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.

Do you choose the right antioxidants to increase the heat aging resistance of materials?

As is known to all, when plastic products are exposed to outdoor sunlight, the strong UV light will produce different degrees of damage to the polymer materials.

UV absorber is an essential additive for plastics. It belongs to light stabilizer, which produces a stabilizing effect by absorbing and transforming the destructive UV light in the sunlight. UV absorber is mainly used in plastic products, such as plate, cable, pipe and other thick products.

PC transparent panels with light weight, impact resistance and other outstanding characteristics, as an environment-friendly plastic sheet with excellent comprehensive performance, it has gradually become a widely used plastic building material in the world. It is widely used in greenhouse/industrial plants, advertising signs, parking shed, agricultural greenhouse and other fields.

There are many factors affecting the weathering resistance of paint film in paint industry, among which sunlight radiation and oxygen in the atmosphere are the main factors affecting the aging of paint film.

Omnistab UV1 is a highly effective liquid UV absorber, which can effectively absorb ultraviolet light from 240-330nm, and absorb almost all of it in the waveband of 300-330nm.
