Specify by Substrate, Exposure, and Finish
The most common sourcing mistake is asking for "paint" or "coating" without the substrate and finish.
An industrial protective coating, a decorative wall emulsion, and a printing ink are formulated for very different demands, so a quote given without context is hard to compare.
A stronger enquiry names the substrate (metal, wall, wood, packaging), the exposure (interior, exterior, chemical), and the finish required.
That improves quote quality and prevents specifying a decorative product where a protective one is needed.
- State the substrate and exposure conditions
- Specify the finish (matt, gloss, texture) where relevant
- Give the area or quantity for coverage-based pricing
Finished Product or Raw Material?
Buyers in this category split into two groups: those sourcing finished paints and inks, and coating/ink manufacturers sourcing raw materials — resins, pigments, thinners, and additives — for their own production.
These are quoted very differently, so state which you need.
For raw materials, specify the resin type or additive function and any performance target so suppliers quote the correct item.
- Specify finished product vs raw material (resin, pigment, additive)
- For resins, state the type (epoxy, alkyd, acrylic) and grade
- For additives, state the function and dosage target
TDS, VOC, and Compliance
For paints, coatings, and inks, confirm the Technical Data Sheet (TDS), coverage or application data, and safety documentation.
Where VOC limits or specific performance requirements apply, confirm them before commercial closure.
Ask for recent lot-level documentation, and for packaging inks or regulated coatings, confirm any compliance requirement up front.
- TDS matched to the application
- Coverage or dosage for accurate quantity and pricing
- Safety documentation (MSDS) and VOC data where relevant
- Compliance requirements for packaging or regulated coatings
