Biresin CR122/CH122-3 Epoxy Laminating System – 1.3kg

Features & Advantages of Biresin CR122/CH122-3 Epoxy Laminating System Excellent impregnation and good non draining properties due to optimized mixed viscosity. Biresin® CR122 (A) with hardeners (B) Biresin® CH122-3 and CH122-5 are DNV GL approved, certificate no. TAK00001YB. Glass transition temperatures of up to 120°C are achievable depending on curing conditions. Biresin® CR122 (A) with hardeners (B) Biresin® CH122-3 and CH122-5 are approved by Luftfahrt-Bundesamt (German Aeronautics Federal Office) as resin system for GRP, CRP and ARP parts for gliders and power gliders (see Datasheet). Demoulding is possible after RT curing when using the fastest curing agents (B) Biresin® CH122- 1, CH122-3 and CH122-5. Physical Data Resin (A) Hardener (B) Mixing Ratio, parts by – Weight 100 30 Mixing Ration, parts by – Volume 100 37 Colour Translucent colourless to brownish Viscosity, 25°C – mPa.s ~850 ~15 Density – g/ml 1.17 0.94 Processing The material and processing temperatures should be from 18 to 35°C. The mixing ratio must be followed accurately to obtain best results. Deviating from the correct mix ratio will lead to lower performance. The final mechanical and thermal values are dependent on the applied postcuring cycles. Parts produced with Biresin® CH122-1 CH122-3 and CH122-5 hardeners (B) can be demoulded after cure at room temperature. Postcuring is recommended (See Datasheet). Storage Minimum shelf life of Biresin® CR122 resin (A) is 24 month and of Biresin® CH122-3 hardener (B) is 12 month under room conditions (18 – 25°C), when stored in original unopened containers. After prolonged storage at low temperature, crystallisation of resin (A) may occur. This is easily removed by warming up for a sufficient time to a minimum of 60°C. Containers must be closed tightly immediately after use. The residual material needs to be used up as soon as possible.
