Application and advantages of water-based coating wetting agents

Water-based coating wetting agents play an important role in water-based coatings. Their applications and advantages are as follows:

Application

Improve fluidity and wetting ability: 

Adding an appropriate amount of wetting agent to water-based coatings can significantly improve the fluidity of the coating and its ability to wet the substrate, help reduce surface tension and accelerate the diffusion rate of the liquid on the solid surface, making the brushing more uniform and easy to operate.

Enhance wettability and dispersion stability: 

By adding appropriate wetting agent ingredients, the contact angle between the interfaces can be effectively reduced, the spreading area of the liquid can be increased, and the wetting degree of the coating can be increased. At the same time, the wetting agent can also prevent the agglomeration of pigment particles, maintain the stability of the system, and ensure good construction effects.

Prevent surface defects: 

In water-based industrial coatings, due to the high surface tension of the coating itself and the complex and diverse industrial construction substrates, surface defects caused by insufficient wetting of the paint film and the substrate are prone to occur. As one of the important additives for surface control, the substrate wetting agent can be used in water-based industrial coatings to prevent surface defects caused by poor wetting of the coating substrate, such as shrinkage, edge shrinkage, oil shrinkage, etc.

Advantages

Improve coating quality and durability: 

Using coatings containing high-quality wetting agents can improve the density and continuity of the paint film, effectively avoid problems such as pinholes and pores, improve the gloss and smoothness of the overall coating, extend the service life and improve weather resistance and other characteristics.

Environmentally friendly and safe: 

Most water-based coating wetting agents are made of environmentally friendly raw materials, have a low VOC (volatile organic compound) content, are harmless to the human body, have little impact on the environment, and are in line with the development trend of modern green chemical industry.

Promote film-forming efficiency and reduce cost investment: 

High-quality wetting agents can help form a uniform film structure, shorten drying time, speed up the production process, thereby improving work efficiency and saving costs for enterprises.

Strong compounding performance: 

Water-based wetting agents can be used in combination with other types of surfactants, and can be stable in ordinary, acidic, salty and hard water environments, and have a wide range of applications.

Improve gloss: 

Water-based wetting agents show excellent color paste wetting agent performance in water-based systems, good gloss, and effectively overcome the shortcomings of paint floating color and blooming.
