Epoxy resins

SR 8500 A multi purpose epoxy system which will suit many composite applications.

Recommended for large size parts.

Good mechanical properties. Good performance/price ratio.

The SR 8500 / SD 860x system is well suited for the production of composite parts working at temperatures of up to 70°C. A post cure treatment is strongly suggested.
Solvent and reactive Diluent free
Without classified Toxic products (T)
A resin to be combined with two hardeners, used pure or mixable in any proportions
Cure at ambient temperature and post cure at 40 to 60 °C

The two hardeners available have extreme reactivities:

SD 8605, fast hardener, accelerator.
SD 8601, ultra slow hardener, low viscosity with high wetting characteristics.

The hardeners can be blended to different ratios in order to adjust for the working time required.

Also exists in a thixotropic formulation, SR 8500 Black Gel.

SR 8150 / SD 815 Bx Flexible epoxy systems

Flexible: 80 to 110 % of elongation at break in tension; shock resistance over 150 KJ /m2

Low viscosity of the mixes
Unfilled and translucent
Advantages compare to polyurethane: does not foam when in contact with humidity; memory of shape

4 hardeners available with different reactivities: 25 min to 5 hours of pot-life

SD 815 B 1: Fast hardener, "rigid"
SD 815 B 2: Standard, rigidity between SD 815 B 1 and SD 815 B 3
SD 815 B 3: Slow hardener, very low modulus
SD 815 B 4: Ultra slow hardener

Applications

Parts under vibrations, shocks, low temperature
Flexible laminates: Body parts for cars, motorbike, 4X4
Casting and inclusion (degassing under vacuum)
Parts design, prototypes
