Neoprene Bonding Layer

UK Rubber Belting can provide a neoprene bonding layer on multiple types of rubber sheets including polymer-based and mining rubber sheets, as well as pulley lagging rubber sheets. We can provide a bespoke service for each client, depending on the application.

A neoprene bonding layer can be used in the aggregate and mining industries on all kinds of polymer-based rubber sheets. This process is used in various industries for bulk handling applications.

Among the benefits of neoprene is its excellent adhesion to metal. A thin layer of neoprene backing, normally between 0.8mm and 1mm thick, is added to the majority of the metal lining rubber sheeting.

Adding the neoprene bonding layer to metal is a relatively simple process, but one that must be carried out precisely to ensure an effective result: surfaces must be clean, dry and free from contamination, such as oil. Metal surface should be cleaned with a solvent, before being primed with metal primer and allowed to dry completely.

The glue mixture’s adhesive-to-hardener ratio is 100g to 5g. This is coated on the rubber and the metal plate and left to dry for 15 minutes, before both surfaces are pressed together.

Neoprene bonding layers are commonly used in rubber belting applications to extend the life of the shell. The bonding layer is designed so the belt can stretch and become longer lasting. Reducing the build-up of materials, while eradicating belt placement, it is resistant to adverse weather, temperature, radiation and more.

With high-strength, durable adhesion benefits, a neoprene bonding layer can be used with various metals.
