Heat Cure Adhesives & Sealants - Non-Sag (Thixotropic)

United Adhesives' heat cure non-sag (thixotropic) version adhesives and sealants made from high performance silicones and epoxies provide following major features:

-                Strong bonding to aluminum and most common metals.

-                Strong bonding to most common plastics.

-                Thermal stress compliant with silicone adhesives.

-                Automated dispensable

-                Non-corrosion sealants and adhesives

-                Excellent moisture, oil and chemical resistance

They are used to bond and seal electronic devices, components, electrical equipment, power and control connections, cover plates, housings, etc. The silicone series, Bondseal, provides stress release and resistance to high temperature and humidity. The epoxy series provides strong structural bonding for vibration applications and resistance to oil and chemicals.
