What's the difference between water-based pigments and oily pigments? What are their advantages and disadvantages?

First, their respective advantages and disadvantages:

1, water-based pigment:

Its advantages are reduced VOC emission, safety, no fire hazard, construction in humid environment, convenient cleaning and so on. The disadvantage is that the difference between dry and wet painting is obvious. Overlapping brush strokes will cause messy pictures, dark paper, easy to be destroyed by microorganisms when forming films, and long drying time, especially in low temperature and high humidity environment.

2. Oily pigments:

Its advantages are easy production, low price, good paintability, flexible coating and good permeability. Its disadvantage is that oily pigment has a strong pungent smell, which is unbearable, and the gas also contains a lot of harmful substances, which is harmful to human health.

2. Composition difference:

1, water-based pigment:

Water-based polymer is used as film-forming substance, and water is mainly used as solvent.

2. Oily pigments

: Also known as grease paint. A coating with drying oil as the main film-forming substance mainly includes clear oil, thick paint, oily ready mixed paint, oily antirust paint, putty and putty. The main oils used are tung oil, linseed oil, stillingia oil, soybean oil, sunflower oil and fish oil.

3. Environmental protection:

1, water-based pigment:

With the characteristics of non-toxic and pollution-free, it is gradually loved by consumers, and oily coatings will be basically banned in the future. Waterborne coatings do not contain harmful carcinogens in use, and are non-toxic and tasteless, so there is no need to worry about the taste after brushing.

2, oily paint:

It contains a strong irritating smell, which is unbearable. The gas also contains a lot of harmful substances, which is harmful to human health. After brushing for a month or two, the strong pungent smell is basically volatile and tasteless. But a small amount of toxic gas will be released for several years.
