T300 Polyurea antiseptic coating

Product introduction polyaspartic polyurea

Steel structures such as petrochemical storage tanks, chemical pipelines, offshore oil platforms, and port engineering are exposed to harsh atmospheric corrosive environments and are subject to corrosion by corrosive factors such as moisture, oxygen, coastal salt spray, and chemical atmosphere in the atmosphere. Painting protection. The aliphatic polyurea anticorrosive coating of this product is an environmentally-friendly long-life heavy-duty anticorrosive coating developed in recent years. It has outstanding UV resistance and environmental protection. It is a high-solid and low-viscosity coating. The coating has high cross-linking density and shielding. It can effectively prevent the intrusion of corrosive factors in the environment, prolong the service life of the facility, and reduce the steel structure repair fees. polyaspartic vs polyurea

Performance characteristics polyaspartic coating

Using leading technology, high-performance aliphatic polyurea resin and aliphatic polyisocyanate are the main film-forming materials. The film-forming coating contains a large amount of urea bonds and a hydrogen bond structure, and has a high crosslinking density. These impart excellent barrier properties, abrasion resistance, chemical resistance, and UV resistance to the coating, and fully protect the metal structure from moisture and various external corrosion factors. The coating has a very high solid content, and can achieve zero VOC or very low VOC emission during the coating process. The required film thickness can be obtained in one construction, the construction efficiency is high, environmental protection and energy conservation. This product is suitable for the top coat layer of heavy-duty anti-corrosion coating. In addition to excellent protection performance, it also has ultra-long UV resistance (4000V resistance), and its UV resistance is comparable to that of fluorocarbon paint. More than traditional acrylic polyurethane (PU) coatings. Therefore, this type of coating has a wide range of applications in engineering vehicles, ships, wind power, hydraulic structures, offshore platforms and so on.
