Techsils RTV191 Range are UV-curing, solvent free silicones which combine the quick curing speed of UV adhesives with the excellent temperature resistance of silicone sealants.

Portions directly exposed to UV rays cure in seconds whilst other areas cure by moisture in the air without adding heat. After curing, the product becomes an elastic rubber which can be used on electronic assemblies for bonding, potting, sealing or coating. Typical uses include conformal coatings and sealing of connectors.

The ability of this material to cure with both UV light and moisture mean that any portions in shadowwill still cure. The resulting cured material remains elastomeric meaning that it stays flexible giving good protection from vibrations.

The main component of the RTV191 range is silicone resin resulting in good elasticity and excellent resistance to heat, cold and moisture. A range of viscosities, including gels offer customer tailored solutions.
