The metal, PP, nylon and other materials in the surface coating spraying process, often there will be a problem: the poor adhesion of paint, 100 lattice, boiled and tested. In these cases, serious impact on the production schedule and the quality of products, paint and coating industry is a big trouble. So, the coating adhesion how do poor paint? Your free sample Dadong adhesion promoter!

The film is coated with adhesion to the substrate surface with degree of fastness together. This is the binding force from the polar group in polymer film (such as hydroxyl or carboxyl groups) and interaction between the coated surface of the polar group and the formation of the coated surfaces. The pollution or water; the film itself has a larger shrinkage stress; polymer crosslinking interaction during the curing process and the number of polar groups decreased. These are factors that lead to the adhesion of the film decreased. Increase the adhesion of the there are many methods (such as the collocation of different resins, processing on the substrate adding adhesion promoter etc.), which add adhesion an agent is a simple and efficient method. The adhesion promoter is in the paint industry to improve the performance of coating materials, coating adhesion enhancement is one of the most common methods in the firmness of the substrate has the advantages of convenient operation, the characteristics of significant effect.

The improvement of production technology, product quality requirements are increasingly high. Dadong resin chemical industry to develop their own brand fit, "Dadong resin", with the industry's attention to professional understanding, conform to the trend of energy-saving environmental protection products, and reduce the pollution of the environment, adhere to the "green" road. Taiwan Dadong resin for many years since, has been committed to the development, environmental protection, coating additives has wide applicability. The nylon treatment agent, PP treatment, TPU treatment, TR90 treatment agent, metal surface treatment agent, UV repair water. Help a lot of paint and coating customers to solve problems of various material adhesion.
