What's the Uses Of Paper Coatings?

Paper has become one of the most useful, and widely used materials on the planet. Much of this diversity is due to the myriad physical properties of coatings - from strength to printability and from jam-free running to electrical conductivity.
By far the most useful property of the coatings is permeability and this, through Versaperm's latest range of paper permeability measurement instrumentation, is the key to developing and checking new coatings and applications.
Permeability controls not just the "feel" of the finished product, but also how printable it is, its strength, mechanical handling, barrier characteristics and many other properties. Small changes to a coating's composition can lead to substantial changes to the properties of the finished product.
Now, thanks to Versaperm, measuring this for quality control or as part of the development process has become fast and easy - not only with respect to water vapour but for every other other commonly used gas - including oxygen, solvents, volatiles, nitrogen and CO2.
Versaperm's sensor range has also been expanded with the addition of mass spectrometer and semiconductor sensors. These latest options add unprecedented flexibility and accuracy to the equipment.
Accuracies are typically in the parts per million range, (parts per billion with some gasses). Conventional gravimetric and other techniques usually produce far less consistent results - and Versaperm's latest equipment and sensors take from as little as 30 minutes to produce a reading and it can measure several samples at a time.
As well as manufacturing the instruments, Versaperm offers laboratory and consultancy services for companies that only need to test samples on an irregular basis.
