Product Details
Description
Epoxy Resin L + Hardener GL 1 (30 minutes), set of two components
- 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.

Overview of charactericstics of Epoxy Resin L + Hardener GL 1:
| Norm | Unit | Result | Requirement GL | |
| Density | DIN EN ISO 1183-1 | g/cm³ | 1.171 | - |
| Flexural strength | DIN EN ISO 178 | MPa | 135 | ≥ 100 |
| Tensile modulus | DIN EN ISO 527-2 | MPa | 3490 | ≥ 2700 |
| Tensile strength | DIN EN ISO 527-2 | MPa | 74 | ≥ 55 |
| Elongation at break | DIN EN ISO 527-2 | % | 3.5 | ≥ 2.5 |
| Heat deflection temperature (HDT)* | DIN EN ISO 75-2 | °C | 74 | ≥ 70 |
| Water resumption (after 168 h) | according to DIN EN ISO 175 |
mg | 31 | ≤ 50 |
*24 h at 23 °C + 16 h at 80 °C
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.
