   SWD952 Series SH109 One component

hand brushable polyurea

    metal structure anticorrosion protective coating

 ­­­

Descriptions                 Over the last decade, spay polyurea elastomer has been widely applied in various filed of model industry for its excellent physical performance and stable chemical media resistance. However, the environment ambient of temperature above 120℃ and strong corrosion conditions will influence the performance of two components polyurea. In order to solve this problem, SWD Urethane Co., USA developed one component hand brushable metal structure anticorrosion protective coating. This coating product can be last long applied in the environment of high temperature 180℃ or 50% sulfuric acid consistence. With high anticorrosion and temperature variation performance, it has been rapidly spread to many heavy duty anticorrosion fields such as petroleum and chemical industry.

Characteristics              The coating is cured by absorption and reaction with air moisture, with high adhesive strength on metal substrate. The presence of large amount of urea bond, biuret bond, urethane bond and hydrogen bond makes it to be excellent in the properties of mechanism and anticorrosion performance, with high performances of acid resistance, alkali resistance, salt resistance, water resistance, temperature variation and chemical resistance. The one component products can be brushed, roller or spray and just open for paint, without special spray equipment.
