TQC Sheen Permeability Cups

Developed by TQC Sheen, our paint testing specialist brand, our permeability cups are used to determine the water-vapor transmission of paints, varnishes, coatings, coating systems and related products.  

You’ll find our permeability cups being used wherever there’s a need to inspect water vapor permeability – from coating laboratories to paint production factories.  

It’s important to understand the water vapor permeability potential of your sample products, particularly if they’re made for use in high humidity conditions. The permeability cup (wet cup) is a great way to determine water-vapor transmission. 

What does a permeability cup consist of?

TQC Sheen permeability cups consist of a cup, a seal ring and a cover ring. The seal ring is designed to prevent turning when closing the cover.  

Permeability testing for different coatings

Our permeability cups are suitable for testing both self-supporting coatings and non-self-supporting coatings.  

Quality permeability cup testing  

The TQC Sheen range of permeability cups is designed to support testing to a number of international standards, including ISO 7783, ASTM D1653 and ASTM E96. 

Permeability cup portfolio

Across the Industrial Physics portfolio we have a wide range of paint testing instruments and accessories to offer. 

For example, create a dazzling array of illumination conditions to inspect and color match many types of materials and coatings using our brilliant color assessment cabinets.  

The TQC Dew Point calculator is a handy tool to determine dew point temperature based upon the measurements from the sling psychrometer. It includes a Celsius / Fahrenheit converter. 

A (permeability) cupful of testing insight!

We’re always pleased to share the knowledge we’ve gained over decades of making devices to test inks and coatings. 

In the knowledgebase section of our website you’ll find blogs about subjects related to the product on offer on this page. For example, this one explores how to assess car paint quality. Or perhaps you’d consider this blog that asks manufacturers whether they should switch to water based paints of more interest.
