Matt powder viscosity reducing dispersant: lighting up the light of multi-field application
Mat powder viscosity reducing dispersant is widely used in industrial fields such as coatings, inks, plastics, rubber,
etc. Its core function is to reduce the viscosity of matt powder (such as silica, matting powder, etc.) in the system,
while improving dispersibility and preventing agglomeration, thereby optimizing product performance. The following
are its specific applications and advantages:
1. Coating industry
Wood paint and furniture paint
Function: reduce viscosity, improve grinding efficiency, prevent matt powder sedimentation, improve powder
arrangement, and improve leveling and brightness.
Case: After adding a specific dispersant to a certain brand of wood paint, the viscosity is reduced by 30%, the grinding
time is shortened by 20%, and the storage stability is significantly improved. 、
UV matte paint
Function: reduce viscosity while maintaining gloss and improve storage stability.
Case: Anjikang 6820 dispersant in UV matte paint, the semi-matte system has better thermal storage stability than
competing products, and the full matte system has no stratification and agglomeration.
2. Ink industry
Function: improve the dispersibility of matt powder in ink, prevent floating color and improve printing effect.
Case: After adding dispersant to a water-based ink, the matte powder particle size distribution is uniform, and the
printing clarity is improved by 15%.
3. Plastic and rubber industry
Plastic
Function: Reduce the viscosity of matte powder in plastic, increase the filling amount, and improve mechanical properties.
Case: After adding dispersant to a PP plastic, the matte powder filling amount is increased from 20% to 30%, and the
tensile strength is increased by 10%.
Rubber
Function: Promote the uniform dispersion of matte powder in rubber, improve wear resistance and anti-aging properties.
Case: After adding dispersant to a tire rubber, the wear resistance is improved by 20% and the service life is extended by 15%.
4. Key performance advantages
Significant viscosity reduction effect
Most dispersants can reduce the viscosity of the system by 20%-50%, such as FC-7610, which has an outstanding viscosity
reduction effect in UV matte powder system.
Improve dispersibility and stability
Prevent secondary flocculation of matte powder through steric effect, such as Coadd™ D-73, which performs well in inorganic
pigments and fillers and has excellent storage stability.
Does not affect transparency and gloss
Excellent dispersants can maintain system transparency, such as Anjeka 6871, which does not affect gloss while reducing viscosity.
Strong versatility
Applicable to a variety of systems such as water-based, solvent-based, UV, etc., such as BESM®9246, which performs well in both
solvent-based and solvent-free coatings.
5. Application Notes
Dispersant selection
Select a suitable dispersant according to the type of matt powder, substrate type and process conditions. For example, a dispersant
with a high anchoring group density is required for small-particle matt powder.
Addition amount optimization
The initial addition amount is recommended to be 10%-50% of the matt powder mass, and adjusted according to the viscosity test
results to avoid excessive color floating.
Process control
Dispersion temperature, speed and time need to be strictly controlled. For example, the water-based system recommends a speed
of 500-1500rpm and a dispersion time of 20-60 minutes.
Matt powder viscosity-reducing dispersants significantly improve the application effect of matt powder in various industries by
reducing viscosity, improving dispersibility and stability. Selecting a suitable dispersant and optimizing process parameters are the
key to achieving high-performance products.
