What is the difference between water-based car paint and oil-based car auto paint?

1. Compared with environmental protection and health, water-based paint has an absolute advantage

(1) Environmental protection:

Since water-based paint uses water as a diluting solvent, it has an ultra-low VOC content (below the national mandatory standard of 200mg/L), and is a truly non-toxic, odorless, high-tech and environmentally friendly product. Oil-based paints use organic solvents (banana water, thinner) as diluents, and their products contain benzene, toluene, xylene and their derivatives. In addition, polyester paints also use curing agents (including TDI), so poly The toxicity of ester paint is the highest, while the toxicity of nitro paint is the second.

(2) Flammability:

Water-based paint uses water instead of organic solvents, and its products are safe and non-flammable. The risk factors and troubles in the production and circulation links are greatly reduced. The oil-based paint contains benzene, xylene, acetone, solvent gasoline, and thinner are all highly flammable items.
2. Quality and performance comparison, the overall performance is the same

(1) Hardness:

Due to the use of advanced water-based acrylic synthesis system, the water-based paint can reach the physical index of 2H when the paint film is completely dry; ordinary polyurethane paint uses the addition of organic curing agent (TDI), so ordinary polyester paint is used The hardness of the paint film is the highest;

(2) Wear-resistant, yellowing-resistant, durable:

High-end water-based paint adopts advanced film-forming technology to make the surface of the paint film hard, wear-resistant and flexible, and will not turn white due to collision; it is not easy to yellow and has super long outdoor durability.


Specifically, compared with oil-based automotive paint, water-based Automotive Paint can greatly reduce the emission of organic solvents in the application, can reduce the amount of paint by as much as 2/3, and can reduce the amount of paint per vehicle in the production process of vehicle coating. The average amount of heat consumed by baking is more than 40%, which greatly reduces the energy consumed in the automobile production process. In addition, water-based automotive paint also has the advantages of good leveling of the paint surface, no waviness, bright color of the paint surface, strong paint surface hardness, excellent scratch resistance, and excellent weather resistance. Most mainstream automobile companies in Europe, the United States, and Japan use water-based automotive paint systems.

When repairing water-based car paint, you can use a special water-based car repair paint. This paint is designed for repair shops and has the characteristics of curing at room temperature or low temperature (generally below 60 degrees). There is no difficulty in using it in painting factories. On the contrary, it can also solve the problem of reducing the long-term inhalation of toxic organic solvents in large quantities by painters at work.
