Технические характеристики
Epoxy resin L 385 is a resin system for laminates which is authorised by the Federal Office for Aviation. This resin has variable pot lives and is suitable for processing glass, carbon and aramid fibres.- Extraordinary good physiological compatibility
- Pot life 20 minutes (hardener 385)
- 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 resin L 385 : Hardener 385
100 : 43 parts by volume of resin L 385 : Hardener 385
Curing time (20°C): 24 hours + heat curing 10–15 h at 50–80 °C
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.
