Properties
This product is used at room temperature to within 280℃, can degrade 80 times of soft water, acid and alkali resistance is pH = 6~11, it can be used in the same bath with anionic surfactants or dyes, non-ionic surfactants, and hydrogen peroxide. In the case of the same dosage, the whiteness is 3-5 times higher than that of VBL and DMS, and the alignment energy is almost the same as that of VBL and DMS. , The paint is easy to migrate and yellow after drying. This product effectively solves the temperature resistance, weather resistance, yellowing resistance and migration resistance of the fluorescent whitening agent in water-based paints and water-based paints. It can keep the paint and white after paint construction. The degree is lasting as new.
Applications
Used for acrylic latex paint, acrylic and polyurethane synthetic water-based wood paint, polyurethane water-based paint, real stone paint, waterproof coating, colorful paint, dry powder mortar, dry powder putty, construction glue, water-based color paste and other water-based coating products with various process formulations, Small addition amount, excellent whitening and brightening effect! At present, it is a high-efficiency fluorescent brightener that is most suitable for water-based paints and lacquers at home and abroad.
Instructions
According to different coating processes, there are three ways to add fluorescent whitening agent:
1. The fluorescent whitening agent is added as a powder product in the color paste grinding process (that is, the color paste preparation process), and then it is fully ground until the particles are less than 20um uniformly dispersed in the paint.
2. After grinding the fluorescent whitening agent finely, add it to the paint via a high-speed disperser.
3. In the production process, dissolve the fluorescent whitening agent with a mixture of about 30-40 degrees of warm water and 1/80 of water and ethanol, then add it to the water-based paint, and then disperse it evenly by fully stirring. The addition amount is 0.02-0.05% of the weight of the coating.
