HOW TO GET TESTY WITH US
Vapour permeability and leakage rate testing for the adhesives industry

Water vapour permeability technology experts Versaperm are offering a fast and economical testing service to determine the often critical permeability and leakage rate of adhesives, mastics and other sealing materials.

Vapour permeability is often a crucial test in an adhesive's or mastic's performance as it can seriously affect the properties of the combined product.

The Versaperm service is unusual in that it cannot only measure both high and low leakage rates very accurately, but can also measure the overall permeability of bonded laminates. Most commonly these are under 50mm thick but the company also has a range of specialist equipment for measuring almost any thickness of material.

The company uses its own-developed WVTR (Water Vapour Transmission) equipment, which can produce accurate and reliable results to better than one part per million - sometimes in the parts per hundreds of million range. With some materials these results can be achieved in as little as 30 minutes, but even with hard to measure foils, results can normally be turned around in a day. Sensitivities are in the range 0.05 - 3200gm/m2/day.

As well as standard testing on products such as adhesives and coatings, Versaperm has the facility to test a wide range of materials and objects such as films and foils, dry coatings, pharmaceutical packaging, bottles, small industrial objects and containers, large industrial objects and even, once, a pizza!
