Waterborne coatings, as its name implies, are coatings that use water as a solvent. The production of coatings in China is growing rapidly. Due to the environmental protection policy in recent years, the economic type of waterborne coatings has begun to appear. However, many manufacturers of water-based coatings are faced with the problem that the whiteness of the products produced is not enough, and the color is not bright enough. Is there an additive that can improve the appearance of waterborne coatings? The answer is yes. Fluorescent whitening agent of waterborne coatings can solve this problem.
With the rapid growth of China’s economy, people’s awareness of environmental protection has gradually increased, and the requirements for coatings are also more environmentally sound. Therefore, the birth of waterborne coatings has been favored by many consumers, which has also promoted the rapid development of waterborne coatings industry.
Many manufacturers have seen the broad prospects of water-based coatings and have invested heavily in production. However, there are many manufacturers, and the competition is relatively fierce. In order to make their products stand out from many manufacturers, the coatings produced must have sufficient advantages, not only in price, but also in product quality and appearance.
There are also many water-based whitening agents in the market, most of which are used in washing, printing and dyeing, coating and other industries. Some of them are low-end. When they are added, the proportion is relatively large, with several kilograms added per ton. Moreover, the weather resistance is not very good, and yellowing is easy to occur.
According to the performance characteristics of water-based coatings, Shandong Jubang has a water-based paint fluorescent whitening agent ST-2, which is an milky white liquid, mainly suitable for whitening coatings, coatings, paints, inks, etc. of various processes using water as the solvent. It can be used in the same bath with anionic surfactants or dyes, non-ionic surfactants, hydrogen peroxide. The water-based paint added with fluorescent whitening agent ST-2 can make the white paint whiter and the light color more colorful, and can improve the weather resistance of the paint. Long term use will not cause color fading.
Waterborne paint whitening agent ST-2 has several advantages:
1. Highly concentrated water-soluble liquid with good dispersibility;
2. The whiteness is high, and the whitening effect is more than five times that of the traditional fluorescent whitening agent;
3. High weather resistance, good stability, high intensity of UV absorption capacity, making the product bright and white as new for a long time;
4. ST-2 whitening agent can withstand (high) temperature to more than 180 degrees, and will not appear yellowing when used in water-based baking paint, so that the paint will not precipitate.
