Suggestions for the use of anti-floating color additives: the secret of guarding color purity
In the pursuit of high-quality coatings, inks and other products, the purity and durability of the color is always the focus
of attention for both manufacturers and consumers. The correct use of anti-floating additives, as a key additive to ensure
color stability, is crucial to improving product quality. In this article, we will discuss the use of anti-floating color additives
to help you better master this color guardian tool.
First, understand the basic principle of anti-floating color additives
The core role of anti-floating color additives is to improve the dispersion and stability of pigments in the system, to prevent
pigments from migrating and aggregating during drying or curing, so as to avoid the phenomenon of floating color.
Different anti-floating additives may achieve this goal through mechanisms such as wetting, dispersion, charge regulation or
spatial site resistance. Therefore, before selecting and using, it is fundamental to understand the basic principle and
mechanism of action.
Second, according to the product demand to choose the right additives
Match the type of coating / ink:
different types of coatings (such as water-based, solvent-based, powder coatings) and inks (such as UV inks, solvent-based inks)
on the anti-floating color additives have different needs. The compatibility of the additives with the base material should be
considered to ensure that they can be effectively integrated into the system without affecting other properties.
Considering pigment characteristics:
pigment type, particle size, surface properties, etc. will affect the anti-floating effect. For pigments that are easy to float, choose
additives with stronger dispersing ability and stabilizing effect.
Focus on environmental protection and safety: With the increasingly stringent environmental regulations, it has become a trend to
choose low VOC, non-toxic or low-toxic anti-floating color additives. At the same time, to ensure that the use of additives in line
with relevant safety standards to protect the health of production staff and consumers.
Third, optimize the amount and timing of addition
Precise control of the amount of addition: the amount of anti-floating color additives is not the more the better. Excessive additives
may lead to changes in system viscosity, gloss reduction or affect other properties. It is recommended to determine the optimal
amount of additives through small pilot experiments, and then gradually scaled up to pilot and production scale.
Grasp the timing of addition: In the production process of coatings or inks, the timing of adding anti-floating color additives is also
crucial. It is generally recommended to add in the pigment dispersion stage, so that the additives can fully act on the pigment particles
to form a stable dispersion system.
Fourth, strengthen the mixing and dispersing process
High-efficiency mixing equipment: using efficient mixing and dispersing equipment, such as high-speed disperser, sand mill, etc.,
can ensure that the anti-floating color additives are fully mixed with the pigment and base material to improve the dispersion effect.
Control mixing conditions: mixing speed, time, temperature and other conditions will affect the anti-floating color effect. According to
the additives and system characteristics, optimize the mixing conditions to achieve the best dispersion effect.
Fifth, Performance test and evaluation
Color stability test: After adding anti-floating color additives, the paint or ink should be tested for color stability, including weather
resistance, chemical resistance, friction resistance, etc., to ensure that the color remains stable in the long-term use of the process.
Comparison experiment: By comparing the samples with and without anti-floating color additives, the effect of the additives can be
evaluated visually. At the same time, it can be compared with other similar products to verify the superiority of the selected additives.
Sixth, continuous monitoring and adjustment
Production process monitoring: In the production process, the color stability of the coating or ink should be continuously monitored,
and problems should be found and solved in time.
Adjustment according to feedback: according to market feedback and customer complaints, timely adjustment of the type of anti-floating
color additives, additive amount or use of technology to meet changing market demand.
Conclusion
Though small, anti-floating color additives can play a big role in the world of color. Through reasonable selection, accurate use and
continuous optimization, we can give full play to their advantages, for coatings, inks and other products to bring more pure, long-lasting
color effect. We hope that the suggestions in this article can provide useful reference for your production practice, and jointly guard the
purity and beauty of color.
