Paper is one of the most widespread materials on earth, and despite falling oil prices, oil rigs are quite common as well!   Both make use of an extremely wide range of coatings that protect or enhance their surfaces.  As does a huge range of products.

Coatings do this by controlling permeability – which is responsible for everything from rust through to paper's printability and from keeping food fresh to a home's watertightness. Measuring permeability is critical for both for development and QC, which is where Versaperm comes in.  Their latest systems are capable of independently testing the vapour permeability of up to six coatings, samples, components or products at a time, sometimes in as little as 30 minutes. 

In 90 per cent of real world products the key is water vapour permeability, but in some cases (such as with food) it can be Oxygen, Carbon Dioxide, Hydropcarbons or various other gasses.  Fortunately the equipment can optionally measure permeability for all of the world's common gasses.  Small changes to a material or a coating's composition often lead to substantial changes in the finished performance. 

This isn't just important for writing paper, packaging and oil rigs – but with food, pharmaceuticals, seals, clothes, plastics, engineering and even space shuttles.  In all these cases critical performance characteristics are controlled by the permeability.

Versaperm measurement are typically accurate in the parts per million range, (parts per billion with some gasses). 

As well as manufacturing the instruments, Versaperm offers laboratory and consultancy services for companies that only need to test samples on an irregular basis.
