1、Check the test report. Qualified paint products will have a test report issued by a third-party testing agency. Consumers can ask for the test report from the merchant to check the two important environmental protection indicators of the paint, the content of free TDI and benzene. Free TDI is present Among the harmful substances in wood lacquer curing agents, benzene is also very toxic, which can cause leukemia, damage the human liver, and reduce human immunity. The less free TDI and benzene content, the higher the safety of the product.
2、Scratch surface. A good paint has high hardness, good scratch resistance, not easy to scratch, and can play a good role in protecting wood. Consumers can try to use nails or paper to scratch the surface of the sample back and forth. The surface of good paint is smooth and undamaged, while the paint with low hardness will have obvious fine scratches, which will affect the beauty and life of woodware.
3、Check transparency. Consumers observe the transparency of the model, the high-transparency paint has a beautiful luster, and can better highlight the natural texture of the wood. It can well modify the wood and make the wood more beautiful and beautiful. And those paint samples with white and misty surfaces must be inferior products.
4、Touch. Whether it's good paint or not, you can know by touching it. Good paints have a high solid content, feel plump and moist, delicate and smooth, while inferior paints have a low solid content, and the paint film still feels brittle and thin even if it is painted multiple times, and paints that contain impurities will have an obvious graininess.
5、Check yellowing resistance. Yellowing resistance is an important indicator of paint performance. Paints with poor yellowing resistance can cause discoloration and ageing of furniture. This is particularly evident in white paint and light-colored paint. In the two paints under strong ultraviolet radiation, the worse the paint, the faster it will turn yellow.
