Coating and laminate defects
The Devil’s in the vapour permeability

Defects such as foam pinholes, streaks, pits, and bubbles are prevalent challenges in coatings and thin laminations. These imperfections not only compromise product performance but also significantly reduce durability. Fortunately, these issues can be quickly identified and addressed with Versaperm's advanced vapour permeability measurement equipment.

Versaperm's cutting-edge technology offers unparalleled precision, exceeding the requirements of modern industry standards. With testing capabilities that deliver accuracies in the Parts Per Million (PPM) to Parts Per Billion (PPB) ranges, our equipment ensures fast and efficient analysis. Additionally, the latest models offer optional pressure and temperature control, alongside the flexibility of either multi-gas or dedicated sensors to identify and diagnose the root causes of coating and laminate defects.

Our advanced systems can test up to six coatings, samples, components or products simultaneously, sometimes delivering initial results within just 30 minutes. Among the common issues that Versaperm equipment can help identufy are:

• Contamination: Dust, dirt, and other particulates that settle on surfaces before application.
• Incomplete wetting: When the coating material fails to fully wet the surface, leading to the formation of pinholes.
• Outgassing: The release of volatile substances or trapped air that causes bubbles, which then pop, creating pinholes.
• Improper application: Poor techniques, such as rapid drying or improper material mixing, leading to defects.

These challenges are particularly critical during high-temperature curing or when applying thick wet films.
Versaperm's equipment and laboratory testing services represent a significant advancement in tackling these industry issues, providing developers and manufacturers with an indispensable tool to achieve product excellence.
