PLM for coatings manufacturers

What is different about coatings

In coatings, the formula drives everything that comes after it. Colour and application performance data sit beside the recipe. The VOC content and hazard classification are calculated from the raw material data inside that recipe. So the product record has to hold each raw material's properties and classification. It also has to hold the inputs your safety data sheets need. A food company can sometimes treat a specification as a document that gets approved once. You can't, because when a resin supplier changes a solvent in its grade, the label changes on every product that uses that resin.

The sector is also fragmented. CEPE, the European paint and printing ink association, represents about 800 member companies with a combined turnover of €17 billion, and most of them are small and medium firms. Few of them have an IT team that can build regulatory logic from scratch. Check whether a platform recalculates downstream outputs on its own when a raw material changes, or waits for someone to rerun them.

Formulation

Coatings formulation management means you control each recipe as a structured, versioned record. Free-text recipes in a spreadsheet don't qualify. A typical paint formula has intermediates, such as a mill base that goes into several finished products. It also carries properties computed by volume as well as weight, because coatings are sold and regulated by the litre. When a platform models only flat, weight-based recipes, every density and solids calculation ends up back in Excel.

Most coatings firms start with years of formulas spread across lab notebooks and old systems. Projects slip during data migration when a formula with a misspelled raw material code moves into the new system and quietly breaks every calculation built on it. Ask any platform vendor to show a multi-level formula with an intermediate, and ask how it reports solids by volume.

Colour

Colour turns one base formula into a family of variants, and the PLM should manage that family as one. Decorative paint makers tint a few bases with colourant sets at the point of sale. Industrial suppliers match customer shades to standards such as RAL or NCS, with a colour-difference tolerance agreed for each one. Each shade changes the pigment load, so it can change the VOC content and the hazard classification too. Colourants carry their own solvents and classified substances.

Check that the platform links each shade to its base and colourant set. Also check that it calculates the regulatory data for a tinted variant without creating a full product record for every colour.

Application performance

Application performance data are the test results that prove a coating does what its technical data sheet claims, such as drying time or adhesion to a given substrate. The PLM's job is to tie each result to the exact formula version that was tested. When a raw material changes later, you can then see which claims need retesting before the next batch ships. Industrial coatings add customer approvals, where an automotive or coil customer has qualified one specific formula version. Look for test results stored as structured fields that the platform uses to generate technical data sheets.

VOC classification

VOC classification is managed by calculating the grams of volatile organic compounds per litre of ready-to-use product from the raw materials' volatile content. The platform then checks that figure against the limit for the product's subcategory and prints both on the label. Under Directive 2004/42/EC, the Phase II limits for paints and varnishes run from 30 g/l to 750 g/l. Interior matt wall paint is capped at 30 g/l, and interior glossy wall paint at 100 g/l.

Accurate ready-to-use calculations for a 2-component system require the hardener and any thinner at the stated mixing ratio. Vehicle refinish products follow their own calculation rules. Ecolabel claims are tighter again: the 2014 EU Ecolabel criteria set 10 g/l for matt interior wall paint. Check that the platform stores the subcategory on each product and calculates at the mixing ratio. Calculated values also need to match the measured ones from ISO 11890-2 testing.

Hazard classification

Hazard classification for a coating is a mixture classification under the Classification, Labelling and Packaging (CLP) Regulation. The platform takes each ingredient's classification and concentration and applies the CLP calculation rules. These rules determine the product's hazard statements and pictograms. They also determine its signal word. Those outputs then feed the safety data sheet. The method only works if the substance data underneath stays current.

The EU classified some powder forms of titanium dioxide as a suspected carcinogen by inhalation in 2020. Then the EU Court of Justice upheld the annulment on 1 August 2025. If your classification data sits copied inside each formula, a change like that means editing every white product by hand. A central substance database means one update. Ask where classification data lives and how a change reaches finished labels.

What regulations apply

European coatings makers work under three main sets of rules, and the PLM has to produce evidence for each one.

Which PLM fits coatings

The PLM that fits coatings is a process PLM, meaning a system that calculates regulatory outputs from the formula. A discrete PLM built around CAD files and engineering bills of materials doesn't fit. Coatings manufacturers choose among four types of system. Public pricing for any of them is rare, so expect quotes based on users and modules.

Large coatings groups use process suites: AkzoNobel, for one, runs its formulations through Infor Optiva. The honest verdict is that a process suite fits most mid-sized and large manufacturers. A smaller firm with one site gets further, faster, with a formulation tool and a good SDS system. Whichever you pick, start from what it does out of the box. Every custom change you add now has to be retested at each upgrade.

Paint formulation software

Paint formulation software suits a coatings manufacturer when the lab needs to design and adjust formulas with cost data, and the regulatory outputs can come from somewhere else. Once those formulas have to drive labels and safety data sheets across several sites, the formulation module of a process PLM is the better fit. One record then serves the lab and the regulatory team.

Your number of sites matters, and so does your tinting system. A company with 200 products and one plant lives comfortably with a standalone tool. A company with thousands of tinted variants doesn't. If you buy a lab tool now, check that it exports structured formula and raw material data for later import into a PLM. If it can't, you'll pay for a second migration.

Working with coatings manufacturers

C+P Consulting runs coatings programmes in six stages. Assess and Design come first, followed by Build and Migrate. Adopt and Optimise complete the programme. The table shows which stage handles each problem described above.

Problems caught in the blueprint cost far less than problems found during UAT, so the hard coatings questions get settled early. And the people who design the process also build it, which means the platform runs the design you signed off. One example comes from an ingredients manufacturer with a broad, fast-moving portfolio that still did its regulatory and labelling calculations by hand. C+P automated those calculations from structured specification data, and the compliance cycle got faster across the portfolio. Structured raw material data likewise allows the label to be calculated for coatings.

How to get started in coatings

Your first decision is whether your raw material data is clean enough to calculate from. Pull 20 formulas and check each raw material for a current supplier safety data sheet and a classification. Check its volatile content figure too. The gaps you find will tell you how big the migration is and which option in the comparison above you can realistically run. They also show what adoption will take, and adoption is the measure that counts, because a go-live date proves nothing. C+P Consulting helps manufacturers choose and implement plm for paint and coatings. It also supports adoption, and its work extends to ink and specialty chemicals. Talk to us about your programme.
