Characteristics of Methyl Beta Cyclodextrin and Its Application in Coating Thickener

Methyl beta cyclodextrin (M-β-CD) is the most effective cosolvent for insoluble substances and the best stabilizer for many chemicals. Because M-β-CD has excellent solubilization and inclusion, and because it is soluble in water and organic solvents, it is widely used in medicine, food, pesticide, cosmetics, daily chemicals, chemical industry, textile dyeing and finishing, chromatographic analysis and functional materials.

Because the thickener can improve the fluidity, construction, thixotropy of the coating, and overcome the disadvantages of falling and settling. Therefore, thickeners are widely used in water-based coatings, adhesives, textile printing and dyeing paste, ink, synthetic emulsion or natural emulsion thickening.

The viscosity of thickener system can be adjusted efficiently by complexing and removing hydrophobic groups of hydrophobic modified thickener, in order to improve the pumpability and filling ability of thickener, simplify the production process and reduce the cost. Especially when the polyurethane thickener with methyl betamethasone is used to thicken the coating, the thickening efficiency can be improved, and the coating is more environmentally friendly and the performance is better.


β-CD the viscosity control of low solid content thickener is effective, but the regulation of high solid content thickener viscosity is limited. Methyl beta cyclodextrin is a very efficient viscosity inhibitor. Polyurethane thickener only needs 7% methyl betamethasone cyclodextrin to reduce the viscosity of the system to 2000 mPa·s, to meet the requirements of use. Its efficiency is higher than 10% ethylene glycol.

Some studies have pointed out that methyl beta cyclodextrin can maintain the stability of coloring dispersion and can act without adding other components and dispersions. It can also improve the compatibility of incompatible surfactants and overcome adverse water sensitivity and foaming property. And in improving colorant compatibility, there is no need to add surfactants.


The advantages of using methyl betamethasone in thickeners are:

Save organic solvent, meet the requirements of environmental protection.

It can improve the thickening efficiency.

Increase the compatibility of thickener in coating system and reduce binding time.

Improve the compatibility of colorants in coatings.

Improve water resistance and reduce foam.


In addition to the above advantages, it has no adverse effects on the fluidity, flow hanging, flattening, gloss, coloring stability and thermal aging stability of the coating. Therefore, the application of methyl betamethasone in thickener is a good product worthy of promotion.
