Performance of polyester viscosity-reducing dispersant
Polyester viscosity-reducing dispersant is a highly efficient chemical additive that is widely used in various
industrial fields to improve the dispersion performance of materials and reduce viscosity. The following is
a detailed analysis of the performance of polyester viscosity-reducing dispersant:
1. Dispersion performance
Polyester viscosity-reducing dispersant can effectively disperse polyester particles and other polymer particles
to prevent them from agglomerating or agglomerating, so that the material remains evenly distributed in the
medium. This dispersion effect is achieved by the interaction between the polar groups on the polyester molecular
chain and the polar groups on the surface of the dispersed material, thereby forming a stable dispersion system.
In the application of polyester viscosity-reducing dispersants in coatings, inks, dyes and other fields, it can
significantly improve the dispersion performance of pigments and fillers, making the coating more uniform and smooth.
2. Viscosity-reducing performance
Polyester viscosity-reducing dispersants can significantly reduce the viscosity of the dispersion system, improve the
rheology of the dispersion system, make the product easier to operate and handle, and save energy. This performance
is particularly important in products that require good fluidity, such as coatings and inks. By reducing viscosity, polyester
viscosity-reducing dispersants can improve the construction performance and final effect of the product.
3. Stability Performance
Polyester viscosity-reducing dispersants can improve the stability of materials by reducing static electricity and surface
energy on the surface of materials, preventing them from deteriorating due to external factors (such as temperature,
humidity, etc.). At the same time, the molecular chain of polyester can also prevent the agglomeration and sedimentation
of dispersed materials to a certain extent, further improving the stability of the dispersion system. This stability performance
helps to extend the storage period of the product, reduce storage loss, and reduce redispersion costs.
4. Other performance
In addition to the above performance, polyester viscosity-reducing dispersants also have the following advantages:
Good compatibility: It can be compatible with a variety of resin systems, such as polyurethane, polyacrylate, etc.
Improve product quality: In the processing of materials such as plastics and rubber, polyester viscosity-reducing dispersants
can improve processing performance and improve the final quality of products.
Wide range of application: Applicable to a variety of industrial fields, such as coatings, inks, dyes, plastics, rubber, etc.
However, polyester viscosity-reducing dispersants also have some disadvantages, such as relatively high cost and possible poor
dispersion effect on certain specific dispersed materials. Therefore, when choosing whether to use polyester viscosity-reducing
dispersants, a comprehensive evaluation is required based on specific application scenarios and needs.
In summary
Polyester viscosity-reducing dispersants play an important role in various industrial fields with their excellent dispersing
performance, viscosity-reducing performance, stability performance and other properties. With the continuous advancement of
science and technology and in-depth research on polyester viscosity-reducing dispersants, it is believed that their application in more
fields will be more extensive and in-depth in the future.
