Compare iron oxide material cost at the additions that achieve the same accepted colour and product requirements. Price per kilogram and an isolated tinting-strength percentage cannot settle the finished-product economics.
Establish a real colour match first
The BAYFERROX 504 sheet shows that colour and strength results have a defined reference system. Do not turn a percentage from that system into a guaranteed dose-reduction factor for another formulation.
Use the actual binder, substrate or polymer and approved preparation. Retain any colour-correction ingredients and their cost. If the candidate meets strength but misses shade, it has not yet met the same target. Accept the complete requirement before entering the economic comparison.
| Hypothetical accepted batch | Pigment spend |
|---|---|
| A: 5.0 kg at USD 1.50/kg | USD 7.50 |
| B: 4.5 kg at USD 1.70/kg | USD 7.65 |
| B break-even price at that accepted addition | 7.50 / 4.5 ≈ USD 1.6667/kg |
Preserve the calculation boundary
These additions and prices are invented. B’s lower assumed dose does not offset its premium within this pigment-only example. Dispersion energy, other ingredients, rejected output and application costs are excluded and should be added if they differ. Do not claim a whole-product saving from this restricted numerator.
Send ENVO the current pigment and addition, target reference, method and commercial quantity. Request actual candidate documents and a trial sample. The qualified dose should come from the buyer’s evidence, not an unverified percentage copied from a supplier brochure.
