RTV Adhesives and Sealants

Silicone rubber based RTV sealants / adhesives from United Adhesives Inc. provide strong bonding to most common plastics and metals with excellent thermal stress release and water resistance. Epoxy based sealants / adhesives provide strong structural bonding to most common plastics and metals with strong oil and chemical resistance. Some major features are like this:

-                Strong bonding to aluminum and most common plastics.

-                Thermal stress compliant with silicone RTV sealants.

-                Automated dispensable

-                Excellent moisture resistance from RTV silicone sealant

-                Excellent oil and chemical resistance from epoxy RTV

They are used to bond and seal electronic devices, components, equipment, connections, cover plates, housings, etc; make formed-in-place gaskets; assemble and repair electronic devices. They can also be applied as general-purpose sealants for other applications.
