Overview Burst strength testing is one of the most widely used methods for evaluating the performance of sealed flexible packaging. It applies controlled internal pressure to a package until failure, measuring the point at which the seal or material gives way. For quality managers, R&D specialists, and operations experts working across flexible packaging production, burst…

Definition: Wet coating thickness measurement is the process of measuring the thickness of applied coating or paint layer immediately after it has been applied to a metal coil substrate — before the coated product enters the curing oven and dries. This is achieved using non-contact, optical sensor-based technology positioned inline at the point of application. Why it matters: In coil coating production lines, coatings travel at high…

Color consistency in metal can manufacturing refers to the ability to reproduce a brand's specified colors accurately and repeatedly across every decorated aluminum or steel beverage can - regardless of production run, facility, or geography. In the can-making industry, color is measured using three attributes: hue (the recognized color, such as red or blue), chroma (the vividness or saturation of that color), and lightness (how light or dark the color appears). These are quantified using…

To ensure that paints and coatings are easy to apply and durable in their nature, oils and additives are required. To know that the addition of these components doesn’t adversely affect the composition of your final paint or coating, you need thorough and efficient viscosity testing. Oils and lubricant additives in paint The addition of…

Abrasion testing is a method used to evaluate how resistant a paint, coating, or surface finish is to wear caused by friction, rubbing, or repeated mechanical contact. It measures the ability of a coating to maintain its appearance, adhesion, and protective function when subjected to physical abrasion. Abrasion resistance is a critical quality parameter in…
Key Terms Abrasion Resistance The ability of a coating or surface to resist wear caused by mechanical friction or rubbing. Measured by mass loss, film thickness reduction, or appearance change after a defined test cycle. Taber Abraser A rotating-platform instrument used in abrasion testing (ASTM D4060). Two abrasive wheels are applied to a coated panel under load. Results are…
Overview Abrasion testing evaluates the durability of a paint or coating when subjected to repeated mechanical friction. It is one of the most widely used methods for assessing coating quality because it directly simulates the wear a surface will experience in service - whether that is a wall being scrubbed clean, an automotive panel exposed…
A reference glossary of core terms used in washability and scrub abrasion testing of paints, coatings, and surface finishes. Structured for use across laboratory, quality control, and product development contexts. Washability The property of a dried coating or paint film that allows it to be cleaned repeatedly with water, detergent, or abrasive media without significant…
Overview of washability testing Washability testing evaluates how well a paint, coating, varnish, or ink withstands the mechanical stress of cleaning. It is one of the most widely specified durability tests in the coatings industry, informing product development decisions, quality control processes, and regulatory compliance across architectural paints, industrial coatings, and printed packaging. Understanding washability…
Washability testing is a standardized quality assurance method used to evaluate the resistance of paints, coatings, varnishes, and surface finishes to degradation caused by repeated cleaning or scrubbing. It measures how well a coated surface maintains its integrity, color, and appearance when subjected to wet or dry abrasion over a controlled number of strokes or cycles. Definition…
Scrub abrasion and washability testing is a performance evaluation method used to determine how well a painted or coated surface holds up under repeated mechanical cleaning. For manufacturers of paints, coatings, and architectural finishes, it is one of the most critical tests in the product development and quality assurance process. This article explains the science behind the…
Scrub abrasion and washability testing is a standardized method used to evaluate how well a coated surface resists mechanical wear and repeated cleaning. It measures the durability of paints, coatings, and surface treatments when subjected to scrubbing with a brush, sponge, or abrasive medium in the presence of water or cleaning solution. The test is widely…
Quick reference for quality managers, lab technicians, and coatings formulators. Key Terms Scrub abrasion testing A test method that measures a coating's resistance to mechanical wear when subjected to repeated brush strokes in the presence of an abrasive medium or water. Governed by ASTM D2486 and DIN 53778. Washability testing A related method that evaluates a coating's…
