Four types of coating additives

What is the paint additive? Paint additives are paint additives which are special additives used to improve product quality and performance in the paint production process. Then the following small series will lead everyone to understand.
  What are the paint additives?

   Modern paint additives can be divided into four types:

  1) Additives that act on the paint production process, such as defoamers, wetting agents, dispersants, emulsifiers, etc.

  2) Additives that act on the coating storage process, such as anti-skinning agents, anti-settling agents, and the like.

  3) Additives that act on the film formation process of the coating, such as drier, curing agent, leveling agent, anti-sagging agent, etc.

  4) Additives that act on the film properties, such as plasticizers, flatting agents, mildew inhibitors, flame retardants, antistatic agents, ultraviolet light absorbers, and the like.

  Classification of coating auxiliaries


   as the name implies, driers The effect is a substance that allows the coating film formed after the coating to be quickly dried and agglomerated. The most significant effect is that the time it takes to dry the agglomerates of the oil film formed by the coating is rapidly reduced from a few days to a few hours. This is important for customers who have a requirement for construction time. At the same time, rapid drying of the conjunctiva can also prevent contamination of the coating film. A commonly used drier is a naphthenic acid soap.


   This is what we call plasticizers. Its role is to increase the toughness of the film. The most widely used toughening agent is DEHP. The Chinese name is phthalic acid.


   Coatings are often liquid, and have a low consistency and a high fluidity. When a thickener is used, the consistency of the coating will increase significantly and the fluidity will be significantly reduced, which will make it easier to use the coating to prevent the coating from flowing around and reducing losses. There are many types of thickeners, and there are white carbon black thickeners, hydrogenated castor oil thickeners, and metal soap materials which can be used in coatings.

   Paint additives are widely used in many industries, including a large number of architectural coatings, automotive coatings, marine coatings, protective coatings, and coil coatings. China’s paint manufacturers are continually increasing investment and adjusting production processes, which has greatly stimulated the demand for domestic and foreign coating additives market.
