General information about the System L 1100 + Hardener 294/295
- Low viscosity, free of solvents and fillers
- Pot life can be varied from ca 15 minutes to 400 minutes
- Fast impregnation of glass, aramid, and carbon fibres
- High static and dynamic strength
- Approved by Germanischer Lloyd (wind turbine blades and boat building)
The laminating resin L 1100 not only presents an innovative epoxy resin system, but is also characterised by a particularly impressive price-performance ratio. The hardeners EPH 294, 295 can be mixed in any combination serving to adapt the resin system's reactivity to the most diverse demands placed on the processing time.
The mixing ratio of resin to hardener nevertheless remains constant at 100 : 30 parts by weight.
The systems are preliminarycold curers, so they should be subjected to a subsequent approx. ten-hour period of hot curing (50–80 °C) before they can develop their optimal properties.
Epoxy resin L 1100 is ideal for impregnating glass, aramid, and carbon fibres. It can be processed in all of the customary methods, e.g. hand lay-up operations, pressure and vacuum impregnation, press moulding, winding, etc.
The resin component inclines to crystallization if stored below 18 °C, heating in a warm water bath or curing oven will liquefy the solid bulk. R&G epoxy resin L is particularly suitable as a non-crystallising alternative to epoxy resin L1100. Excellent mechanical properties are obtained with the hardeners EPH 294 and EPH 295.
The mix viscosity is once again significantly reduced compared to L 1100. This viscosity is calculated to be in the range from 200 to 250 mPa.s thereby making the system tailor made for employing in the RTM process as well as in vacuum infusion.

When using epoxy resin L / hardener 294 and 295, we recommend warm curing at a minimum of 40 °C for 6-8 h to eliminate the brittleness caused by curing the system at room temperature. A Tg of max. 88 °C is also obtained with this combination. The given pot lives also remain the same while the mixing ratios vary:
Epoxy resin L + hardener EPH 294: 100 : 31 parts by weight or 100 : 39 parts by volume
Epoxy resin L + hardener EPH 295: 100 : 31 parts by weight or 100 : 39 parts by volume
Please compose your own work packages by ordering resin and hardener individually, also for small quantities.
Extended storage time: 36 months
