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 Gurit 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 repair associated with polyester systems.
