CWIEME SHANGHAI 2017: WACKER presents novel Silicone Resin for Vacuum Pressure Impregnation

SILRES^® H62 C is a solvent-free, liquid silicone resin which is cured by heat. As a methylphenylvinylhydrogen polysiloxane not modified with organic components, its volatile content is very low, making it especially suitable for VPI (Vacuum Pressure Impregnation). SILRES^® H62 C is usually cured between 170ºC – 200ºC without emitting any byproducts. With a RTI (Relative Thermal Index) of 25,000 h at 230ºC, it features excellent thermal stability. When cured, it can meet all the requirements of insulation classes H and C. Moreover, by virtue of its curing mechanism, SILRES^® H62 C cures to a tack-free film even in contact with air. Applied by VPI, this product can provide permanent protection to the windings of electrical motors, against moisture, dirt and temperature fluctuations. SILRES_® H62 C is used for impregnation in a wide range of industries and applications, including traction motors, electric drives, smoke-extraction motors, as well as generators and turbines.

ELASTOSIL^® RT 772 is a pourable, two-component silicone potting adhesive which cures rapidly at room temperature. UL 94HB listed when cured with Catalyst T 77, it features very good heat resistance and hence can withstand the high temperature of motor service environment over a long term. Furthermore, ELASTOSIL^® RT 772 offers good primerless adhesion. Its fast curing property also helps to improve the production efficiency. Especially suitable for glueing and sealing of metal and glass, ELASTOSIL^® RT 772 can be used to protect the insulation ring of electrical motors.
