacht hulls and wind turbine blades. It achieves excellent mechanical and physical properties from a moderate (50°C) postcure, offering the finished laminate properties that lie between hand lamination and low-temperature cure prepreg processes. The PRIME™ 20LV system is available with four hardeners, offering a range of working times and cure speeds. This enables the geltime of the resin to be more closely matched to the required infusion time for any particular size of moulded part. The high Tg hardener is ideal for applications requiring 100°C plus thermal capability, whilst maintaining all the other properties of the system. Extensive tests at SP-High Modulus have shown that PRIME™ 20LV with Slow and Extra Slow Hardeners provide an excellent bond to certain types of vinylester resin. This permits production boat builders to use existing polyester gelcoat products with high performance epoxy infusion systems by using a vinylester tie-coat interface. This delivers significant benefits to the production boat builder, in terms of improved durability and performance of hulls/decks whilst retaining the high gloss and ease of gelcoat repairassociated with polyester systems.
