Introduction
RHEOLATE®
HX 6008 is a novel nonionic synthetic associative thickener (NiSAT) which has outstanding rheological properties for aqueous applications. It develops high shear viscosity (ICI) very efficiently, and additionally displays some mid-shear viscosity contribution. RHEOLATE
® HX
6008 is effective in a broad range of latex chemistries.
Chemical and Physical Data

Incorporation and Levels of use
RHEOLATE® HX 6008 can be used as supplied or, if necessary, further diluted with water. Addition can take place at any time during the manufacturing process, but incorporation into the mill base before the letdown is recommended. RHEOLATE® HX 6008 can be combined with other associative rheological additives, clay based thickeners or cellulosic thickeners for higher packaged viscosity. It is important to assess the effectiveness of RHEOLATE® HX 6008 in the entire system, as performance can be affected by other raw material ingredients. Further detailed background information on the technology of nonionic synthetic associative thickeners can be found in the Elementis Specialties RHEOLOGY HANDBOOK.
Typical use levels of RHEOLATE® HX 6008 are in a range 0.1% to 1.5% (product weight) related to the total system weight.
Key Benefits
Extremely high efficient thickener with both ICI and KU properties.
Compatible in various resin systems and especially efficient with acrylic and sty-rene acrylic resins.
Excellent balance of sag, flow, and lev-elling.
Minimal effect on final paint properties.
EU Ecolabel confirmation available.
