Recently, the European Union issued an official authorization regulation, classifying titanium dioxide as a suspected carcinogen in Group 2 by inhalation based on EU Regulation (EC) No. 1272/2008 on the classification, labeling, and packaging (CLP) of substances and mixtures.
The curing temperature of various HAA curing agents varies, and the heat resistance of the cured material also varies greatly. Generally speaking, using curing agents with high curing temperatures can result in cured products with excellent heat resistance.
Since the emergence of powder coatings in the early 1970s, powder coatings have the advantages of being completely solvent-free, able to be completely converted into coatings, high coating efficiency, and good comprehensive performance in terms of protection and decoration
The powder coating made of pure polyester resin has the following characteristics: good weather resistance of the coating film, suitable for outdoor product coating; The heat resistance of the coating is good,
In recent years, powder coatings have been increasingly recognized by consumers as an environmentally friendly and pollution-free coating technology. Many developing countries, especially some emerging coating markets,
Firstly, due to the low toxicity of HAA, with the development of the economy and the increasing awareness of environmental protection, the widespread application of HAA in powder coatings will become inevitable.
Due to the strong toxicity of TGIC and its impact on the environment and human health, its application has long been resisted in many countries and regions around the world,
With the increasingly strict environmental requirements, powder coatings have developed rapidly due to their many advantages such as low pollution, high decorative value, and good comprehensive performance.
The powder coating and coating industry in China has developed with the rise of the domestic home appliance industry since its opening up. After more than 20 years of development, it has grown from scratch and made significant progress from small to large.
When curing resin products, it is often necessary to add fillers to the resin, stir evenly, and let it stand for a period of time. After that, a layer of transparent liquid will appear on the upper layer of the mixing bucket,
