rheological agent for PU sealant

The rheological agent for PU sealant provides superior thixotropy, maintaining viscosity at rest but allowing smooth flow during dispensing. It prevents sagging in vertical joints and promotes uniform curing. This agent stabilizes filler dispersion, improves dimensional retention, and eliminates bubble formation. It is compatible with a wide range of polyurethane sealant formulations, providing steady flow control and enhanced visual quality after curing.
