Coating Samples and Metamerism: Compare Under Relevant Light Sources
Two samples can match under one light source and differ under another. This is a reason to define lighting in appearance approval.
Gloss Units Are Not a Percentage of Shine
Gloss units are a reference-based measurement scale, not a universal percentage of shine. Interpretation also depends on measurement geometry.
Reflection Haze and Transmission Haze: Choose the Right Optical Question
Reflection haze concerns the reflected image; transmission haze concerns light passing through a material. They address different appearance questions.
Coating Optical Tests: Separate Transmission from Image Sharpness
The amount of transmitted light and the sharpness of an image viewed through a material are different properties.
Coating Haze Reports: Identify Compensated and Uncompensated Values
Some instruments compensate haze values for influences such as background colour. A compensated result is not automatically interchangeable with an uncompensated one.
FTIR Analysis of Coatings: Chemical Information Is Not a Durability Test
FTIR can provide information related to chemical bonds and molecular signatures. It does not by itself measure the coating's service life.
XPS Analysis of Ceramic Coatings: Surface Composition Is Not Bulk Composition
XPS is strongly surface-sensitive. Its reported composition describes the analysed near-surface region rather than automatically representing the entire bottle or film.
Coating XPS Reports: Distinguish Atomic Percent from Weight Percent
Atomic percentage counts relative atoms, while weight percentage describes relative mass. The two quantities are not interchangeable.
Coating Microscopy Images: Keep the Scale Bar and Sample Context
A microscopy image needs scale and specimen information to be meaningful. Magnification alone may become misleading when an image is resized.
Coating Elemental Analysis: Detection Does Not Identify Every Compound
Finding an element does not by itself establish all the chemical compounds containing it. Elemental and chemical-state questions need suitable methods.
TGA for Coatings: Read the Heating Program and Atmosphere
TGA measures mass change under a defined thermal program and atmosphere. Those conditions are essential to interpreting the curve.
DSC for Coatings: Thermal Events Need Technical Interpretation
DSC measures heat-flow behaviour associated with thermal events. A peak or transition needs interpretation in the context of the sample and method.
