Following on from the popularity of the Prime 20 Infusion system Gurit have introduced a premium syste for large complex structure and tooling.
The lowest viscosity PRIME™ infusion resin
Suitable for infusing structures that utilise carbon, aramid and glass fibres
Very low exotherm in thick sections
Germanischer Lloyd approved
PRIME™ 27 is suitable for the female moulding of large, complex components incorporating advanced fibres such as carbon and aramid*. Typical projects include spars, hulls and reinforcing structures.
PRIME™ 27 offers outstanding performance in a variety of liquid infusion processes including SCRIMP™, RIFT(resin infusion under flexible tooling), VARTM (vacuum assisted resin transfer moulding) and RTM (resin transfer moulding).
It is Gurit’s premium infusion system, offering high mechanical and thermal properties, lower viscosity, improved wetting out and longer working time than PRIME™ 20LV. It achieves excellent mechanical and physical properties,including a high Tg from a moderate (50°C) postcure.
PRIME™ 27 resin uses PRIME™ 20 hardeners to give a range of working times and cure speeds. This enables the gel time of the resin to be closely matched to the required infusion time for any particular size of moulded part.
The system has an exceptionally low exotherm characteristic, which allows thick sections to be manufactured without risk of premature gelation due to exothermic heat build-up. This low exotherm will also extend the life of mould tools.
All the above properties make PRIME™ 27 a useful product for the infusion of large complex mouldings utilising "higher end" reinforcement fibres such as carbon.
*Unidirectional carbon fibre is acknowledged as difficult to infuse. Please contact a member of our technical team before attempting a carbon infusion with PRIME™ 27
