Epoxy Resin L + Hardener EPH 161 (90 minutes), set of two components
New hardener formulation with improved properties (see below under Additional Information "Comparative Data "*)
- Free from DETA
- Low viscosity, free of solvents and fillers
- Fast impregnation of glass, aramid and carbon fibres
- Tack-free curing of even the thinnest layers
- High static and dynamic strength*
- Better milling edge quality
- Increased heat distortion temperature after heat curing
*Higher stiffness (+ approx. 17 %), tendency higher strength
Processing at room temperature. An optional heat hardening of 15 h at 100° C further improves the strength values and heat distortion temperature considerably.
Epoxy resin L, together with Hardener EPH 161, exhibits excellent mechanical properties as required, for example, in aircraft construction. However, aviation approval is not given.
TÜV-Süd has tested the system in various laminate structures and determined its suitability for vehicle construction (see below under Additional Information "TÜV Report").
