Water-based paint is mainly based on water as the carrier, and then add pigment, toner, titanium dioxide, dispersant, fluorescent whitening agent and other raw materials. Most water-based paint manufacturers know that fluorescent brighteners are added for whitening and brightening of water-based paints during production, so how should the optical brighteners used in water-based paints be selected?

Water-based paint can be divided into acrylic resin type and polyurethane resin type, but no matter which type, optical brighteners  can be added for whitening. As the name implies, water-based paint uses water as a solvent. At this time, the solvent-based whitening agent is definitely Is inappropriate.


According to the performance characteristics of water-based coatings and the country's strict environmental protection requirements for coatings, we Raytop Chemical recommends the use of optical brighteners VBL, which is also water solved,We recommend the addition amount of five to one thousandth. Compared with water-based paint manufacturers, the cost will not increase much, but the brightness of the product can be improved a lot.
