Hardener for Epoxy Resin L 385
General information about the System Epoxy Resin L 385 + Hardener 386:
Epoxy Resin L 385 is a new resin system for laminates which is authorised by the Federal Office for Aviation. This resin is suitable for processing glass, carbon and aramid fibres.
- Pot life 120 minutes
- Good mechanical and thermal properties
By exploiting the good mechanical properties, this system is suitable for manufacturing components subject to high static and dynamic loads; in particular in the construction of gliders, power gliders and aeroplanes as well as in the boat and ship building industry, the manufacture of sports equipment and model aircraft.
Following curing at room temperature, the resulting manufactured components can be removed from the mould and processed. Even under unfavourable curing conditions like low temperatures (> 20°C) or high humidity, one obtains tack-free, high-gloss surfaces. The viscosity of the mix is adjusted such that a rapid and optimal wetting of the reinforcing fibres are guaranteed and yet bleeding of the resin from weaves on vertical faces is inhibited.
Mixing ratio:
100 : 35 parts by weight of Epoxy Resin L 385 : Hardener 386
100 : 43 parts by volume of Epoxy Resin L 385 : Hardener 386
Curing time: 24 hours at 20 °C + heat curing 10–15 h at 50–80 °C (at least 40 °C is necessary to get out of the brittle phase)
Hardener 386 should be heat cured in every case.
Advice for storage:
Despite the reduced tendency of our resin systems to crystallise, we recommend storing the containers in a location with low humidity at 15–30 °C. Following removal of materials, the containers have to be carefully sealed in order to avoid the absorption of water, mainly by the hardeners. The aminic hardeners in particular tend to chemically react if exposed to the air, also known as carbamate formation or blushing this can, under certain circumstances, render the material unusable. One recognises this chemical reaction from a white precipitate in the material.
The materials can be kept in their original sealed containers for at least 2 years from the manufacturing date.
The relevant safety instructions for handling epoxy resins and hardening agents as well as our instructions for safe processing have to be followed.
