Completed Bonding Application

Application Situation
The newly fabricated caisson clamp needs to be sheathed with a corrugated neoprene rubber, and it must be bonded to the clamp using a tougher bonding material with a required 1.5 mm thick bonding line.
Application Method
The application was done using a stiff bristled brush in accordance with Belzona System Leaflet SHM-12.

Using a dummy pipe with the same diameter as the actual pipe, the corrugated neoprene rubber sheet was bonded in a sandwich between the clamp and the dummy pipe by tightening the bolts.
Belzona Facts
Belzona 2111 (D & A Hi-Build Elastomer) can be used as rebuilding and adhesive for elastomeric and non elastomeric substrates. Easy to apply without any hot work for bonding.

Belzona 2921 (Elastomer GP Conditioner) is a surface conditioner which is the elastomeric primer required for better adhesion of Belzona elastomers onto any rigid and flexible substrates.
