Epoxy system SR8200 / SD7206 (Fast)

Laminating epoxy system SR8200 / SD7206 with fast hardener

Each kilo includes 0.73 kg resin + 0.27 kg hardener

The SR8200 / SD7206 system exhibits very good mechanical properties, high elongation, fatigue resistance, low odor during application and relatively low cost. The maximum temperature resistance is at least 90 ^oC; however, some post curing is required in order to have service temperature of 60 - 70 ^oC. Typical applications include bows, masts and long service bending products.

Fast hardener SD7206:
Offers fast hardening at low temperature, low surface pollution, demolding of small parts after one night at 20 - 25 ^oC and excellent mechanical properties after post curing at 40 to 60 ^oC.
