Polyester paints will need to be used in many places in our lives, but many people have to say what it is and relatively difficult. Polyester paint is an indispensable material for modern decoration. It is environmentally friendly and safe. It is not only vivid in color, but also is not easy to wrinkle and fall off. It is a decorative paint that everyone loves very much. Here we will specifically introduce what are the advantages and disadvantages of polyester paint , and the difference between water paint and polyester paint. 
What are the advantages and disadvantages of polyester paint?
1, advantages
Since polyester lacquer entered our China, it replaced the varnish at the fastest speed and became the most important paint in our furniture. The advantages of polyester paint are many, not only the color is very rich, but also the thickness of the paint film, spray two or three times, and can completely cover the material of the base layer, so do furniture can directly paint polyester paint on the density board. The demand for grass-roots materials is not high. The paint film of polyester paint has excellent overall performance. Because of the use of curing agent, the hardness of the paint film is higher, hard and wear-resistant, rich in richness, hot and humid resistance, dry heat, acid and alkali oils, solvents and various chemicals. High insulation. The varnish has light color, high transparency and gloss, good gloss and color retention, and has good protection and decorative properties. 
2. Disadvantages
However, the only major drawback of polyester paint is that it is relatively cumbersome to deploy, and the accelerators and initiators used have very strict requirements on the dosage. The activation period after the lacquer is short, must be completed within 20 to 40 minutes, otherwise it will be gelled and scrapped, so it is necessary to match the use, how much with how much, and its repair performance is also poor, the damage of the paint film after the patch . Polyester paints need to be cured during the construction process. The amount of these curing agents accounts for one third of the total amount of paint. These curing agents are also called hardeners and their main component is TDI. These TDIs that are in the free state will turn yellow, which will not only make the furniture painted yellow, but also make the adjacent walls yellow. This is a major drawback of polyester paint. 
The difference between water paint and polyester paint
1. Now we come to understand the difference between the two kinds of paints. First of all, our water-based paint is actually made of clear water as the diluent, which does not contain organic solvents such as benzene and xylene, and paint products that do not require curing agents. Environmental protection and no harm to human health is the biggest feature of water-based paints. At present, most of the domestic products are traditional paints, and organic solvents are used as thinners for paints. Many products advertise that environmental protection does not contain harmful substances, but products need to be diluted with organic solvents before they can be used in a ratio of 3:1 or 2:1.
2. In fact, the organic solvent we just mentioned is banana water. The liquid also contains a large amount of benzene and formaldehyde organic compounds. These are harmful to our body and are the enemy of good health. Slow, long-term harm to the human body. The oil paint itself also contains a large amount of organic matter, its VOC content can reach more than 500, and using water as a diluent, the product's own VOC content is very low in the basic 50. It can reach the level of wall paint, and because it is diluted with water and does not contain any harmful substances, it can be brushed and lived. It is completely harmless to the human body. 
3, now in European countries have realized the harm of paint, so it will completely ban a series of oil paint, it is generally water-based paint can be sold and used in civilian areas. Domestically, due to technical problems and the market's demand for low-end prices, most of them still use oil-based paints. It is believed that in the near future, water-based paints will increasingly enter people's lives.
What are the advantages and disadvantages of the above polyester lacquer , and the differences between the water borne lacquer and the polyester lacquer are introduced here, I hope this helps everyone.
