What are the red pigments for color paste?
Color paste is made of pigment and other solvents according to a certain proportion of mixing, grinding and become, it is a semi-finished product of paint or coating, because it has the characteristics of easy to use, low cost in the case of less dosage, no dust pollution than color powder, so it has a great coloring status in the market, because the color powder can be used in both paint and ink, so the color paste is divided into the color paste for coating and paint and the color paste for ink, according to the different systems, the color paste is also divided into oil-based color paste and water-based color paste, so the pigment for color paste is also different. According to different system, color paste is divided into oil-based color paste and water-based color paste, so the pigment for color paste is also different, the following yellow pigment for color paste and red pigment for color paste to make an understanding.
First of all, pigments for color paste are divided into inorganic pigments and organic pigments. The difference between inorganic pigments and organic pigments will not be repeated here.
Red pigment for color paste has more color spectrums, complete, and more application fields, and the basic color is divided into six kinds: big red, purple red, bright red, magenta, deep purple red, peach red and pink. In the inorganic pigment system, iron oxide red is also a kind of red pigment for color paste. In the pigment paste for paint, due to most of the paint requirements for non-migration characteristics, the big red pigment is generally pigment red BBS, or permanent red F3RK, violet red color for sunlight-resistant red BBC, bright red color for permanent red F5RK, magenta color for pigment red 57:1, peach pink pigment for 122 # red, deep violet red color for sunlight-resistant violet red 2R, the above colors are commonly used in the general-purpose color paste pigment! The above colors are commonly used pigments in general-purpose color paste, but for the very special requirements of paints or printing ink, the red pigment used for color paste should be adopted as high-performance pigment. For the very special requirements of paints or inks, high performance pigments should be used for the color pastes. For example, the red pigments commonly used in water-based color pastes are: permanent red F3RK, permanent red F5RK and permanent red FGR.
Precautions for mixing color paste for water-based paint coating:
1, before using the color paste and paint mixing test, is to determine the color paste and paint mixing capacity, only does not return to the coarse and does not flocculate, can carry on the color mixing.
2, in order to avoid long storage time or contact with high temperature and other factors, resulting in uneven color paste, must be fully stirred before use.
3、Color paste should not be operated too fast when added to the stirred paint, otherwise it is easy to produce flocculation and other undesirable phenomena.
4, the color formula first do a small test, can avoid the color paste add too much, resulting in waste.
5、Use the whole barrel of color paste, must be sealed to avoid the remaining color paste is contaminated or due to moisture evaporation caused by the surface of the color paste crusting and dry cracking, affecting the next use.
Color paste is a semi-product made of pigment or pigment and filler dispersed in paint.
-Pure oil as the adhesive is called oily color paste. Resin color paste is called resin color paste when resin paint is used as adhesive.
The pigment and filler paste dispersed by adding surfactant with water as medium is called water-based color paste.
-Since there are many kinds of paints, there are also many kinds of color pastes. In order to make the pigment and so on better dispersed in the paint, often in the manufacturing process, add a small amount of surfactant, add zinc naphthenate and so on.

With the rapid development of construction and industry, including hotels, commercial, landscape, transportation and other color paste areas rarely designed to the field have been significantly into the development of the color paste market scope, is moving towards a holistic, energy-saving development trend, of course, this is mainly manifested in the rapid rise of the color paste manufacturers, driven by the entire color paste industry tends to be highly efficient, low-carbon development. As an important branch of the paint industry, water-based color paste in the industry, real estate, furniture, home appliances, building materials and home furnishings, driven by the rapid growth of mainstream consumption, water-based color paste in the modern home improvement, home decoration life plays an increasingly important role.
Water-based color paste is used for coloring, its application areas are very broad, including coatings, leather, printing, paper, latex, textile and other industries, the main service object is the coating industry.
