Application sharing of clariant high-performance color and anti-floating color water-based dispersants and new non-silicone defoamers
Recently,Clariant Industrial Applications TeamI visited the Huabaidao live broadcast room and shared details with everyone.Clariant's High-Performance Color Development, Anti-Floating Water-Based Dispersant, and New Non-Silicone DefoamerApplications.
The editor's selected Q&A is as follows:
If the VOC content of the antifreeze is too high, what should be done?
Traditional glycol-based antifreeze agents have high VOC and affect film performance.Clariant has innovatively adopted the "steric hindrance protected latex particles" technology to develop a series of emulsion paint freeze-thaw resistance solutions.Representative products include:
Dispersogen™ LFH: Anionic type, excellent color development, can also serve as a pigment dispersant.
Dispersogen™ LFT: Low odor and low foam, good low-temperature flow, suitable for sensitive formulations.
Emulsogen™ TS 200: Non-ionic, versatile and effective for emulsions such as acrylate and vinyl acetate.
Three productsNo VOC contribution.Traditional American solvent system with freeze-thaw cycle stability.
Do these anti-freeze-thaw additives affect the drying speed of the paint film?
Anti-freezing agents have a certain impact on the drying speed of the paint film, butWithin the recommended dosage rangeThis impact can be well controlled.
What is the difference in the principles of dispersion and anti-floating color?
Dispersion occurs when an external shear force is applied, where anchoring groups on the structure of dispersants and other auxiliaries act on the surface of the target being dispersed. The solubilized chains on the dispersant backbone dissolve in the dispersion medium, and the spatial steric hindrance or electrostatic repulsion of ionic groups inherent in the dispersant's overall structure prevents the redispersion and flocculation of the dispersed substances.
The stage of preventing floating color is after dispersion is completed.，The issue of floating color often refers to the color instability caused by the floating, sinking, layering, agglomeration, or flocculation of dispersed substances in a dispersed system during storage, transportation, or application.
Dispersion emphasizes the process of dispersing solids (dispersed phase) into a dispersion medium, focusing on the early production and later application processes.
Emphasizing the subsequent stability of the dispersion system to prevent color floating.，Especially in terms of color stability, it leans towards the later stages of storage and application processes. Some anti-float agents cannot serve as the main dispersants, while some main dispersants do not effectively address anti-float issues.
Is the effect of adding Genapol ED™ 3060 before and after the same?
Clariant Genapol ED™ 3060 is a multifunctional block polymer capable ofImproving the color difference issue caused by pigment flocculation during the coating drying process.By forming bridges between organic pigments and latex particles through the mechanism of "controlled flocculation," achieve Reduce surface tension, enhance wettability and compatibility; increase color strength, and reduce finger touch color difference.
During use,Adding effects earlier yields better results.Adding through grinding and dispersion can achieve effects with lower addition levels. Post-addition requires an appropriate increase in the addition amount.
It also complies with multiple environmental certifications such as the EU Ecolabel and the German Blue Angel, and is suitable for both water-based acrylic latex paint and solvent-based alkyd paint.
Is Dispersogen™ 2779 suitable for other pigments? Is it only suitable for carbon black, or can it be used in organic red and organic yellow pastes as well?
Dispersogen™ 2779 by Clariant is a dispersant specifically designed for water-based organic and carbon black pigment dispersions. APEO-freeCombining efficiency and environmental friendliness.
100% active content, high dispersion efficiency for medium color carbon black, capable of preparing 40% high-concentration stable color paste.
Color performance is superior to commercially available competitors, thermal storage stability is excellent, and an 8% additive amount is the optimal ratio.
No VOC, no hazard label, in line with environmental trends.
In addition to regular pigment carbon black,It is also an efficient dispersant for other organic pigments.It can be used in organic yellow paste.
Can Dispersogen™ PL 30 be used with other organic pigments?
Suitable forHigh-efficiency dispersion of various organic pigmentsIt is particularly suitable for dispersing medium to high pigment carbon black, enhancing the coloring rate.
If there is too much foam in the paint, which solution can be used?
Clariant W 560 is a high-performance defoamer for coatings, designed to address foam defect issues during coating application. It offers three major advantages:
Fast defoaming speed and strong durability, outperforming commercial products in shake foam and bubble tests.
Outstanding low-temperature stability, maintaining fluidity at -5℃, suitable for winter construction.
After heat storage, the performance remains stable, effectively reducing coating defects such as pinholes and shrinkage cavities.
