Epoxy Resin L
Processing time: 90 minutes
Mixing ratio:
100 : 25 parts by weight of resin to hardener
100 : 29 parts by volume of resin to hardener

Laminate structures for vehicle construction in combination with this product and epoxy resin L are approved by the TÜV-Süd. Process instructions/TÜV-Report (unfortunately only in German)
Epoxy Resin L 20
The combination of L 20 and Hardener EPH 161 yields a low-viscosity laminating resin that exhibits superior impregnating and wetting properties to glass, aramid, and carbon fibres. In conjunction with L 20, hardener EPH 161 results in a long service life for the resin compound with very high mechanical and dynamic strengths and perfect curing in both thick (> 2 cm) and thin (1,5 mm) laminates. Before they can obtain the specified mechanical properties, the laminates must be post-cured for about fifteen hours at 60 °C after their initial cold-curing period.
The system L 20 + EPH 161 is approved for the construction of gliders.
