TDS-Thickening Agent 5302B

TDS-Thickening Agent 5302B

5302B is composed of nonionic water-based polyurethane. It is a polyether polyurethane associative thickener, medium associativ and shows medium to high viscosity in the low shear rate range, pseudoplasticity. It has excellent leveling properties. It provides medium shear viscosity. It is used in color mixing systems. Its excellent dispersion properties can help wet and disperse the pigments in the formula, making the paint film uniform and build well without affecting the gloss.

APPLICATIONS

 

5302B is used in water-based synthetic leather, water-based coatings, water-based adhesives and other fields. It is used in combination with cellulose ethers and polyacrylic acid thickeners to give the coating better leveling, splash resistance and other properties. It can resist microbial degradation. Its thickening ability depends on the emulsion structure, particle size and emulsifier as well as the film-forming additives and surfactants in the coating.

 

APPLICATION PROCESS

 

5302B can be added during the grinding or paint mixing stage, or after adding the emulsion. It is recommended to add 0.5-3% (of the total formula). The exact amount should be determined by different formulas and required viscosity. In order to better disperse and avoid agglomeration, dilute it with water or co-solvent at a ratio of 1:1 before adding it.

 

Precautions

1

Associative thickening is affected by temperature. Low-temperature viscosity is higher and high-temperature viscosity is lower. Temperature conditions should be considered when designing the formula;

2

When the batch of raw materials to be thickened is changed, another test should be conducted to determine the amount of thickener;

3

Its own viscosity has a temperature effect, so it is easy to pump above 20℃.

PACKAGE

50KG /120KG plastic pail.

SHELF LIFE

5302B is recommended to store at 5-35℃ in original sealed packing. Shelf life is 12 months from the date of manufacture.
