Example of Pigment FAQs

What are some common additives for pigment powders?

1. Resin: Resin is one of the most common additives in pigments. It can improve the viscosity, fluidity, adhesion and wear resistance of pigments. Resin is divided into many categories. Commonly used resin includes acrylic resin, silicone resin, epoxy resin and the like. Among them, acrylic resin is often applied in high-speed printing and high-temperature baking varnish pigments due to chemical corrosion resistance and high-temperature deformation resistance.

2. Levelling agent: an additive that can improve the smoothness and wettability of pigment surfaces. Surface tension is likely to occur in the process of pigment preparation. It will result in wrinkles and bubbles on pigment surfaces and affect the quality of prints. The leveling agent can effectively reduce the surface tension, and improve the smoothness and wettability of pigment surfaces, thus making pigments stabler and smoother in the printing process.

3. Diluent: an additive that can reduce the viscosity of pigments and improve the fluidity and dilution of pigments. Generally, the use of diluent depends on specific pigment types and uses. Low-volatility diluents are applicable to easy-to-dry and low-viscosity pigments, such as xylene. High-viscosity pigments are applicable to highly volatile diluents, such as alcohols and ketones.

Anti-sticking agent: an additive that can prevent pigments from sticking and caking. If there is too much resin and pigments, sticking and caking will occur, affecting the quality of prints. The anti-sticking agent can effectively reduce the stickiness and viscosity of pigments, and thus prevent sticking and caking.

4. Anti-sticking agent: an additive that can prevent pigments from sticking and caking. If there is too much resin and pigments, sticking and caking will occur, affecting the quality of prints. The anti-sticking agent can effectively reduce the stickiness and viscosity of pigments, and thus prevent sticking and caking.

5. Dispersant: it is conducive to compounding of pigments and resin slurry.

6. Anti-settling agent: it can prevent paint pigments from settlement in the storage process.

7. Anti-sagging agent: it can prevent pigments from sagging in the brushing process.

What are some common mediums for pigment powders?

Common mediums in pigment powders includes water, grease, resin, organic solvents and so on.

What are some common binders for pigment？

1. Pigment powder materials

Pigment powders are common raw materials of pigments. They include iron oxide, titanium dioxide, carbon black, acrylic acid and chromic acid. Iron oxide is one of the most common pigment materials. It is suitable for production of pigments of various colors, including yellow, red, brown, black and orange pigments. Titanium dioxide is a common white pigment material. It is widely applicable to paint, ink, plastics, rubber, etc.

2. Pigment liquids

Pigment liquids are also common raw materials of pigments, including alcohols, esters and ketones. They can improve the viscosity and fluidity of pigments. They also affect the gloss and transparency of pigments. In addition, some organic pigments are suitable for production of ink and paint.

3. Pigment resins

Pigment resins are common pigment materials, including polyimides, polyurethanes and polypropylene. Production methods include chemical reaction and polymerization. Pigment resins can improve the hydrophilicity, adhesion and corrosion resistance of pigments. Some resins are suitable for production of pigments with high gloss and transparency.

What are the benefits of using pigments?

There are inorganic pigments and organic pigments, with the following advantages.

Advantages of organic pigments:

Bright and long-lasting color. Organic pigments have bright and long-lasting color for various materials.
High color stability and light resistance. Organic pigments have high color stability and light resistance. They can maintain the same color under a variety of conditions.
Safe, non-toxic and environmentally friendly. Production materials of organic pigments are organic compounds. Organic pigments are safe, non-toxic, environmentally friendly. They do no harm to the human body and environment.
Various colors. Organic pigments have a variety of colors to meet different needs, including red, yellow, blue and green.

Advantages of inorganic pigments

High dispersibility

The relative density of inorganic pigments is high, usually 3.5-5.0. With the high density and small specific surface area, inorganic pigments are easy to disperse in plastic. Inorganic pigments have low coloring power. They will have bright colors if the concentration is high.

High covering power

The covering power refers to the ability of a pigment to make the product opaque. It is expressed by the minimum amount of pigment required to fully cover the black and white grids of the substrate. The covering power of pigments varies with particle size. Inorganic pigments have high relative density and large particle size. The inorganic pigments of Hunan Nuoli have high covering power.

Excellent weather resistance and light resistance

The weather resistance and light resistance of pigments in plastic directly affect their value. The colors of inorganic pigments often become darker but not fade in the sunlight and atmosphere. The colors of other pigments fade due to changes in chemical composition and structural damage in the sunlight and atmosphere. In general, inorganic pigments have better weather resistance and light resistance than ordinary organic pigments.

