AgeSin® RH-A4425 is a liquid 流变助剂 designed for waterborne systems. It builds a reversible rheological network through intermolecular hydrogen bonding, precisely regulating in-can 粘度, providing long-term anti-settling performance, and significantly improving anti-sagging properties. Its rheological performance is not affected by pH, and it does not compromise gloss or transparency. Suitable for a wide range of waterborne coating formulations.

Wood/Furniture 水性涂料: 清漆es, pigmented primers, matte topcoats, outdoor 木器涂料.
Architectural 水性涂料: interior wall latex paints, exterior weatherable coatings, textured finishes, putty.
Urea groups form reversible hydrogen-bonding networks with waterborne resin emulsions and pigment particles
Typical pseudoplastic rheology: high 粘度 at low shear (anti-settling), rapid 粘度 drop at high shear (smooth application), quick recovery (anti-sagging)
APEO-free, low VOC
★Special attention: Due to strong rheological efficiency, may cause sharp 粘度 increase. Pre-dilution is recommended if needed.
High 粘度 at low temperature; pre-dilution can reduce 粘度. Storage stability of diluted solutions should be tested individually.
Storage may show slight turbidity, which does not affect rheological performance.
AgeSin® RH-A4425 should be added to the coating system under moderate shear force to ensure uniform mixing and rapid dispersion. No special temperature control is required. It can be added during the grinding stage or post-added to adjust 粘度. If suitable for the system, a significant increase in rheological effect will occur, depending on time and polarity. Rheological effects can generally be evaluated 2–4 hours after mixing.
0.2%-5% additive dosage based on total formula to prevent sedimentation.
0.5%-1% additive dosage based on total formula to prevent sagging, but this depends on the overall solid content of the formula.
