Silicone rubber is used to bond the glass panel of induction cookers.
Silicone Rubber Analysis:
The introduction of phenyl groups improves the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups improves its temperature and oil resistance.
Silicone rubber has good low-temperature resistance, generally functioning at -55℃. With the introduction of phenyl groups, it can reach -73℃.
Silicone rubber also has outstanding heat resistance, capable of long-term operation at 180℃, and can withstand temperatures slightly above 200℃ for weeks or longer while remaining elastic. It can withstand instantaneous temperatures above 300℃.
Glass sealants are mainly divided into two categories: silicone sealants and polyurethane (PU) sealants. Silicone sealant-what we commonly call glass sealant-is further divided into acidic and neutral types (neutral sealants include: stone sealant, anti-mildew sealant, fire-retardant sealant, pipe sealant, etc.).
Precautions: Thoroughly clean metal and plastic surfaces to remove oil and grease. For plastics, rinse all surfaces with acetone first. For rubber surfaces, sand with sandpaper and then wipe with acetone. Follow the precautions for using acetone.
Apply silicone sealant evenly to the prepared surface. If bonding two surfaces, position one side first, then press the other side firmly to expel air, but be careful not to squeeze out the sealant. Place the bonded assembly at room temperature to allow the sealant to cure.
