Application

Used as main raw material in RTV mold silicone rubber, defoamer and silicone glass cement.
1. Used as insulating, moisture resistant, anti-shock and heat resistant perfusion sealing material in radio, electronic equipment, semiconductor and other electronic components and assemblies.

2. Used as rubber roller material in automobile and machinery industry.

3. Used as rubber roller material in textile, plastic and printing industry.
4. Caulking sealing material in construction industry.
5. It has excellent mold release performance, particularly suitable for the manufacture of precision mold and impression materials.

Usage and dosage
Generally use with curing agent to get crosslinking curing. Used in release paper, it need coupling agent to fix. The curing agent accounts 3 to 5 percent of the silicone glue and coupling agent accounts 0.5 to 1 percent.

Most of the cases the silicone glue are spread on surface of the base material after being mixed by curing agent and coupling agent in ten times dilution of dissolvent, then get solidified in ordinary temperature for over 30 minutes or by heated between 120°C and 150°C for 30 seconds. No dissolvent is needed in sealant and mould gum. Stir in mixture of curing agent (varies from single-component to double-component), and 30 to 120 minutes after deaeration it will solidify.
