Product Description
Bectron® SK 75V1-35 / SH 79V2-35:
Bectron® SK 75V1-35 when mixed with Bectron® SH 79V2-35 will cure to a self-bonding silicone rubber in 1 hour at a temperature of 120°C . Elasticity and dielectric properties of the final rubber remain largely stable in a wide range of tempera- tures, between -40°C and +200°C.
Key Properties of Bectron® SK 75V1-35 / SH 79V2-35
- Addition cure system
- Good adhesion to various materials
- Low viscosity
- Good temperature cycling resistance
- UL 94 V0
Application Areas of Bectron® SK 75V1-35 / SH 79V2-35
- Thanks to its elastic properties and long term thermal resistance Bectron® SK 75V1-35 system is suc- cesfully used for encapsulation of pressure sensitive devices as well as for protection of motor windings in hot air systems.
- Additionally Bectron® SK 75V1-35 system is general- ly suited as a protection for electronic components and circuits such as as high-performance semi- conductors and high load resistors.
