Product Overview
CHLUMICRYL® TH-255D is a polyurethane-based leveling and rheology modifier for waterborne resin and emulsion systems. The grade focuses on high-shear thickening with a leveling contribution, and its application range includes textile finishing, industrial and architectural coatings, inks and adhesives. It can be evaluated where uniform film build, hiding and reduced roller spatter are important. The listed 20% and 40% solids options must be treated as alternative supply specifications rather than a broad tolerance. Confirm the selected option and test the full formulation's shear response, leveling, storage stability and finished-film properties before changing an existing additive package.
Grade Characteristics
- High-shear rheology control
- Leveling contribution
- Supports uniform film build and hiding
- Can reduce roller spatter in compatible systems

These values are technical selection data, not a batch-specific certificate of analysis. Test methods, current specifications and any acceptance limits should be confirmed before ordering.
应用
- Textile finishing and fabric coatings
- Waterborne resin and emulsion systems
- Waterborne industrial and architectural coatings
- Waterborne inks and adhesives
- Petrochemical water-treatment formulations following compatibility testing
Formulation and Handling
The documented starting range is 0.5-2.0% of the total formulation; confirm the dosing basis and supplied solids option.
Verify addition sequence, compatibility and the final leveling response through formulation trials.
Review the current SDS before handling.
- The listed solids options require confirmation of the actual supply specification and availability.
- Unchanged gloss, unlimited pH compatibility and universal replacement equivalence are not specified.
Check binder compatibility, substrate preparation, application conditions and final coating or bond performance in your own formulation. Waterborne use does not by itself establish solvent-free status or a hazard classification. Consult the current safety data sheet and use appropriate industrial handling controls.
