Bectron® SK 75V2-35 when mixed with. Bectron® SH 79V5-35 will cure at room temperature to form a resilient elastomer in about 12 hours. Cure can be accelerated with heat. Elasticity and dielectric prop- erties of the final gel remain largely stable in a wide range of temperatures, between -50°C and +180°C. A 1:1 mixing ratio allows easy and safe processing of the system.
FEATURES
- Addition cure system
- Curing at Room Temperature
- Long working time
- Cure can be accelerated with heat
- Long term thermal resistance
- Elasticity
- Low hardness
APPLICATIONS
Bectron® SK 75V2-35 cross-linked with Elan-tron® SK 79V5-35 is specifically designed for protection of elec- tronic parts and components against high tempera- tures. Possibility of accelerated cure at high tempera- tures allows use in mass production manufacturing lines.
