BONDING METHOD

PVC

There are two methods used to manufacture PVC pontoons:

  1. Glue
    • The best glue for this purpose is two part PU heat reactivated glue. The life expectancy of the glue and PVC pontoon are approx 10 years. Please note that PVC pontoons are not suitable for extreme cold or extreme hot condition like the tropics. Due to the glue being heat reactivated, glue failure in the tropics and extreme heat may occur unless steps are taken to manage pressure/heat.
  2. Heat Welding
    • The PVC is thermo welded using a special thermo welding machine.

HYPALON

Hypalon is a synthetic rubber and can only be glued. The glue is very specialized and unlike the glue used on PVC is not heat reactivated. The glue can withstand extreme cold and hot conditions. This is the choice of Military and Rescue organizations.
