SILIBASE SILICONE produce Dispersion Stability
Jan 3, 2025
Dispersants, as an important functional additive, provide efficient solutions for various particle dispersion needs. Whether in industrial manufacturing or daily life, it demonstrates irreplaceable value. With the continuous advancement of technology and the strengthening of environmental awareness, dispersants will play a role in more fields, providing support for the sustainable development of the industry.
Application fields of dispersants
Coatings and inks
The main function of dispersants in coatings and inks is to disperse pigments, fillers, and auxiliary particles, ensuring their uniform distribution and stability. This can not only improve color vividness and coverage, but also enhance the application performance of the coating.
Plastic and rubber
In plastic and rubber processing, dispersants are used to promote the uniform distribution of fillers (such as carbon black, silica, etc.) in the polymer matrix, thereby improving the physical properties and surface quality of the materials.
Cosmetics
The application of dispersants in cosmetics includes dispersing pigments and active ingredients to enhance the texture, luster, and usability of products. For example, dispersants are often used in liquid foundation and sunscreen to ensure uniform color and smooth application.
Pesticides and fertilizers
Agricultural dispersants are used to disperse and stabilize active ingredients, allowing them to be evenly distributed in water or other carriers, improving their effectiveness and coverage.
Ceramics and pigments
In the ceramic industry, dispersants are used to disperse ceramic powders, reduce slurry viscosity, and improve formability. In the pigment industry, dispersants can enhance the stability and color expression of pigments.
Precautions for using dispersants
Choose the appropriate dispersant
Different systems require the selection of different types of dispersants, such as anionic, nonionic, or amphoteric dispersants, to ensure good compatibility with the substrate.
Add quantity control
The amount of dispersant added needs to be precisely controlled according to actual needs. Excess may cause side effects, such as foam problems or product performance degradation; However, insufficient dispersion cannot achieve the desired effect.
Dispersion process
The effectiveness of dispersants is closely related to the dispersion process. Appropriate shear force and dispersion time can help dispersants better function and achieve optimal dispersion performance.
Storage and stability
The system with added dispersants may be affected by external factors such as temperature and light during storage, so storage stability testing should be conducted to ensure its long-term performance.
