  SWD961 Series SH138 room temperature cure water

    base system ship cabin internal environment friendly

special iron oxide red anticorrosion primer

Descriptions               Ship painting operation goes through the whole process of ship construction. when usually applies with welding construction, the most commonly anticorrosion coating which is oil base, so large amounts of solvent will be volatized then cause to fires accidents in slightest negligence. After years of scientific research, SWD Urethane Co., USA developed water base ship internal cabine special iron oxide red anticorrosion protective primer. It is a new environment friendly green coating product can be safely painted in the case of normal ship construction.

Characteristics           Through special precision formulation and scientific process this primer takes environment friendly water base high molecule polymer resin and high-quality iron oxide red as main raw material. the primer is dense, with good plugging performance and penetrate resistance and excellent performance of salt water resistance, wet resistance, oil resistance, rust resistance and anticorrosion. High adhesive strength on the metal substrate, good bond strength with the following coating, the water base primer is easy to use, without pollution in and after application.
