DISPARLON _AQ-870(Rheology control agent for waterborne systems)
DISPARLON AQ-870 is a rheology control agent composed of a polyamide. DISPARLON AQ-870 forms a network
structure by interacting with paint components in a coating system, prevents settling and hard caking, andimproves pigment orientation. Unlike general waterborne thickeners, DISPARLON AQ-870 can provide highthixotropic property without excess viscosity increasing.

■ADVANTAGES● Excellent anti-settling property● Imparts high thixotropic property without excess viscosity increasing● Easy incorporation■APPLICATIONSDISPARLON AQ-870 can be used in a wide range of waterborne coating systems.

■INCORPORATION
Additive levels
Method::1.0~6.0% by wt. on total formulation.

Can be added at each production stage. Post-addition at a final production stage with adissolver is recommended.

Keep temperature from a room temperature up to 40°C during dispersing.

9.1■STORAGE● Keep from freezing. Freezing causes degradation of quality and performance.

● At low temperature (below 10°C), this product loses the fluidity and becomes paste form. In this case, heat at
50°C or more and fluidize again before use.
