Coating Colour Difference: State Which Delta E Formula Was Used
Delta E is not one universally interchangeable calculation. Different colour-difference formulas can produce different numerical results.
Coating Colour Checks: Read the Direction of Change, Not Only Delta E
A single colour-difference value describes magnitude but does not explain the direction of the change. Component differences provide additional context.
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.
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.
Coating Viscosity Reports: Record the Spindle and Speed
A rotational-viscosity result needs its test conditions. Spindle and speed are part of the method, especially for materials whose response depends on shear.
Coating Flow-Cup Tests: Seconds Are Specific to the Cup
A flow time only becomes meaningful with the cup type, orifice and test conditions. Seconds from different cups are not automatically equivalent.
Dynamic and Kinematic Viscosity in Coating Specifications
Dynamic and kinematic viscosity use different quantities and units. Density connects them under the appropriate conditions.
Coating Viscosity Units: Centipoise and Millipascal-Seconds
One centipoise equals one millipascal-second. The equal numerical value does not remove the need for matching test conditions.
Coating Thixotropy: Keep Time Under Shear in the Test Record
Time-dependent flow behaviour requires a time-defined method. An immediate reading and a later reading may answer different questions.
Coating Viscosity Checks: Avoid Air Bubbles in the Test Specimen
Entrained air can interfere with a test specimen's suitability. Sample preparation should follow the instrument and product method.
