WCNA-SILRESH62C
SILRES® H62 C is a liquid, solvent-free one-part heat-curing phenyl silicone resin formulation. The product is ideal to impregnate electrical coils of motors and generators. Besides SILRES® H62 C can be used to provide hydrophobic properties to porous materials and as binder for composites made of fibrous fillers, cloths, woven or non-woven reinforcing materials. The formulation is ready-to-use and crosslinks under heat. While curing SILRES® H62 C does not release chemical byproducts, and hence a curing shrink is barely noticeable. The product also thermosets in thick layers, even when in contact with air. Fully cured SILRES®
H62 C has excellent electrical insulation properties and outstanding long-term heat resistance. It additionally shows high stability against weathering, moisture and UV light, and it can therefore be exposed continuously to constantly changing climatic conditions or UV radiation.
