RESOLTECH 1050 Technical datasheet revision– 16/02/2009 Hardeners 1053 to 1059 Structural Lamination Epoxy System Adjustable pot life from 10 h to 15 min. Room temperature cure & mould release. Final TG above 75°C. The 1050 epoxy laminating system is formulated to manufacture high performance lightweight structures with glass, carbon, aramid and basalt reinforcements with or without post-curing. This new generation system, optimized with a low exothermy, low viscosity and excellent air release properties, is suitable for the manufacture of large structures and composite parts by wet lay-up, infusion, injection moulding or filament winding while guaranteeing low toxicity working conditions to the users. All hardeners mix with a 100:35 ratio and can be pre-blended together to precisely adjust the desired pot life. The 1050 resin + 1053 system is particularly recommended for infusion thanks to it’s low mixed viscosity (205 mPas) and stable viscosity at all working conditions & temperatures. The 1050 resin is available in a thixotropic version (1050T) for wet lay-up application in vertical or overhanging surfaces prone to resin dripping. It is possible to release the parts from the mould without post-curing. 90% of the thermo-mechanical properties of the laminate will be obtained after 7 days at ambient temperature. Laminates produced with the 1050 system will offer very good mechanical properties combined with excellent fatigue resistance. The greatest quality of the RESOLTECH 1050 system is it high inter-laminar properties thanks to its exceptional wetting properties even on aramid reinforcements. Its 5% of elongation to break and 6% of flexion to break mechanical characteristics makes the 1050 system as a prime choice epoxy system for large structural laminates submitted to dynamic working efforts.

Resin 1050 Hardeners 1053, 1054, 1055, 1056, 1058, 1059 MIXING RATIO BY WEIGHT Resin 1050 Hardener 1053~1059 BY VOLUME 100 7 35 WARNING: The mixing ratio must be accurately followed. It is not possible to change the ratio,it would result in lower mechanical properties. The mixture should be thoroughly stirred to ensure full homogeneity. It is important to note that epoxy systems tend to heat up much faster in a pot than as a thin film. It is preferable to only mix the necessary amount usable within the given pot life. Keeping the mixture in flat open containers reduces the risks of...

Resin 1050 Hardeners 1053, 1054, 1055, 1056, 1058, 1059 REACTIVITIES All hardeners can be pre-blended together to obtain an intermediate pot life thanks to their identical mixing ratio of 100:35 and perfect compatibility. For large part infusions, a 50 kg mix of 1050+1053 will grant over 3 hours of pot-life at 20 degrees Gel time measures are realized on Trombotech according to ISO 2535 at 23°C RESIN / HARDENER 70g @ 23 °C 1050 / 1053 10h 1050 / 1054 6h 1050 / 1055 3h30 1050 / 1056 1h30 1050 / 1058 40min 1050 / 1059 15min CURING & POST CURING It is important not to start the curing at...
