Application of dioctyl ester plasticizer in coating products

Dioctyl ester plasticizer DOP is a widely used plasticizer product. The addition of plasticizer in the paint has a certain impact on many properties of the film, such as tensile strength, strength and toughness, elongation, permeability and adhesion. Depending on the type of base polymer and plasticizer, the effects on these properties are different.

Dioctyl ester plasticizer is one of the additives in paint production. It is very important to select the appropriate additives in the design of the formula. Dioctyl ester (DOP): its performance is similar to that of the dibutyl ester, but its volatility is small, and its light resistance and heat resistance are good. It is commonly used in nitrocellulose coatings and PVC plastisol and organic sol coatings.

The addition of plasticizer will increase the elongation of the film and reduce its tensile strength. In addition to influencing the mechanical properties of the film, the plasticizer will also affect some other properties of the film. Therefore, the appropriate amount of plasticizer should be determined based on the comprehensive balance of various factors.
