Water-Bead Photographs: A Camera View Does Not Automatically Measure Contact Angle
A photograph of rounded droplets can illustrate appearance without providing a valid contact-angle measurement. Perspective, baseline visibility and the analysis method determine whether a numerical angle can be supported.
Surface-Tension Results: State Whether the Interface Is Liquid-Air or Liquid-Liquid
A tension measurement must identify the two phases at the interface. A liquid-air result and a liquid-liquid result should not be merged under one unexplained property label.
Wetting-Test Temperature: Record the Specimen Condition, Not Only the Room Setting
A room setpoint does not automatically establish the temperature of a specimen brought from another environment. Record the conditioning method relevant to the wetting test before comparing samples.
Droplet Test Sequences: Do Not Reuse a Wetted Location Without a Defined Method
Placing a new test drop on a previously wetted location may not reproduce the original surface condition. Use the method's location and sequencing requirements rather than assuming each drop is an independent fresh measurement.
Coating Free Films and Coated Substrates: Different Specimen Constructions
A free film and a coating attached to a substrate can answer different technical questions. Identify the specimen construction before applying a result to an installed protective system.
Coating Test Fixtures: Check That the Holder Does Not Enter the Measurement Area
A specimen holder should support the test without becoming part of the measured surface unintentionally. Review contact points, shadows and the instrument footprint before collecting coating data.
Coating Rheometer Reports: Record Geometry and Gap
A coating rheology comparison should identify the measurement geometry and gap, alongside the result. Missing setup details can make an apparently precise comparison difficult to reproduce or assess.
Coating Rheology: Preserve Pre-Shear and Recovery History
The preparation sequence before a rheology measurement belongs in the test record. Two nominally identical samples may not have experienced the same handling, conditioning or waiting period.
Coating Surface Measurements Before and After Cleaning: Use a Paired Location Plan
A before-and-after cleaning comparison needs a location plan that accounts for any effect of the first measurement. Measuring nearby but unrecorded spots can confuse local variation with the cleaning response.
Coating Support Response Time: Separate Acknowledgement from a Useful Technical Reply
An automated acknowledgement and a useful technical response are different events. Measure them separately if the aim is to understand how quickly customers receive actionable coating support.
Coating Support Resolution Time: Keep Customer Waiting and Internal Work Visible
A support case can remain open while waiting for photographs, product information or a technical review. Record these stages so the total duration can be understood without hiding the customer's elapsed experience.
Repeated Coating Support Contacts: Count Cases and Messages Separately
Several messages can concern one coating issue. Keep message count separate from case count so support demand and complaint frequency are not confused.
