Laminating epoxy system SR8200 / SD7203 with medium hardener

Each kilo includes 0.73 kg resin + 0.27 kg hardener

The SR8200 / SD7203 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.

Medium hardener SD7203:
Offers fast hardening of laminates at ambient temperature for hand laminating, press or vacuum. Good mechanical properties at ambient temperature, excellent after post cure.
