PRIME™ Infusion Systems

Infusion Systems

PRIME™ infusion systems applications range from single-operation moulding of carbon yacht masts, up to 80' yacht hulls and wind turbine blades.  PRIME™ epoxy infusion systems have been used successfully for over 20 years and today are at the forefront of the development of liquid epoxies for "under the bag" infusion processes, including:

  • SCRIMP™
  • RIFT (resin infusion under flexible tooling)
  • VARTM (vacuum assisted resin transfer moulding)

PRIME™ 37 Low Toxicity Epoxy Infusion System

PRIME™ 37 has been developed to deliver exceptional laminate quality for a range of liquid infusion composite processes.  Gurit’s unique fibre wetting technology reduces infusion time and improves laminate quality

Gurit fibre wetting technology

The cure characteristics of PRIME™ 37 have also been optimised:

  • Mixed viscosity remains lower for longer
  • Faster through-cure, avoiding a low-strength “sugary” phase
  • Improved exotherm control

PRIME™ 37 is Lloyd's certified and is produced with bio-based content as standard.  By using the award winning Ampreg™ 3X low toxicity hardeners, PRIME™ 37 has market leading health and safety, and also allows customers to take advantage of the blend-able hardener speeds which can be tailored to suit each application.

    For large infusions involving relatively thick sections, being able to control the reactivity is key. When using Gurit’s new PRIME™ 37 system, Airborne were pleased to note that this system combined familiarity with improved performance and the ability to control their process to an exceptional degree. This greatly benefits them whether it be manufacturing a large composite gangway, or during RTM processes involving very thick laminates.
