RubberMax® 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.
