Laminating & Infusion Systems

PRIME™ 20LV

EPOXY INFUSION SYSTEM
  • Very low viscosity
  • Variable infusion times
  • Very low exotherm even in thick sections
  • Suitable for infusing very large structures
  • Germanischer Lloyds & Lloyds approved

PRIME™ 20LV is the next generation of PRIME™ 20 epoxy infusion resin, specifically designed for use in a variety of resin infusion processes including RTM, SCRIMP™ and RIFT. It has a very low mixed viscosity and long working time, allowing large parts with complex reinforcements to be infused successfully in one operation. It has an exceptionally low exotherm characteristic, which allows thick sections to be manufactured without risk of premature gelation due to exothermic temperature rises. PRIME™ 20LV is both Germanischer Lloyds and Lloyds approved for certified applications.

Typical Applications

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.

Pack Sizes & Availability

PRIME™ 20LV is available in 20/5.2, 220/19 and 1000/180kg resin/hardener quantities for machine mixing/dispense.
