Metallic pigment paste is usually suspended in A81 resin and is used to create metallic finish in coatings. The way these pigments function is by scattering light, thus making them look like thin metal flakes. These are visible pigments and reflect light and create a finish that looks like a metal coat.
Mica pigment paste delivers a shimmer effect due to its ability to refract and reflect light. Mica is a mineral that undergoes peeling to give thin translucent flakes that are ground to a fine powder. When blended into resin, it gives a pearlescent effect that is commonly used in decorative coatings.
Tinter pigments are pastes or suspensions in resins that are used to slightly modify the color in paints, coatings and sealants. Usually added in small quantities, tinter pigments allow for formulation of multiple shades without significantly altering the base resin properties.
Like mica, luster pigments come from mineral sources and are intended for glossy, luminous finishes. Luster pigments are often used for effect pigments in coatings with color and metallic sheen.
Lacquer pigments are finely ground, colorant substances added to resin in paint or coatings. These don't include any binders and are based on resin types like phenolic and may be added to other bases like nitrocellulose lacquer.
These pigments are derived from natural sources like plants, insects or minerals. These are usually color powders or that have been ground up. Organic pigments are known to produce more vivid and brighter colors. They are also more translucent and less resistant to weathering than inorganic pigments.
Inorganic pigments are chemical compounds that are not formed from carbon-based molecules. Primarily formed from minerals, these pigments include materials like black iron oxide and titanium pigment paste. While they don't produce colors as bright as organic pigments, they are more stable in resin systems that require high durability like exterior coatings.
The A81 pigment paste is used in automotive coatings that require both durability and aesthetic appeal. Mica pigment paste enhances the aesthetics by providing multiple hues and effects like a metallic sheen while the A81 resin contributes to the sturdiness that is required in automotive coatings.
It is also used in architectural coatings typically used in residential and commercial buildings. In such a case, mica pigment paste may be used for the decorative aspect to give a gloss finish and luminescent effect. The A81 resin guarantees the paint remains durable and weather resistant, hence preserving the long-lived appeal in both interior and exterior settings.
In the automotive industry, the plastic parts used may have A81 resin added to them in the form of pigment paste for paint jobs. The resin provides protection in automotive interior plastics like dashboards, door handles, etc. This is due to the high amount of temperature and other environmental elements that car interiors get exposed to.
In electronics, plastics may be coated with pigment paste resin to protect electronic housings and components. A81 resin makes the pigment paste protective against other chemicals as well as UV light, thus preventing electronic parts from damage and prolonging the efficacy of the electronic devices.
Just like in paint and coatings, pigment paste resin can also be used in glue and sealants. The A81 resin acts as a protective layer by preventing moisture, hence protecting wood from rotting. When A81 is combined with other colorants like tinter pigment paste, they can be used in sealants for a more aesthetically pleasing finish. These sealants may be used in construction and plumbing applications.
In textile printing, Lacquer pigments may be used to produce high quality, vivid colors. The A81 resin in the pigment paste ensures that the colors obtained are fast and resist any adverse effects of chemical or physical elements in the environment.
Lacquer pigment paste has several materials that are responsible for the different properties and applications of the pigment paste. These include an acrylic copolymer resin that provides adhesion, flexibility and durability. The other is the pigment and colorant that provide the base colors and hues and may include tinter pigment paste among others. Solvents are included to dissolve and adjust viscosity while ensure effective mixing and application.
The pigment paste has a density range of 1.2 to 1.4 grams per cubic centimeter. It has solid content of 60 to 85% and typically contains no more than 1% water by volume. The A81 resin is temperature resistant of up to 100 degrees Celsius and has a glass transition temperature of - 50 degrees celsius.
Before application, the surface to be coated with pigment paste resin should first be prepared. The surface should be cleaned and made smooth for better adhesion of the pigment paste. The A81 resin and pigment paste have to be thoroughly mixed and blended until a uniform dispersal is achieved throughout the mixture.
The mixture is then applied onto the desired surface using different desired techniques depending on the end use. These application techniques include spraying, brushing, etching and screen printing among others. Once applied, the coating is left to dry at room temperature. However, to enhance the drying process, expose the coating to heat and increase the rate of curing of the resin.
In maintenance, the color splotch that is pigmented in the resin may be wiped with a damp soft cloth or sponge. Harsh chemicals should not be used on the resin as they may cause damage. Also, avoid exposure to a-l lot of water as this may undermine the integrity of the resin. Repair of pigment paste resin can be done by either applying new resin or a patch. The area of repair should be cleaned and prepared the same way as a new application.
When buying pigment paste resin, it is important to first consider the type of pigments that are present in it. Inorganic pigments give a better opacity and are more resistant to harsh chemicals and UV rays. They are therefore more ideal for external applications. On the other hand, organic pigments are suited for internal applications where a better color intensity and freedom are required.
The type of resin is also important when making a purchase. Unsaturated polyester resin, for example, is suitable for producing high performance containing superior surface qualities and chemical resistance. Similarly, epoxy resin provides excellent adhesion and moisture tolerance, making it ideal for electrical and electronic devices.
It is also important to consider the pigments contained in the pigment paste. Micron pigments will scatter more light and give a metallic finer appearance in paint or coating. Moreover, resin that contains A81 is more adaptable in use as it can be blended with other resins to achieve desired mechanical properties that are beneficial for different applications.
The hardware store where the resin will be bought from should be considered. Avoid stores that sell counterfeit products and high prices for low-quality products. Buy from stores that have been reviewed positively by other customers and have a variety of pigment paste resins available for selection. Another consideration is the price of the pigment paste resin. Fortunately, this resin is available at relatively affordable prices.
A1: The pigment paste resin may be harmful if inhaled or ingested. It's also harmful when absorbed through the skin. It may cause irritation to the nose, throat and lungs and may be harmful to the central nervous system. It may also cause skin irritation and is a possible carcinogen. Therefore, when applying the pigment paste resin, be sure to wear protective equipment.
A2: Yes. Some pigments have fine particle size that allow them to settle easily and go unnoticed. When they settle, only a clear layer of resin remains on top. Therefore, they have to be stirred frequently during use to keep them suspended in the liquid resin. This also ensures even distribution throughout the mixture for consistent color and texture in the final product.
A3: As long as food safe colorants are used and the resin is mixed and cured solidly, the painted items should be food safe. The items should also be sealed with a food safe sealer for added safety. Use pigments that have been identified to meet food contact safety standards and exhibit non-toxicity when ingested.
A4: The pigment paste resin should be stored in an airtight container to prevent moisture and air contamination. These two elements can cause the resin to thicken or cure prematurely. Store in a cool place away from direct sunlight to avoid degradation of the resin components that may be caused by UV light exposure. Generally, the storage conditions should be oriented to those that would maintain the quality and extend the shelf life of the pigment paste resin.
