Application
Packaging and barrier coatings.
Screening coating and thin-film variants where barrier-adjacent behavior, adhesion-relevant response, optical appearance, surface durability, and supplier process windows interact.
Physical screen
Barrier-adjacent questions need a wafer map before coated-film samples.
Selected library region
Measured wafer positions narrow the barrier or packaging question before follow-up coatings.
Uniform coated samples
Selected coating directions can be repeated as separate sample pieces for supplier or scale-up discussion.Decision problem
Packaging coatings often need several properties to move together.
Barrier-adjacent behavior, adhesion-relevant response, optical appearance, surface durability, and supplier process windows can trade off quickly. xemX can use screening to compare physical coating variants or make selected prototype samples before supplier trials or scale-up validation.
Customers can bring a coated-film, supplier-sample, surface-layer, or scale-up question where a smaller physical screening campaign can produce a measured shortlist for the next trial.
Screening campaign
Compare related coating or material variants to choose samples for supplier trials, coated-film tests, or scale-up discussion.
Prototype coating project
Start from a narrower coating, substrate, stack, or supplier question and make small-format coated samples when the route fits.
What can be measured
Optical response, adhesion-relevant indicators, conductivity where relevant, hardness, corrosion or chemical response, phase, structure, or surface change.
What comes back
Coating variants worth supplier trials, variants to rule out, measured property maps, sample recommendations, and physical coated pieces when scoped.
xemX can identify packaging and barrier coating variants worth making again. Food-contact compliance, converting trials, full shelf-life validation, and production scale-up usually remain downstream.
