Electrical properties of adhesive base material

It has electrical insulation properties and low dielectric properties comparable to epoxy resin and silicone rubber.
Therefore, it is used as an electrical insulating material for potting electrical components such as automobiles and motorcycles, coating printed circuit boards, impregnating and potting transformers, coils, and capacitors, and sealing cable joints.

Insulating waterproof material for electronic boards and electronic components

Electrical properties

Hydroxyl Terminated Poly butadiene™ cured products have excellent electrical insulation properties.
