X-21-5249 is 50% of a Trimethylsiloxysilicate film former that is dissolved in Cyclopentasiloxane, a volatile oil that evaporates to leave behind a film. X-21-5249 forms a non-glossy, durable film that is of medium hardness.

X-21-5249 is a Trimethylsiloxysilicate film former that is made using partially cross-linked silicones. It contains 50% film former dissolved in Cyclopentasiloxane, a volatile oil that evaporates to leave behind a film that can improve water repellency and resistance to sebum. X-21-5249 forms a non-glossy, durable film that is of medium hardness. X-21-5249 has a viscosity of 60 mm2/s, specific gravity 1.034 (at 25 °C) and refractive index 1.404 (at 25 °C).

Chemical Description: Trimethylsiloxysilicate, Cyclopentasiloxane
