Masil® SF 305

Clear liquid

MASIL SF 305 is a reactive silicone polymer containing silicon-hydride end groups that has been specifically designed for use with MASIL SF 201 and MASIL SF 202 polymers to produce cured silicone elastomers. MASIL SF 305 will react with any vinyl-functional silicone polymer in the presence of a noble metal catalyst. MASIL SF 305 provides extended chain lengths in silicone elastomers that provide protection against moisture, dirt, and other environmental contaminants in electrical or electronic encapsulation applications.
