Effect of PP surface treatment agent in coating industry

  The purpose of PP surface treatment agent is to act as an auxiliary between PP substrate and paint
The PP surface treatment process is an important link in the PP plastic spraying process
The PP surface treatment agent is similar to the PP substrate system, so the two can achieve effective binding Because PP material has high crystallinity and strong impact resistance, it is widely used in the coating industry, mainly in the production of household appliances, small commodities, toys, etc Painting is one of the indispensable operations in the coating industry, because painting is to decorate the surface of products, which can not only enhance the product quality, but also make the appearance more attractive
The same is true of PP spray paint
The quality of spray paint directly affects the product quality
Products with excellent quality and certain attractiveness in appearance have a certain position in the market
However, there are some difficulties in painting the surface of PP material
Due to the low polarity of PP material, poor surface ability and poor adhesion with paint during spraying, the coating is prone to fall off, and the adhesion is a difficult problem Traditionally, corona treatment and surface polishing are used to change the molecular structure of PP surface, but these methods are complex, time-consuming, labor-intensive and unsafe
At present, the effective way to solve the adhesion of PP material is to use PP surface treatment agent
The birth of PP surface treatment agent has further improved the development of the coating industry
It is an auxiliary agent between the substrate and the paint layer, and the operation is simple and safe
Therefore, the coating industry is more acceptable
It is applicable to manual spraying or automatic line spraying respectively
The effect of improving the adhesion to solve the problem of paint falling is stable and obvious, and the adhesion test can reach 5B
