About This Product

■Summary

More than half of plastic products are manufactured and processed using resins such as PP, which are difficult for paint to adhere to. In addition, in recent years, as engineering resins and rubber products with various functionalities have become popular, the demand for high-performance paints to decorate and add functionality to materials has also increased. Along with the development of such materials, various primer paints are being developed day by day, but selecting a primer is not easy as it is made of integral molding of metal and plastic, and a wide range of adhesion and stronger adhesion are required. "Multi Primer EXC-3000" is a primer for all types of materials that are difficult to adhere to, such as PP, elastomers, and metals.

■Features

・Excellent adhesion to materials that are difficult to adhere to, such as all grades of PP, nylon, engineering resins, and metals. ・Excellent interlayer adhesion with a wide range of two-component acrylic urethane topcoat paints ・Good workability because it is a one-liquid type

■Recommended thinner

No setting

■Applicable materials

・PP ・Nylon (nylon 6, RENY) ・Elastomer ・Aluminum (A1050P) ・Aluminum alloy (A5052P) ・Stainless steel (SUS-304) ・Galvanized iron plate

■Precautions for use

- If foreign substances such as mold release agents adhere to the material, it may cause poor adhesion or repellency, so please wash it before painting. ・Depending on the type of solvent, thinner may cause a decline in physical properties, so be sure to use a dedicated thinner. - Various grades of materials are available, and their properties may differ from the original, so please check before using. ・Be sure to stir evenly before use. When painting, put the diluted paint in a stirring tank and paint while stirring. - Avoid direct sunlight and store paint in a cool, dark place (0-40℃). - If the paint is stored in a low temperature environment (below 0℃), there is a risk that the paint will crystallize. In that case, please warm the paint or boil it in hot water (50-60℃ for 2 hours) before use.
