Physical Properties

Application

• SiSiB® LR9199 is widely used in LED lighting encapsulantion, power supplies, sensors, industrial controls, transformers, amplifiers, high voltage resistors, relays and solar cell encapsulation.

• Silicone encapsulation materials usually require a primer in applications where bonding is required. Primer should be applied in a very thin, even coat and then wiped off after application. Apply silicone elastomer after the primer has fully cured.

• SiSiB® LR9199 silicone encapsulants may be either room temperature (25°C/77°F) or heat cured. Room temperature cure encapsulants may also be heat accelerated for faster cure.

• The curing reaction begins during the mixing process. Initially, curing is manifested by a gradual increase in viscosity, followed by gelation and conversion to a solid elastomer. Tools for taking components A and B should be separated or wiped clean before use to avoid mixing the two components and causing local agglomeration and inability to use them normally.

• At 25°C, the safe storage period of A/B after full mixing is 1 day. The higher the temperature, the shorter the storage time.

• When using, avoid contact between rubber and compounds containing N, S, P and Sn elements, otherwise it will cause insufficient or incomplete vulcanization.

• The optimal ratio of components A/B is 1:1. Too large or too small ratio will affect the final performance effect of the product.
