1.Medium and low shear thickener
2.Excellent thickening effect, fluidity and leveling property
3.Free of organotin, APEO and other toxic substances
4.Good dispersibility, which helps wet and disperse pigments in the formulation
5.Non-ionic nature, with performance unaffected by the pH value of the system
6.No adverse effect on the gloss of formulated products
HEUR-656A is a liquid water-based thickener based on polyurethane, featuring medium and low shear performance and easy application. It outperforms traditional cellulose-based thickeners (e.g., HEC hydroxyethyl cellulose, MC methyl cellulose, etc.) and acrylic thickeners in leveling property, film gloss and water resistance.

1.Dosage: 0.2-2.0% relative to the total formulation. Conduct tests to determine the optimal dosage according to the system components and required fluidity before addition. It can also be diluted with water-based solvents or water for better dispersibility.
2.It can be added either before or after grinding. It is recommended to add a portion in the early stage and the rest in the later stage.
3.No pre-dilution is required for use; if dilution is needed, water-based solvents can be used.
1.Associative thickening is affected by temperature: viscosity is higher at low temperatures and lower at high temperatures. Temperature conditions should be considered when designing the formulation.
2.Re-test shall be conducted when the batch of thickened raw materials is changed to confirm the dosage of the thickener.
3.This product may crystallize at low temperatures, and crystallization does not affect product performance. If crystallization occurs, heat the product to melt the crystals before use.
1.Store in the original sealed container
2.Recommended storage temperature: 6-28℃
3.Must be used up within 12 months from the date of production
4.Avoid direct sunlight and contamination by other substances
