product description:
This series of products is a new type of waterborne polyurethane associative thickener, which can impart a lower thixotropy and a lower yield value to the thickening system than the thickening of cellulose and acrylic, making the thickener system There is a certain viscosity recovery lag period after shear thinning, so the thickener system has good fluidity, leveling and brushing feel; urethane associative thickener is a low molecular weight oligomer Compared with other thickeners, it has the best anti-mixing splattering property; it has strong affinity with polymer emulsion polymer, which makes the coating film denser and improves the scrubbing resistance of the coating film; The commonly used emulsion film-forming polymer has good compatibility, does not affect the gloss of the coating film, and is not affected by the pH value of the system; has surface activity, and has the functions of dispersing stable resin, pigment and auxiliary agent. This series does not have adverse effects on the environment, it is a standard green polymer material.
Application range:
Used in all kinds of latex paints, waterborne wood lacquers, waterborne industrial lacquers, water-based adhesives, water-based inks, leather finishing
Agents, textile coatings and other systems.
Precautions:
1. Associative thickening is affected by temperature, low temperature viscosity is high, and high temperature viscosity is low. Temperature conditions should be considered when designing the formula;
2. When the batch of thickened raw materials is changed, it should be tested to determine the amount of thickener;
3. The product will crystallize at low temperature, and the crystallization will not affect the product performance. Once crystallization occurs, it must be heated to melt the crystal before it can be used.
