Technical Guides For Coating And Ink Formulators
Ten guides built from the published technical data on this site. Every number quoted in them comes from a manufacturer data sheet, and where the source publishes nothing, the guide says so rather than estimating.
QK Additive Cross-Reference List
Sixty-nine QK additive grades and the commercial grades they are positioned against, as published by the manufacturer.

How To Choose A Wetting And Dispersing Agent
Eight dispersants, four decisions. Binder system first, then active content, then pigment class, then the grinding procedure.

Dispersant Dosage By Pigment Type
Published dosage bands for eight QK dispersants, side by side, with the arithmetic that makes them comparable.

Rheology 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.

Preventing Sagging In High Build Coatings
Sagging is a viscosity recovery problem. Three sag control resins and two rheology additives attack it from different directions.

Aluminium 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.

Surface Tension And Coating Defects
Craters, pinholes and fisheyes are wetting failures. On a fast line it is dynamic surface tension, not static, that decides whether they appear.

Waterborne Conversion Additive Checklist
The additive package fails before the binder does. Six checks to run before the first waterborne trial batch.

Non-Ionic Surfactant Selection By HLB And Cloud Point
Seventeen published grades across three families, from HLB 7.6 to 18, and the two numbers that narrow them down.
Read the guide
Molecular Sieve Grades And How To Select One
Over 110 adsorbent products, and a selection method that starts from the separation duty rather than the type number.
