Fast-curing 2K PU enables efficient pipe coating

A high-quality coating technology was requested that helped to expand the infrastructure quickly and reliably.

Ease of application and fast-curing properties were important requirements for the coating technology chosen for the project. Moreover, high mechanical resistance was crucial, given the long transit journeys to the site for the coated pipes.

Polyurethane technology based on Desmodur® and Desmophen® was chosen for this project to coat the internal surface of the pipes. “The ease of application and the fast-curing properties at ambient temperature made polyurethane a perfect choice for this project,” said Al Ezzi Ahmed, Production Manager at SADIP, the coating manufacturer which is part of the Amiantit Group. Another important benefit of the polyurethane technology based on Desmodur® and Desmophen® was the optimum balance between flexibility and tensile strength. The aim was to deliver coated pipes in very good condition to the site about 500 km away from the factory. “We had very few cracks and damage during transportation and installation of the pipes, which significantly reduced the amount of repair work,” said Raed Roustom, General Manager of the contractor NassTech.
