Epoxy Resin L + Hardener GL 1 (30 min)

Epoxy Resin L + Hardener GL 1 (30 minutes), set of two componets

• Low viscosity (820 mPas at 25 °C)
• Fully cures at 10 °C
• Glass transition temperature (Tg) > 80 °C (post-curing at 70 °C / 15 h)
• Ambient curing does not result in brittleness (at 20 °C)
• High static and dynamic strength

Epoxy Resin L with Hardener GL 1 is a frequently used laminating resin system from the R&G delivery program. Due to its low surface tension, good adhesion and low curing shrinkage, it is also very suitable for bonding wood, metal and PS rigid foams such as Styropor®. It is ideal for impregnating glass, aramid and carbon fibers and offers a very good price/performance ratio.

Approval by the Germanische Lloyd for the construction of boats and rotor blades for wind turbines.

Processing time: approx. 30 minutes

Mixing ratio:
100 : 30 parts by weight Epoxy Resin L : Hardener GL 1
100 : 35 parts by volume Epoxy Resin L : Hardener GL 1

Suitable for the following processing methods:

• Resin infusion (RI)
• RTM (resin transfer moulding)
• Press moulding
• Vacuum moulding
• Filament winding
• Hand laminating

The resin component itself is absolutely free of crystallization due to its Bisphenol A/F base! The resin system is ambient curing and develops no distinctive brittleness even at curing temperatures below 20 °C. We however recommend, to improve the mechanical and physical properties, to perform a post-curing at least at 40 °C over 15 h.

Processing times with Epoxy Resin L depending on the proportion of hardener GL 1 / GL 2*:

Approx. potlife in minutes (100 g at 23 °C with Epoxy Resin L)	Quantity of Hardener GL 1 in %	Quantity of Hardener GL 2 in %
210	0	100
150	10	90
125	20	80
100	30	70
85	40	60
60	50	50
50	60	40
43	70	30
38	80	20
34	90	10
30	100	0

*Both hardeners can be mixed as required. The mixing ratio of 100: 30 resin to hardener remains unchanged.
