Coating Additives
The QK additive range covers dispersion, wetting, defoaming, levelling and rheology control for waterborne, solventborne, UV and plastisol systems.
Every Coating Additives Grade We Publish
Fourteen QK grades are published in full on this site, and the complete cross-reference list runs to sixty-nine. Each grade is described the way a formulator needs to read it: what the chemistry is, what the typical data are, how much to add per pigment class, where in the process it goes, and which commercial grade it is positioned against.
QK4200 Liquid Rheological Agent
Liquid polyurea rheology additive for waterborne and water/glycol-ether systems, dosed for anti-settling or anti-sag.

QK4100 Liquid Rheological Agent
Liquid polyurea thixotrope for solventborne and solvent-free coatings, PVC plastisol and air-drying resin systems.

- A commercial grade has gone on allocation and the formulation needs an alternative that behaves the same way
- Grind cycles are long and mill base viscosity is capping pigment loading
- Settling, sagging, cratering or poor metallic orientation is failing panels
- Additive suppliers publish a marketing page and hold the technical data until after the enquiry
Who It Is For
- Paint and coating manufacturers running waterborne and solventborne lines
- Pigment concentrate and tinter producers
- Ink and overprint varnish formulators
- Toll manufacturers who need a post-addable viscosity lever
Why Buyers Choose This Range
- Dosage published as a ladder by pigment type, not as a single number
- Addition point and shear conditions stated for every grade
- Storage window, shelf life and packing on every data set
- VOC and APEO status declared where the source data declares it
Typical Application Scenarios
- Converting a solventborne industrial topcoat to water
- Rebuilding a carbon black concentrate that thickens in storage
- Lifting film build on vertical steelwork without runs
- Fixing craters on a high-speed coating line
