Low temperature varnish

Low temperature varnish

VGE-7031 insulating varnish adhesive has good electrical conductivity and bonding properties, combined with its chemical properties and good saturation characteristics, making it an excellent low-temperature material。As an adhesive, the VGE-7031 can bond a variety of materials with short cycle times and can be air-dried or baked。Laminating is excellent for many materials and can be baked immediately after application to bonded parts, or baked and air dried after parts are assembled or stored for a few hours, days or 7 weeks。It is also an insulating adhesive at low temperatures and is commonly used as a adhesive for sensors。
