Description             

Gas &oil pipelines usually go through the complex geological structure and changeable climate zones. The geological structure changes caused by different climate, soil corrosion as well as the displacement and deformation will greatly damage the buried pipelines. SWD709 pipeline special spray polyurethane coating has excellent comprehensive physical performance and stable anticorrosion properties which have gained attention from the designers and applicators and been increasingly used in projects of buried pipelines. SWD Urethane Co., developed buried pipeline special polyurethane rigid coating in the 1970s and it has been successfully applied in American regions.

                                                                               

Characteristics              

It is high reactiverapid curingable to spray forming on any bending slope and vertical surface without saggingThe coating membrane is dense and flexible, insensitive to moisture and temperature, high adhesion to substrate and cathodic disbondment resistant. It has excellent properties of impact and wear resistance, stable chemical resistance to acid, alkali and salt, well protection from erosion of microorganism and plant roots, no cracking and peeling after long-term application.
