Low viscosity epoxy resin
PRIME™ 20LV
Gurit
Gurit PRIME™ epoxy infusion systems, now established for over ten years, remain at the forefront of the development of liquid epoxies for 'under the bag' infusion resin processes.
Epoxies are stronger and have higher adhesive properties than other commonly used infusion matrices, such as vinyl esters and polyesters. Epoxy based systems therefore require less resin to achieve greater physical properties, and their use can lead to lighter, stronger and more durable structures.
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.
It has been used successfully for the single-operation moulding of components ranging from narrow shear webs and spars, up to 60 metre blade shells. 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.
