With the ever-increasing design life demands placed on traditionally available steel pipe coatings, the need arose for a radical departure from the known. This new coating would have to show dramatic increased performance.
SINTAKOTE II® was introduced into the South African market in the mid-90’s after enjoying considerable success in Australia, where it has become the preferred coating for steel pipelines in the water industry. Since then, what used to be a low-density polyethylene coating, has been replaced by a medium-density polyethylene coating SINTAKOTE II® offering greater advantages in corrosion protection.
Sintakote II® Fusion Bonded Medium-Density Polyethylene is applied directly to pipe using a fusion bonded process. It provides cost effective protection to pipes against mechanical damage, chemical and corrosion attack.
Outstanding features of SINTAKOTE II® include:

The process of applying Sintakote II® comprises thoroughly cleaning the bare steel pipe by shot blasting and then heating. Heated pipe is dipped into a fluidised bed of Sintakote II® powder which fuses onto the hot surface to a thickness of 1.6 mm – 2.3 mm, depending on the pipe size.
