Mining & Aggregate Rubber
Neoprene Bonding Layer

RM Biltrite™ RubberMax™ Neoprene Bonding Layer is used for a variety of purposes in the mining and aggregate industries. It can be securely applied to all types of polymer-based rubber sheets, including RM Biltrite™ mining rubber sheets and RM Biltrite™ pulley lagging rubber sheets. Neoprene rubber has inherently excellent metal adhesion qualities. It is usually applied in a thin layer onto the back side of metal-lining rubber sheets in order to create a firm connection. Optional neoprene bonding layers are available on all RM Biltrite™ mining rubber products upon request.

Adhesion Directions

  • Thoroughly clean & dry surface from oil, paint, and other contaminants.
  • If applying to metal surface, clean first with solvent
  • After surface is prepared, apply metal primer
  • Allow primer to dry completely for at least 1 hour, depending on atmospheric conditions
  • Cut 5 test pieces 11.8" x 1.18" (300mm by 30mm) from rubber sample. Condition pieces at room temperature for 24 hours.
  • Prepare glue mixture by using an adhesive to hardener ratio of 3.5 oz to 0.18 oz (100gm to 5gm)
  • Coat rubber test strips with glue on the bonding layer side and on the metal plate. Allow to dry for 15 minutes
  • Mount rubber test strips onto the glued metal plate and press together
  • Check bonding strength by pulling rubber strips by hand