Excellent heat resistance

Except chrome pigments, most inorganic pigments have high heat resistance, especially those produced by calcination at high temperatures. As the calcination temperature is 700-1,000℃, inorganic pigments have excellent heat resistance. Lead-chromium inorganic pigments have poor heat resistance and light resistance. Chromium yellow is coated in surface treatment abroad to greatly improve the heat resistance.

Excellent chemical stability

Most inorganic pigments are inert. They have excellent resistance to acids, alkalis, salts, corrosive gases and solvents. However, some pigments may react with other substances. For example, ultramarine is not chemically acid-resistant. Iron yellow is more alkali-resistant than chromium yellow.

What is pigment used for?

Industrial pigments

Industrial pigments are applicable to industrial products. They have visible colors in industrial production. They are for product marks, anti-corrosion coatings and vehicle paints. Typically, industrial pigments are a mixture of complexing agents, solvents and pigments. They may be organic or inorganic pigments. They have excellent light resistance and maintainability. They are also suitable for pharmaceutical manufacturing, printing and coatings.

Artistic pigments

Artistic pigments are applicable to the creation and painting of art works. They are usually of high quality. Their quality depends on the types and manufacturers. Artists often use pigments as needed to achieve ideal effects. Artistic pigments have a variety of colors. Common sources include plants, animals or chemical synthesis.

Cultural pigments

Cultural pigments are for cultural purposes, such as bacons, paints, and brushes. In Asian countries, they are often for art purposes, such as calligraphy, painting and engraving. Cultural pigments are mostly natural pigments from plants, animals and chemicals.

Household pigments

Household pigments are for various daily applications, such as home decoration, hair dyeing, cosmetics, toys and food dyeing. They are usually natural or man-made for colors and entertainment in life.

Do pigments have a shelf life?

Pigments vary in the shelf life. The shelf life of most pigments is 3-5 years. For example, the shelf life of gouache pigments is about 5 years. Pigments are for coloring objects. They include inorganic and organic pigments, or soluble and insoluble pigments. Major applications include ink, paint, plastic products, printing and dyeing, paper, rubber products, ceramics, etc.

How is pigment different from dye?

In terms of differences from pigments, dyes are organic compounds that can dye fibers or other substrates into certain colors. Primary applications of dyes include fabric dyeing and printing. Most dyes are soluble in water or will be soluble after appropriate chemical treatment. Some dyes are insoluble in water but are soluble in alcohol and oil. They are applicable to coloring of oil wax, plastics and the like. Pigments are greatly different from dyes. They are organic or inorganic color compounds, insoluble in water and common organic solvents. Not all color substances are organic pigments. Color substances must have the following features for applications as pigments:

Bright color to ensure a solid color on objects (or substrates).
Insoluble in water, organic solvents or mediums used.
Easy to evenly disperse, and able to maintain the inherent crystal structure, free from physical and chemical effects of the medium used.
Resistance to sunlight, weather, heat, acid, alkali and organic solvents.

Compared with dyes, organic pigments are different in applications. The conventional application of dyes is textile dying, while that of pigments is non-textile coloring (such as ink, paint, coating, plastic and rubber). This is because dyes have affinity (or substantivity) to textiles and can be adsorbed and fixed by fiber molecules. Pigments have no affinity to coloring targets. The binding between pigments and coloring targets depends on film forming substances such as resins and adhesives. Dyes are first dissolved in the medium used. In the dying process, even disperse dyes or VAT dyes undergo a process from crystal dissolving in water into molecules to dying of fibers.

Therefore, the color of the dye itself is not the same as that in fabric. Pigments are insoluble in the medium, so the original crystal structure remains unchanged, and the color of the pigment itself is the same as that in substrates. Accordingly, the crystal structure is important for pigments but not for dyes. In other words, the crystal structures of dyes are not closely related to dyeing effects. Although dyes and pigments are different from each other, both of them are applicable under special circumstances. For example, some anthraquinone VAT dyes are insoluble but can be used as pigments after pigmentation, Such dyes are called pigment dyes or dye pigments.

Are there eco-friendly pigment?

Although pigments have some environmental problems, rational use of pigments and environmentally friendly materials can reduce the environmental impact.

Extraction with environmentally friendly materials

In the pigment production process, extraction with environmentally friendly materials can significantly reduce the environmental impact. For example, some natural organic materials such as potatoes, yams, sunflower seeds and cassava are suitable for pigment production. They have excellent environmental performance.

Rational use

Low-carbon and low-emission applications of pigments can reduce environmental pollution. In addition, pigments with high quality and little environmental impact are beneficial for the environment.
