Water-based color paste Knowledge analysis
In home life, many colorful items we see are decorated with color paste, which is a kind of pigment concentrate that is obtained by surface treatment, surface wrapping and other technical processing of different pigments. Water-based color paste is one type of color paste.
1. The emergence of color paste
Traditional paints have many shortcomings, such as uneven coloring, relatively coarse pigment particles, inability to produce a smooth and delicate texture, easy fading, powdering, large pollution, etc. Through continuous improvement, coatings have developed in the direction of low toxicity and low pollution, and the current color paste has emerged. Color paste is a semi-finished product formed by pigments or pigments and fillers dispersed in paint. There are many classifications. It embellishes our lives, from clothing to home construction.
Color paste can be divided into water-based color paste, oil-based color paste, water-oil general color paste, etc. according to different solvents;
Color paste can be divided into paint paste, tape paste, paper paste, textile paste, mechanical paste, toy paste, latex product paste, etc. according to different uses.
2. What is water-based color paste?
Compared to oil-based colorants, most of the solvents in water-based colorants are water. It is a pigment dispersion and is the main coloring material for water-based plastics. Water-based colorants are more environmentally friendly than oil-based colorants. It has good coloring properties and is widely used in hotels, transportation, home furnishings, etc. It currently mainly serves the coating industry.
3. What are the main components of water-based color paste?
The main components of water-based color paste are generally composed of water, powdery pigments (toners), organic solvents, surfactants, moisturizers, etc. When necessary, some additives may be added to improve performance. Toner is the key component of color paste and one of the most toxic components. Different additives are generally highly volatile. Organic solvents are generally benzene, formaldehyde, etc., which also contain toxicity.
4. Why choose water-based color paste?
High-quality water-based colorants are well compatible with water-based polymer latex and exhibit a uniform texture. It has good light resistance, weather resistance, chemical corrosion resistance, and UV resistance; the finished water-based color paste has strong tinting power and high fluidity; it can be stored for a long time, is not easy to agglomerate and form sediments, and will not air-dry; it has stable properties , stable viscosity, not prone to foaming, not prone to mold, etc., and low VOC index. With so many excellent properties, water-based color pastes are becoming more and more versatile. It also plays a role that cannot be ignored in home decoration.
