Dalian High Corrosion Resistant Coating Selection Guide: Performance Parameters and Scene Adaptation Points.

In the fields of industrial manufacturing, building protection, etc., high corrosion resistant coatings are a key defense line to resist environmental erosion and extend equipment service life. But in the face of a dazzling array of painted products, how to accurately select based on performance parameters and application scenarios has become the core issue in ensuring protective effects.

When choosing Dalian high anti-corrosion coating, performance parameters are the primary consideration criteria. The anti-corrosion level is the core indicator, and the common ISO 12944 standard classifies environmental corrosiveness into categories such as C1 to C5. For example, coastal areas or chemical plants need to choose coatings with C5-M (marine environment) or C5-I (industrial environment) levels. In addition, the adhesion of the coating determines its ability to resist peeling, which can be determined through grid testing; The weather resistance and chemical resistance should refer to the test reports of the product in environments such as ultraviolet radiation, acid and alkali.

 

Scene adaptation cannot be ignored either. In marine engineering, seawater salinity and high humidity can easily cause corrosion. Therefore, a matching system of epoxy zinc rich primer and polyurethane topcoat should be selected to achieve long-term protection by utilizing the sacrificial anode protection principle of zinc powder and the weather resistance of polyurethane; Chemical storage tanks require acid and alkali resistant ethylene based heavy-duty anti-corrosion coatings to ensure that the coating does not peel off or penetrate under strong chemical media erosion; Building steel structures are exposed to atmospheric environments for a long time, and fluorocarbon coatings with strong adhesion and good decorative properties can be selected to balance corrosion resistance and aesthetics.

In addition, construction techniques are also important reference factors. Partial painting requires high-temperature curing or special spraying equipment. If site conditions are limited, products with room temperature curing and easy construction should be preferred. Only by considering comprehensive performance parameters and scene requirements can suitable high corrosion resistant coatings be selected to provide reliable protection for equipment and buildings.
