Water-based paint VS oil paint
Comparison of quality and performance:
1, hardness:
Water-based paint adopts advanced water-based synthetic system, which can reach the physical index of 2H when the paint film is completely dry. Ordinary polyurethane paint uses ordinary polyester paint because it uses organic curing agent (TDI). The hardness of the paint film is the highest; while the lacquer (oil paint) requires many times of painting, and the hardness of the paint film is poor!
2, feel:
Fullness: The effect of polyester paint on the feel and fullness of the paint film is the best, while the feel and fullness of the paint film of the nitrocellulose paint is not very good.
3, wear resistance, yellowing resistance, durability:
The surface of the paint film is hard, wear-resistant and flexible, and will not turn white due to collision; and it does not yellow, the paint film remains clear and transparent over the years; and the long outdoor durability can be achieved. Oil paints have the disadvantage of being easy to collide and turn white, easy to yellow, and unable to maintain the effect for a long time.
Comparison of environmental protection and health:
1. Environmental protection:
Because water-based paint is a dilution solvent with water and an ultra-low VOC content (below the national mandatory standard of 200mg/L), it is a truly non-toxic and tasteless high-tech environmentally friendly product. The oil paint uses organic solvent (banana water, water of the day) as a diluent, and its product contains benzene, toluene, xylene and its derivatives, and polyester paint also uses a curing agent (including TDI), so polyester The toxicity of the paint is the highest, while the toxicity of the nitrocellulose paint is second.
2. Flammability:
Water-based paints use water instead of organic solvents, and their products are safe and non-flammable. Greatly reduce the risk factors and troubles in production and use. Oil paints contain benzene, xylene, acetone, solvent gasoline, and natural water, all of which are highly flammable.
3. Stimulating odor:
Water-based paints use water instead of organic solvents, and their products do not produce any irritating odor when applied. Oil paints contain organic solvents, which are volatilized into the air during brushing and drying, directly stimulating the body's sensory organs.
4, after the paint check-in time:
The water-based wood lacquer is environmentally safe and safe because it is non-toxic and tasteless; Oil paints, because their organic solvents will volatilize harmful gases during the drying process, generally can not be directly after the completion of coating, need to wait for a period of isolation.
Exterior
Water-based paint: Since it does not contain harmful substances, it will not volatilize into the air, so there will be no defects such as yellowing, and it will last longer.
Oily paint: harmful substances are continuously released and long-acting volatilization, so it is easy to yellow, and the durability is not good.
Water-based paint: The new generation of PU water-based paint products are not inferior to oil-based paints, whether it is fullness, hardness or scratch resistance. It can also be used to make high-grade furniture that cannot be achieved by oil paint. Effect
Oily paint: The quality of the paint film is good, but the paint film is harder and more brittle, and it is not easy to repair after damage.
store
Water-based paint: non-flammable.
Oily paint: extremely flammable.
Repairability:
Wooden doors painted with water-based paint, furniture, can be directly covered when repairing; while wood-based furniture with oil-based paint, when repairing, you must first use sandpaper to polish the old paint film before you can paint Go up.
Construction performance:
Water-based paint: no special requirements, after simple training, it can be painted, it is very convenient for you to brush and repair yourself.
Oily paint: it must be professionally trained and practiced before it can be painted. Due to its strong professionalism, it is difficult for ordinary people to brush well.
