In the architectural decoration and furniture manufacturing industries, coatings have played a role in beautification, protection and corrosion protection. Water-based coatings and solvent-based coatings are two common types of coatings. This article will introduce the difference between water-based coatings and solvent-based coatings and the advantages of water-based coatings.

water-based coatings, as the name suggests, is a coating with water as a diluent. Compared with traditional solvent-based coatings, water-based coatings have the following important differences.

environmental protection, water-based coatings reduce environmental pollution. Solvent-based coatings usually contain a large amount of organic solvents, which will evaporate into the air, cause pollution to the environment, and may form the ozone layer. Water-based coatings use water as a diluent, reducing the use of organic solvents, and will not produce harmful gases, more environmentally friendly.

construction, water-based coatings more convenient. Compared with solvent based coatings, the drying speed of water-based coatings is faster, which can reduce the coating cycle and improve the construction efficiency. In addition, there is no need to use organic solvents for cleaning after the construction of water-based coatings, which is easier to clean and reduces the time and cost of cleaning.

again, the use of safety, waterborne coatings more secure. The organic solvents in solvent-based coatings are highly volatile, which can easily cause dizziness, vomiting and other uncomfortable symptoms, and there is a risk of fire and explosion. The water thinner in the water-based paint is non-toxic and harmless to the human body, and it is safer and more reliable when used.

In addition, water-based coatings also have the following advantages in the use process. The color choice of

water-based paint is more diverse. In traditional solvent-based coatings, limited by the chemical properties of organic solvents, color selection is limited. The water-based paint uses a novel pigment technology, which can obtain richer colors and textures to meet the needs of different consumers.

water-based coatings have good adhesion and durability. After drying, the water-based coating can form a strong bond with the base layer, and has good weather resistance and durability. It can maintain a long service life under the influence of the external environment and effectively protect the coated object.

again, water-based paint does not contain harmful substances. Organic solvents in solvent-based coatings may release harmful chemicals that are potentially harmful to human health. The water-based paint uses environmentally friendly water thinner, does not contain harmful substances such as volatile organic compounds and heavy metals, and has less pollution to the human body and indoor air.

To sum up, there are obvious differences between water-based coatings and solvent-based coatings in terms of environmental protection, construction convenience, use safety, color selection and durability. In the context of the increasing awareness of environmental protection, waterborne coatings, as an environmentally friendly, safe and easy-to-use coating, have been widely recognized and applied. In the future, with the development of science and technology, water-based coatings will be more innovative and improved, bringing more benefits to the architectural decoration and furniture manufacturing industries.
