Infusion Resin (PRIME™ 20LV)

> Very low viscosity - minimising infusion time and blade production time > Variable infusion times - a range of different speeds of hardener to fit any process > Very low exotherm even in thick sections - extending mould life > Suitable for infusing very large structures - even in hot climates > Certified - Germanischer Lloyd approved

Infusion Resin for Wind Turbine Blades

Deciding whether a resin system is suitable for an infusion process requires careful thought to be given to many different aspects of the production process including the component size, ambient conditions, reinforcement, thermal and mechanical properties and blade certification.

The future optimisation of the production process must also be considered; mould utilisation and cycle time is paramount to reducing cost.  In order to achieve this, a robust infusion resin that offers a range of speeds that can be tailored to continually improved processes is essential.

By recognising this need to reduce cost through process optimisation, Gurit is able to offer such a versatile system through the PRIME™ infusion system, which has excellent properties with a range of hardeners that can tailored to fit virtually all production processes.

Infusing with PRIME™ Infusion Resin

• PRIME™ 20LV - Epoxy Infusion System (v7)
  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.

PRIME™ infusion resin 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 an 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.

The PRIME™ infusion system 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 process.

The PRIME™ infusion system is available with a range of hardeners, offering a range of working times and cure speeds providing versatility to manufacture a wide range of components from UD spar-cap laminates to single-shot full blade infusion processes.
