Coating and paint deformulation: how do I compare laboratories?
Short answer
Compare coating deformulation laboratories by the physical forms they can receive, the questions they can investigate, the report they deliver, and their confidentiality and shipping arrangements. Describe the actual wet product, powder or cured film before choosing a scope, because those specimens preserve different parts of a formulation. Ask for conclusions tied to that specimen, supported component identities and proportions, and explicit limits rather than assuming that a service title promises an exact production recipe.
What should you ask every lab before sending a coating sample?
Begin with one decision, such as checking whether a new unused batch retains the reference coating’s binder and additive pattern, then give each laboratory the same brief. A broad request to analyze paint can otherwise produce different scopes that cannot be compared simply by counting component names in the resulting reports.
Which physical forms can you receive?
Ask separately about wet coating, powder, cured film and film attached to a substrate, because a receiving decision concerns the actual specimen rather than the coating-family name. Confirm the eligible form before preparing a substitute, since changing to a film can change the question as well as the shipping route.
Will you investigate the wet formulation or the retained film?
Define whether the target is the incoming product, retained nonvolatile material or a specified layer, because lost solvents and reacted ingredients are not an untouched record of the original mixture. An agreed target prevents a film result from being read as a complete wet-paint recipe.
At what identity level will you name components?
Ask whether the report distinguishes a specific compound, a resin or additive family, an inferred ingredient and an unresolved fraction, because these statements carry different evidential weight. A long ingredient list is not informative if its certainty levels are hidden.
What does each reported proportion represent?
Ask whether amounts refer to the supplied paint, dried solids or an extracted fraction, and whether they are estimates or supported quantitative results, because different denominators cannot be treated as interchangeable. A prepared fraction can enrich an ingredient without indicating a higher concentration in the original product.
What supporting evidence and limitations will the report include?
Ask for a description of the conclusion, component table, supporting data and unresolved portions, because the report must connect its findings to the decision rather than present unexplained signals. The intended reader also needs to know which claims the chemistry does not establish.
How will a reference and candidate be compared?
Ask whether corresponding material states, layers and preparation histories will be aligned, because a wet reference and a cured candidate introduce differences before analysis starts. Name the reference and candidate roles so the interpretation addresses the requested substitution or batch question.
How are sample information and results kept confidential?
Ask what confidentiality agreement covers the product information, analytical results and access arrangements, because a public service description alone does not define the handling of a particular project. Clarify the handling of remaining material alongside the information, rather than assuming that both follow the same retention rules.
What shipping instructions apply to this specific specimen?
Ask about declaration review, required documents, authorized shipment and the proposed packaging form, because a parcel that can travel is not automatically a specimen the laboratory has agreed to receive. These details should correspond to the material approved for the agreed analytical question.
What do several labs publicly say they offer for coating deformulation?
What does EAG Laboratories publicly list?
EAG Laboratories includes paints, architectural coatings and finishes among the coating materials listed on its deformulation page. EAG Laboratories also lists competitive product characterization and identification of batch-to-batch variations among uses of reverse-engineering results.
What does Smithers publicly list?
Smithers includes coatings and paints in the material list on its deformulation and reverse-engineering page. Smithers also describes supplier-material checks and monitoring a material’s formulation over time among the needs addressed by that service.
What would our coating report provide?
For our coating projects, we investigate supported component identities and semi-quantitative proportions and deliver an English PDF with a conclusion card, component information, supporting appendix and explicit unresolved portions. The agreement binds both parties to keep sample information, results and business information confidential, except where disclosure is required by law.
We do not promise an exact original recipe from a cured film, and a chemical match alone does not establish equal application or weathering performance.
Our reports are research-grade analytical reports from a laboratory that is not accredited. They cannot be used for product registration or legal proceedings.
Which questions only a test sample can answer?
A public description cannot establish whether your coating’s minor additives are accessible, whether related ingredients separate cleanly or whether a substrate contribution will obscure the target layer. Those are sample-dependent questions, so a shared brief should distinguish the desired decision from the identity level the specimen can actually support. For example, a manufacturer who wants to replace a coating can ask for supported differences between comparable reference and candidate films, then test the proposed replacement in its own application.
Which coating sample can you declare to us before shipping?
We review cured coating films; water-based and powder coatings are reviewed case by case after declaration. Solvent-based and other non-water-based liquids are not received as supplied, so declare the product and propose a cured film or solids fraction for review. Use our industrial inquiry page and shipping guide; ship after agreement, payment and an acceptance number.
FAQ
Does a long component list prove a complete paint recipe?
No; compare the stated identity levels, sample basis and unresolved fractions, because detected signals and confirmed ingredients are different evidential statements.
Should every lab receive the same project brief?
Yes; describe the same specimen, target question and reference role so the resulting scopes address the same decision.
Can a public service page decide whether my wet coating is receivable?
No; ask that laboratory to review the actual physical form and declaration rather than treating a coating-service title as shipment authorization.
Does a matching binder family guarantee a usable replacement?
No; filler, additives and application conditions also matter, so a family-level match provides a development lead rather than proof of equivalent performance.
