alternative to PVC coating plastisol
alternative to PVC coating plastisol
(OP)
Hi there,
I am looking for an alternative plastisol to replace current PVC for coating the galvanized pipes. The pipes will go underground so the coating need to withstand soil chemical errosion, should have certain toughness to withstand impact in transpotation and handling, and need to have good adhesion to galvanized pipes.
I know there are powder materials, but I need plastiso for existing line.
Thanks,
Gao

There are polyolefins used in this type of application, look for Flame Spray of polyolefins, it is used on pipes all the time.
It basically take a polyolefin powder and conveys it through a nozzle, the powder passes through a flame that melts the powder. The powder hits the surface and re-solidifies.
