ST-2 high-efficiency optical brightener agent can be dispersed in soft water at any time. Its acid and alkali resistance is pH=6～11. It can be used in the same bath as anionic surfactant or dye, nonionic surfactant and hydrogen peroxide. It is incompatible with organic salts in coatings. It is easy to migrate and yellow when the coating is dry. ST-2 effectively solves the weather resistance and migration resistance of the coating, and can keep the coating as long as new after construction.
Water-based paint products for acrylic latex paint, acrylic water and polyurethane synthetic waterborne wood paint, polyurethane water paint, real stone paint, waterproof paint, colorful paint, dry mortar, dry powder putty, construction glue, water-based color paste, etc. The amount of addition is small, and the whitening and brightening effect is excellent!
According to the different processes of the coating, there are three ways to add the optical brightener agent: 1. The optical brightener agent is added in the color slurry grinding process (ie, the preparation process of the color paste), and then fully ground until the particles are evenly dispersed to less than 20um. In the paint. 2. After the optical brightener agent is ground fine, it is added to the coating through a high speed disperser. 3. In the production process, the optical brightener agent is dissolved with a mixture of water and ethanol of about 80-40 degrees of warm water, and then added to the aqueous coating, and then uniformly stirred and dispersed uniformly. The amount added is 0.05-0.1% of the coating.
