Masil® XL 1Crosslinker

Clear liquid

MASIL XL-1 Crosslinker is a reactive silicone polymer containing silicon-hydride groups that has been specifically designed for use with MASIL SF 201 and MASIL SF 202 polymers to produce cured silicone elastomers. MASIL XL-1 Crosslinker will react with any vinyl-functional silicone polymer in the presence of a noble metal catalyst. MASIL XL-1 Crosslinker provides protection against moisture, dirt, and other environmental contaminants in electrical or electronic encapsulation applications.
