ELASTOSIL® RT 722 RB A/B
- Chemical Family
- Silicones
ELASTOSIL® RT 722 RB A/B is a thixotropic, two-component silicone sealing adhesive that cures to an elastomer through thermal curing. It is specifically designed for various sealing applications. This product is well-suited for use as a sealing adhesive for electronic control units, as well as for FIPG (formed-in-place gasket) applications in plastic and metal housings. It can also be used as a dam material for dam-and-fill applications and for sealing and gasketing of housings.
