Indispensable fluorescent brightener in paint

Fluorescent brightener is one of the chemical additives commonly used by many paint manufacturers. Its purpose is to improve the whiteness, brightness and brightness of paint. How can such a small chemical additive be favored by many paint manufacturers? Three points of enmai chemistry are summarized as follows

 

1、 Increased the whiteness of the paint

 

The charm of fluorescent whitening agent is mainly reflected in the whiteness. Most manufacturers have high requirements for the whiteness of paint. The whiteness of white paint is a very important selling point. After all, who will buy the white paint that does not look white? So for paint, whiteness is very important. Ordinary pigments can only make the paint achieve the effect of physical whitening. Although the whiteness of the paint is enough, the color is relatively dark, which also makes it difficult for people to have the desire to buy. The fluorescent whitening agent of optical whitening can make up for this defect. Through the optical principle, the blue purple fluorescence and the yellowish light in the paint complement each other to get white light, So that the naked eye to accept the white light source, this white light is not only bright and dynamic, but also can improve the customer's desire to buy.

 

2、 Increased the brightness of the paint

 

The function of fluorescent brightener is not only to increase the whiteness of the product, but also to increase the brightness of the product on the basis of whitening. The reason why the paint does not look good is that there is no brightness. The brightness produced by fluorescent whitening agent is very bright, mainly due to the high reflection coefficient. The light reflected by ordinary light will be received by the eyes, and then transmitted to the brain to respond. So fluorescent brightener is also slightly better in increasing brightness.

 

3、 Increase the weatherability of the paint

 

Weatherability, as the name suggests, is how long it will not react with the air after being oxidized in the wind and sun, resulting in hard to eliminate yellowing. In fact, this kind of yellowing is inevitable, because it will come into contact with the air and have oxidation reaction, but how to delay the oxidation reaction is the key link. All kinds of places will use paint, no matter which place can not avoid contact with the air, produce oxidation. So a lot of paint at the beginning of the effect is very good, but not for a long time, become dull, this is not the reason for the increase of fluorescent whitening agent. The paint added with fluorescent whitening agent will not appear yellowing for several years. This is the excellent performance of fluorescent whitening agent to improve the weatherability of paint, which can be improved by several grades compared with ordinary paint.
