Differences between water-based and oil-based automotive coatings
1、 Compared to environmental protection and health, water-based paint has absolute advantages
(1) Environmental friendliness:
Due to the fact that water-based paint uses water as a diluent solvent and has an ultra-low VOC content (lower than the mandatory national standard of 200mg/L), it is a truly non-toxic and odorless high-tech environmental protection product. Oily paint uses organic solvents (banana water, Tianna water) as diluents, and its products contain benzene, toluene, xylene, and their derivatives. In addition, polyester paint also requires the use of curing agents (including TDI), so the toxicity of polyester paint is the highest, followed by the toxicity of nitrocellulose paint.
(2) Flammability:
The water-based paint uses water instead of organic solvents, and its products have the characteristics of safety and non flammability. Greatly reducing the risk factors and troubles in production and circulation processes. The presence of benzene, xylene, acetone, solvent gasoline, and thinner in oily paint is classified as highly flammable.
2、 Quality and function comparison, inductive function equivalence
(1) Hardness:
Due to the use of advanced water-based acrylic acid synthesis system, water-based paint can achieve a physical target of 2H when the paint film is completely dry; Due to the use of organic curing agent (TDI) in general polyurethane paint, the film hardness of general polyester paint is the highest;
(2) Wear resistance, yellowing resistance, durability:
High end water-based paint adopts advanced film forming technology, making the surface of the paint film hard, wear-resistant, flexible, and not white due to collision; And it is not prone to yellowing, with an ultra long outdoor durability function.
