( Polyimide Resin )
ABRON PIR1800 is a reactive resin which can be thermally cured to a cross linked polyimide. This resin has been specifically designed for prepreging application and vacuum assisted resin transfer molding (lower viscosity) for structural composite applications where extended high temperature exposures are required. This resin presents a balance of excellent processability and high thermal stability. Excellent strength retention is maintained upto temperatures of ~ 3500C.

Recommended Storage Conditions :
It is recommended to store the resin at 40C and used with in 3 months of receipt. The resin can be stored for longer durations if stored at sub zero temperatures depending upon the application. Resin should be checked for specifications before usage. The resins have to be brought to room temperature (250C) before application / usage. The resin should be used within 3 days after attaining room temperature. Uncapping of the resin containers should be done only at room temperatures, as the resin is hygroscopic.
Avoid moisture contamination and contact with iron which will react with the resin. Stainless Steel containers are compatible with the resins.
