What are the main components of silicone pigments?
Silicone pigments are silicone color pastes. Their main components include pigments, carriers, dispersants and various additives. The following is an introduction for you:
Pigments: This is the key substance that gives silicone color, which is divided into organic and inorganic types.
Organic pigments: bright colors and strong coloring power, such as phthalocyanine blue, azo red, etc. This type of pigment is often used in silicone products that require high color brightness, such as toys, accessories, etc. However, the light resistance and heat resistance of some organic pigments are relatively weak.
Inorganic pigments: have excellent light resistance, heat resistance and chemical stability, and strong hiding power, such as iron oxide series (iron red, iron yellow, etc.), titanium dioxide (titanium dioxide, which can whiten and improve hiding power). Commonly used in outdoor products, industrial products and other silicone products with high durability requirements.
Carrier: The main function is to carry and disperse the pigment so that the pigment can be evenly distributed in the silicone. Common ones are:
Silicone oil: has good fluidity and chemical stability, can make the pigment evenly dispersed, reduce the viscosity of the color paste, and facilitate processing operations.
Silicone rubber: The same base material as silicone products, good compatibility, can ensure better fusion of color paste and silicone, and improve product quality.
Dispersant: used to reduce the surface tension between pigment particles, prevent pigment agglomeration, and promote its uniform dispersion in the carrier. Common dispersants include various surfactants, high molecular polymers, etc. By adsorbing on the surface of pigment particles, changing the charge distribution on the surface of particles or forming steric hindrance, the pigment particles are kept in a stable dispersed state.
Additives: According to different performance requirements, some special additives will also be added:
Antioxidant: Prevent silicone from aging and discoloring due to oxidation during processing and use, and extend the service life of the product.
Light stabilizer: Improve the resistance of silicone to ultraviolet rays, reduce color changes and performance degradation caused by light, and is suitable for silicone products used outdoors.
Leveling agent: Improve the leveling performance of silicone, make the surface of the product smoother and flatter, and reduce surface defects.
Plasticizer: Increase the flexibility and plasticity of silicone, making it easier to process and shape.
