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
This method
is utilized and preferred by Stingray.
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.
