Hydrophobic association alkali swelling thickening agentT-940
Introduction：
T - 940 for alkali soluble acrylic emulsion thickener, its structure viscosity performance similar to that of high molecular weight cellulose thickener (HEC). This product showed a higher resistance than cellulose thickener roller paint splash, but also showed greater pseudoplastic rheological properties. T - 940 effective improving its low shear viscosity, so that the latex paint has a larger flow resistance to hang. When dilute, viscosity loss is small.
T - 940 can be used to from flat to the external walls of a light emulsioni paint. It is usually in low dosage, the effect was synergistic thickening agent, can strengthen the tank structure in order to avoid such settlement or sag. With T - 940 family, thickener preparation of coating has high yield value and gel structure, this structure will be shown after the shear force disappears, so T - 940 is suitable for the preparation has moderate stereoscopic pattern effect of the coating.
Product characteristics:
Have efficient thickening effect and higher pseudoplasticity.
Excellent resistance to splash, paint roller mobile performance is good, better scrub resistance and water resistance.
A good coating stability, settlement, not tank look thick and creamy.
Good environmental quality.
The biological stability of reliable.

Instructions：
The usage of this product according to customers' formula design, suggest to add 0.2% ~ 1.0% of the total amount for the formula. When used according to the proportion of 1:1 diluted at least, slowly add thickening system, and make sure that the thickening system in pH 8.5 9.0.
Customers can also according to the production, storage, construction and film forming of the different requirements of adjusting dosage, can be used alone, can also be used with other kinds of thickener, to meet the requirements of the rheological properties of formula design.
