RT7275A Polyurethane Thickener
RT7275A is a non-ionic hydrophobically modified ethoxylated urethane (HEUR) rheology modifier that effectively improves medium and low shear viscosity while providing optimal thickening ratios, delivering superior rheology properties to water-based coatings. It significantly enhances flowability, leveling, hiding power, uniform film formation, and gloss performance.
- Antimicrobial and anti-mold properties
- High-efficiency thickening
- Outstanding splash resistance
- Excellent in-can stability
- Free from organic tin
- Environmental friendly

Use & Compatibility
Recommends a dosage of 0.2-0.5% (as a finished product) to the total coating volume, with the exact dosage to be determined through experimentation.
RT7275A can be added directly and added slowly under low-speed stirring.
The dosage of the RT7275A additive should be adjusted according to the requirements of the product.
RT7275A Typical Applications
RT7275A is specially formulated for low-solid-content applications, delivering an outstanding balance between leveling and sagging, excellent color rendering, and superior water separation performance.
RT7275AÂ rheology modifier is compatible with cellulose thickeners and alkali-swelling thickeners and can be freely combined with them.
RT7275A PU rheology modifier can effectively thicken under low solid content with good water retention and separation resistance.

FAQ About RT7275A
Yes, it is compatible with a range of cellulose ethers like HEC, HPMC, MHEC, and alkali-swelling thickeners, enabling tailored rheology control performance.
You should disperse RT7275A under low-shear conditions, then stir moderately using the tool. You had better avoid high-shear mixing to preserve the hydrophobic chain structure.
Usually, RT7275A will not affect brushing, rolling, or spraying ways, and it can enhance splash resistance during application processing.
Standard handling is OK; you should avoid long skin or eye contact. You also can wear gloves and safety glasses if it is necessary.
RT7275A maintains good viscosity and flow properties within normal temperature ranges. It may slightly increase viscosity at low temperatures; viscosity will reduce slightly at high temperatures, but overall its stability is superior compared to standard HEUR thickeners.
