Polyester resin base flame retardant adhesives
For fixing electronic devices, with outstanding electrical properties
-
Product name
SC608Z2 Series
-
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.
