Additives Your Formulation Already Knows How To Use
QK wetting agents, dispersants, rheology controls and levelling agents, each published with the commercial grade it is positioned against and the dosage range by pigment type.
Solids Viscosity Density And Dosage On Every Grade
Active content, density, pH, solvent, storage window, shelf life, packing and the dosage ladder by pigment class are on the product page, not behind a form.
One Supplier Across The Whole Additive Package
Dispersion, wetting, defoaming, levelling, rheology and sag control from a single source in Tianjin, with pigments, surfactants and molecular sieves alongside.
Five Product Families For Coating And Ink Plants
Coating and ink raw materials: wetting and dispersing agents, rheology control agents, levelling and defoaming additives, sag control resins, titanium colour pigments, non-ionic surfactants and molecular sieve adsorbents.

Paint, ink and coating manufacturers, pigment concentrate producers, textile and metal cleaning formulators, and industrial gas and adsorbent users.
Automotive Coatings
Basecoat orientation, clearcoat gloss and sag control on vertical panels, in both water and solvent.
See the additive package
Industrial And Protective Coatings
Anti-corrosive primers, marine and coil systems, where settling, sagging and colour drift decide whether a batch ships.
See the additive package
Wood And Furniture Coatings
Waterborne wood finishes where grind quality, clarity and low VOC all have to hold at once.
See the additive package
Printing Inks And Overprint Varnish
Waterborne and UV inks, inkjet and overprint varnish, where dynamic surface tension and carbon black behaviour set the limits.
See the additive package
Textile And Industrial Cleaning
Emulsifiers, levellers and low-foam cleaning surfactants selected on HLB and cloud point.
See the additive packageThe Data Should Not Arrive After The Purchase Order
You know which commercial additive grade your formulation is built around. What you need is a China-based source for the same function, with the typical data and the dosage guidance written down, so a trial can start without a month of emails.
What Usually Goes Wrong
- A commercial grade goes on allocation and there is no documented alternative
- Supplier pages publish a marketing paragraph and hold back the dosage figures
- A single recommended percentage hides the fact that dosage depends on pigment class
- The handling constraint that decides the trial is buried or missing
What We Publish Instead
- Every QK grade on this site is published with its chemistry, its typical data, its dosage range by pigment type and its addition instructions, plus the commercial grade it is positioned against. Nothing is held back until after you order.
- Dosage as a ladder across inorganic pigment, organic pigment, titanium dioxide and carbon black
- Addition point, shear level and any pH adjustment needed before the additive goes in
- Storage window, shelf life and packing on every grade
Four Problems We Get Asked About Most
Equivalent Grade Sourcing
You already know which commercial grade your formulation is built around. This is how a QK alternative gets qualified without guesswork.
Read the stage by stage guideWaterborne Coating Conversion
Moving a solventborne formulation to water breaks the additive package first. This is the order the pieces usually have to be replaced in.
Read the stage by stage guidePigment Dispersion And Colour Development
Grind time, mill base viscosity, jetness and storage stability are one problem, not four. They are all set by the dispersant.
Read the stage by stage guideSag Control And Metallic Orientation
Two problems that share one cause: what the coating does in the sixty seconds after it leaves the gun.
Read the stage by stage guideTechnical Guides Written From The Published Data
No case studies are published here, because no verified project data exists to publish. What does exist is the technical data, so that is what the guides are built from.
QK Additive Cross-Reference List
Sixty-nine QK additive grades and the commercial grades they are positioned against, as published by the manufacturer.
Read the guideHow To Choose A Wetting And Dispersing Agent
Eight dispersants, four decisions. Binder system first, then active content, then pigment class, then the grinding procedure.
Read the guideDispersant Dosage By Pigment Type
Published dosage bands for eight QK dispersants, side by side, with the arithmetic that makes them comparable.
Read the guideRheology Control In Waterborne And Solventborne Coatings
Two polyurea rheology additives, one for each continuous phase, and the dosage split between anti-settling and anti-sag.
Read the guidePreventing Sagging In High Build Coatings
Sagging is a viscosity recovery problem. Three sag control resins and two rheology additives attack it from different directions.
Read the guideAluminium Pigment Orientation In Waterborne Basecoats
Cloud patches and mottling come from flakes that did not lie flat. Two chemistries fix it in water, and both have a pH condition attached.
