How to choose brightener for Waterborne Coatings

Water based coating is a new environmental protection coating in the current coating market. Compared with traditional solvent based coatings, water-based coatings have more advantages.

 

Water based coatings mainly use water as solvent, which can save a lot of resources in terms of cost. In addition, the water-based coating is also more convenient in the construction, which can be applied directly in the wet surface and humid environment, with good adaptability to the material surface and strong adhesion of the coating. Because of its good environmental protection, waterborne coatings are mostly used in interior decoration. The appearance is mainly white. However, the problem encountered by coating manufacturers is that the white brightness is not enough. Even if titanium dioxide is added, the effect is still not ideal.

 

The reason why the whiteness of titanium dioxide can not go up is that the whitening principle of titanium dioxide is physical covering, which is equivalent to the basic white and belongs to the filling type. If you want to be whiter and brighter on the basis of white, you need to add whitening agent, water-based paint fluorescent whitening agent.

 

As we all know, water-based coatings require safety and environmental protection, so the selection of fluorescent whitening agent is also a strict requirement. According to the characteristics of water-based coatings, Shanghai enmai recommends a fluorescent whitening agent apc-1 for liquid water-based coatings. The appearance of this brightener is milky white liquid, which has good dispersion effect in water-based coatings, and is acid and alkali resistant. There is no requirement for water quality in the production process of water-based coatings.

 

The fluorescent whitening agent apc-1 used in water-based coatings, only a small amount (2 / 10000), the white brightness of the coating will be improved, and good weather resistance, can prevent the aging of the coating.

 

If you are also a manufacturer of waterborne coatings, and you also encounter the problem of insufficient white brightness of products, welcome to Shanghai enmai. We provide you with sample trial service and technical guidance.
