Engineering coatings, and films, are used to protect, preserve and enhance the properties everything from steel signs to stealth ships and from carbon components to Catalytic converters.  The key characteristic to enhanced performance lies in the coating’s barrier properties, or permeability, either to water vapour or one or more of the other common gases

Versaperm’s latest meter measures permeability directly, enabling the most appropriate choice of materials and manufacturing processes to be used.  Measurements can be configured for water vapour, as well as Oxygen, CO2, solvents, hydrocarbons and most other gases.

Accuracy is typically in the parts per million range, (parts per billion for some gases and materials), the meter has a highly automated computerised control and can cope with several samples at a time. As added advantages, the equipment is simple to use, requiring at most minimal training and it can sometimes give results in as little as 30 minutes.  Conventionally gravimetric measurements may take several days or weeks and gives significantly less reliable results.

A permeability testing service is available from Versaperm for companies that don’t have the production throughput to require a dedicated instrument.
