What is Polyurethane Thickeners ?
PU Thickener, also named as HEUR (Hydrophobically Modified Polyurethane Rheology Modifier), it is a kind of nonionic, hydrophobically modified polyurethane rheology modifier, it commonly used in water-based coatings, various inks, adhesives, and construction chemicals to adjust viscosity and rheological properties to improve substrates performance.
- Associative thickening mechanism.
- Excellent rheology control.
- Outstanding leveling performance.
- Good anti-spatter properties.
- Highly formulation-sensitive.

Improving Your Paints & Coatings with Celotech Ruico Polyurethane(PU) Thickeners
Considering Celotech Ruico as your Polyurethane(PU) Thickener supplier will be a wise decision. Since We are a leading original factory of Polyurethane(PU) Thickener with 13 years R&D, manufacturing experience in China.We provides low/middle/high shear rate PU thickener, which improve splashing, non thickening pure leveling, excellent flow leveling performance. Our technical team can custom polyurethane(PU) thickener formulation for you too.
Types of Celotech Ruico Polyurethane Thickeners Models
Our Polyurethane(PU) thickener provides different KU viscosity and improves the fullness of the emulsion by lowering Pseudoplasticity, suspending anti-delamination by different models:
Provides low pseudoplasticity, suspended anti delamination.
Slightly thickened emulsions by excellent flow leveling.
TI 3.8 for excellent thickening efficiency and strong resistance to solvent dilution in industrial coatings
High solid content and efficient polyurethane thickener, thickening varnish without delamination.
With excellent thickening and solvent dilution resistance in industrial paints.
Has excellent leveling performance, providing KU viscosity.
Advantages of Polyurethane Thickeners
Mainly features and advantages of Celotech Ruico polyurethane(PU) thickeners, which are functional to your project and applications:
It can effectively control viscosity in low/medium/high shear for your paints. Suitable for various application methods including spraying, roller coating, and brushing ,improving your paints flow feel.
Adding PU thickener makes less prone to brush marks and roller marks in your constructions. Improves film smoothness and appearance.
PU thickeners have even no negative effect on gloss, so they are ideal for mid- to high-gloss formulations, because they have high transparency and non-particulate nature.
PU thickeners will not reduce water resistance or scrub resistance of the final coating.
Compared to HPMC, it does not have the viscosity reduction caused by enzymatic degradation, resulting in a longer shelf life.
PU thickeners are compatible with a wide range of polymer emulsions, pigments, and additives, and perform well over a broad pH range.
Polyurethane Thickener Usage
PU Thickener can partner with your HEC to optimize the application and appearance by controlling the medium-high shear viscosity precisely, Enhancing film leveling, reducing roller and brush marks, suitable for matte to high-gloss systems depends on minimal gloss affects.
Compared to Cellulose ether thickeners, PU Thickener has less impact on the durability of exterior walls. Since its excellent shear-thinning properties, stable leveling flow properties, and doesn’t reduce the coating’s water and alkali resistance significantly.
PU Thickener is widely used in packaging adhesives, paper adhesives, laminating water-based adhesives, by providing you stable thixotropy, controlling coating thickness, and few affects bond strength.
PU Thickener is a critical additive in making water-based screen printing inks, Â Flexographic inks, gravure inks, Improve your ink stability during printing, it also can control low-shear and high-shear viscosity precisely.
Polyurethane Thickeners Dosages and Handling
- PU Thickenerdissolves slow than other thickeners. It is recommended to prepare a concentrated solution at 25-50%, and dissolve it in 60-70°C water.
- The stock solution is perfectly miscible in cold water.
The usage volume should depend on the final desired viscosity range. - The recommended percentage is between 0.5% and 5%. It is advisable to arrange it with a small volume according to the prescription.
Polyurethane Thickeners Safety, Packaging and Storage
- Celotechcuiro Polyurethane(PU) thickener packaged in 50kg and 200kg IBC plastic drums, the container remains sealed originally.
- With a storage period of 12 months at 5-35℃and must be protected from light and heat.
- It is insensitive to UV rays, will not turn yellowunder the sunlight.
