SWD969 Metallic anticorrosion coatings – SWD Detail:

Product application scope

Anti corrosion protection of petroleum, chemical, transportation, construction, electric power and other industrial enterprises, especially storage tanks, chemical equipment, steel structures, embedded parts (including conductive type), roofs and walls of production workshops and storage rooms.

Product features and advantages

*Excellent corrosion resistance, thin coating can also play the role of thick film coating.

With excellent adhesion and low surface treatment requirements, it can be directly applied to the surface of metal workpieces, which not only has the effect of primer, but also has the function of top coating.

The coating is dense and tough, which can resist cyclic stress damage. Excellent mechanical properties, wear resistance, impact resistance and scratch resistance. Excellent anti-corrosion performance, resistant to erosion and damage of a variety of chemical corrosion media, such as salt spray, acid rain, etc. Excellent aging resistance, no crack and no pulverization for outdoor use. The coating can reflect light and heat in the sun to achieve the effect of cooling and energy saving. It has the ability of conducting to prevent static electricity from gathering. One component material, hand applied coating is convenient to use and can be applied in a variety of application modes.
