As is known to all, light stabilizers are essential modifiers for polymer materials, which could absorb ultraviolet energy and delay the photoaging of polymer material.

UV resistance treatment finish is an essential part of textile functional finish. At present, the market prospects of textiles with uv resistance are very broad, and the varieties of uv resistance fabrics are increasingly extensive.

Generally, the white products obtained by traditional process (such as bleaching, adding blue) will not be very ideal whiteness, even a little yellow.It feels like the product is not brand new. Why this happening?

OMNISTAB® UV1130 is a light yellow liquid UV absorber, belonging to the benzotriazole series. Benzotriazole UV absorbers can strongly absorb 310-385nm UV light.

The adhesives used by human beings in the early days came from natural materials, such as animal and plant adhesives, and most of them were water-soluble. However, with the development of modern industry after the 20th century, both the output and performance of natural adhesives can not meet the requirements.

As people's health and environmental protection consciousness are gradually enhanced, people are advocating the use of novel Green Sustainable Painting. Among them, waterborne sustainable paintings become ine of the crucial R&D direction in the 21st century. This kind of coating can greatly reduce the harm to the environment and human, its most outstanding characteristic is that it without volatile organic compounds (VOC) and harmful air pollutants (HAP).

Polyurethane material are widely used in all industry area because of its excellent properties, such as fiber, PU leather, foaming material and artificial leather etc. However, like most polymer materials, polyurethane is prone to photo-oxidative aging phenomena such as yellowing, cracking and degradation of mechanical properties in the process of outdoor use. In the process of aging, polyurethane materials will be accompanied by yellowing.

Ultraviolet absorber is one of the important varieties of polymer additives, according to the chemical structure and mechanism of action, it is divided into Benzophenone, Salicylate, Triazine and benzotriazole and so on.
