TECHSIL: Silicones

April 11, 2011

The new RTV191 range consists of UV-curing, solvent-free silicones that combine the quick curing speed of UV adhesives with the temperature resistance of silicone sealants. Portions directly exposed to UV rays cure in seconds, while other areas cure by moisture in the air without adding heat. After curing, the product becomes an elastic rubber that can be used on electronic assemblies for bonding, potting, sealing or coating. Typical uses include conformal coatings and the sealing of connectors.

The ability of this material to cure with both UV light and moisture mean that any portions in “shadow” will still cure. The resulting cured material reportedly remains elastomeric.
