The difference between water-based paint and oil-based paint, what about water-based paint?

Water-based paint and oil-based paint are both used in our lives. As a water-soluble paint, water-based paint is generally diluted with water and does not contain organic solvents. It also does not contain Toxic heavy metals, such as toluene, formaldehyde and other harmful substances, are relatively non-toxic and environmentally friendly. The main film-forming substance of oil-based paint is called dry oil, which is somewhat different from water-based paint. It generally contains a strong pungent smell, and often contains a large amount of harmful substances in the gas. So, what are the specific differences between the two? Let’s find out together.

Difference 1. The biggest difference is the diluent

The biggest difference between water-based paint and oil-based paint is the diluent. From the perspective of production raw materials, there is not much difference between water-based paint and oil-based paint. Agents are completely different.

Generally, we buy paint home and dilute it first before use. Traditional "paint" uses organic solvents as diluents, and special thinners need to be purchased separately. Therefore, this kind of paint is also called "oil-based paint". Water-based paint uses water as the diluent, that is, the paint can be used directly by adding water. This makes the construction of water-based paint more convenient and reduces the difficulty of operation.

In addition, using water as the diluent also greatly increases the environmental protection of the paint. Organic solvents are hazardous to a certain extent and can easily release harmful substances, such as benzene series, free TDI, etc. Water itself is non-toxic and harmless, which makes water-based paint a more advanced and environmentally friendly interior wall coating. Excellent water-based paint is dozens of times more environmentally friendly than traditional oil-based paint.

Difference 2. Water-based paint can only meet national standards.

Water-based paint is more environmentally friendly and more convenient than oil-based paint. In fact, home interior wall latex is currently available on the market. Paints are all water-based paints. As people pay more attention to environmental protection in decoration, the country's standards for wall coatings have become more stringent. The amount of harmful substances released by oil-based paint cannot meet the national standard requirements for home interior wall paint. Therefore, regular paint brands will only use water-based paint.

Water-based paint is more environmentally friendly, but it is not absolutely environmentally friendly and safe. Differences in materials, processes, equipment, and even brand manufacturers also give water-based paint different levels of environmental protection. The production process of paint is very simple, but some factories do not control the quality during the production process, which may lead to the addition of impurities and greatly reduce environmental protection.

Difference 3. Most furniture paints are “paints”

Except for interior wall paints, the most common paint for civilian use is wood paint. The so-called wood paint is the paint used on wooden furniture. Generally, the surface of wooden furniture needs to be coated with a topcoat to ensure its physical functions such as moisture-proof and mildew-proof, prolong its service life, and make it easier to take care of.

However, the current use of water-based paint on furniture is less than 5%. , This is due to cost considerations. The cost of water-based wood paint is higher than that of oil-based paint. In addition, the state's environmental protection requirements for wooden furniture are not as strict as interior wall coatings, and there are no relevant environmental protection requirements specifically for wooden furniture. Therefore, many companies prefer to produce oil-based paint due to cost considerations.

When it comes to the question of what is the difference between water-based paint and oil-based paint, in fact, the difference between the two is quite big. For example, the diluents used in the two are different, and the water-based paint that meets the national standards is water-based paint. Relatively speaking, water-based paint is more environmentally friendly and healthier than oil-based paint, but many furniture today still use oil-based paint, because the hardness, fullness and aging resistance of oil-based paint are often better than water-based paint. However, if water-based paint is used, for those who have higher requirements for home environment, they may need to renovate in three to five years.
