Product name

 SC608Z2 series

Suitable use

 For fixing electronic devices and insulation

Features
  • An excellent electrical insulator.
  • Highly viscous and thixotropic, the product can be easily applied to a vertical surface without threading that may lead to an untidy appearance.
  • SC608LVZ2 is identical to SC608Z2 except for a lower viscosity.
