Simple Three Step Identification of Environmental Protection Coatings

2021-05-09

With the change of the environment, the coating industry has carried out a series of reforms, especially the "oil to water" to make environmental protection coatings more widely used. However, what is environmental protection coating and how to define it?

For most consumers, the understanding of environmental protection is: no formaldehyde, benzene and other harmful substances; no heavy metals, no organic volatiles in the coating; no pungent smell in the coating. As for environmental protection coatings, MST coatings, with the concept of high quality, continuous innovation and environmental protection, gives a more comprehensive interpretation.

1) The raw materials used should be environmentally friendly
Whether the raw materials are environmentally friendly affects the final product performance. In the past, it was the world of paint, but now the market has become the world of "water-based". After all, "water-based" is the king. Why do we need to change oil into water? Because the paint needs to be diluted with organic solvents extracted from petroleum and coal, it not only needs to consume fossil energy, but also contains a lot of benzene, toluene, xylene, formaldehyde and other toxic and harmful substances. Because it is harmful, it should be changed.
But coatings are made up of resins, pigments, fillers, solvents and additives. Are some coatings inorganic? The answer is yes. For example, MST's coating products use pure inorganic raw materials, especially inorganic ceramic water paint, which has the characteristics of high hardness, high temperature resistance, etc. (the "high temperature resistance" determines that the pigments and fillers of this kind of coating must be inorganic, so it can be said that only this kind of coating can achieve the complete environmental protection of raw materials.)

2) Environmental protection in production process
The environmental protection of coating products can not prove that the coating is environmental protection, because in the process of coating production, such as: organic matter precipitation when resin chelates, dust pollution when preparing materials and mixing, cleaning waste discharge of production tools, etc., will pollute the environment.
It is difficult to achieve absolute environmental protection, but in the production process, it is the best way to ensure the environmental protection of the production process to use reasonable technology and environmental protection equipment for the treatment of dust, waste gas, waste liquid and waste. The environmental protection of raw materials can greatly reduce the environmental protection investment in this link, and it is easier to achieve environmental protection in the production process.

3) The final film should be environmentally friendly
Finally, the environmental protection of the paint film, which must be concerned about the environmental protection performance, whether the small molecules, solvents and other organic substances in the paint film volatilize completely in the drying process, whether the film contains heavy metals, whether the residue after the film falls will cause harm to human body due to inhalation or ingestion, etc.
Most water-based environmental protection coatings can protect the environmental protection of coatings film, while the environmental protection of oil-based coatings film is related to the raw materials, resin types, drying methods and dryness of coatings.

Each type of coating has the characteristics of each type of coating, so the selection of environmental protection coating must be combined with: raw materials, production process, environmental protection of paint film, application purpose, product certification, etc.
