AND BOARD COATINGS
- do they pass the test?
The technical requirements for paper coating have mushroomed in recent
years – “paper coatings” now gets over 1,000,000 hits
on Google! Yet with virtually all of these, the single most important
characteristic is the seemingly simple one of water vapour permeability.
Versaperm Limited is a world
technology leader, produces a WVTR (Water Vapour Transmission) meter,
which provides a quick and simple way to test this all-important vapour
permeability and transmission rate. It can cope with several samples at
a time and can give a reading in as little as 30 minutes – whereas
the conventional gravimetric measurement technique takes several days
and is significantly less accurate.
The WVTR meter is easy to use
and gives a series of digital readouts that can be recorded or simply
read off the LCD screen. It needs no re-calibration and requires, at most,
minimal training to give results that are accurate to better than a few
parts per million (with some samples a few parts per hundred million).
Sensitivities are in the range 0.05 – 3200g/m2/day.
A wide range of variations is available, depending on the specific application,
but both single and multi-sample systems and a variety of chambers are
available for testing samples the size of a thimble up to a pallet load
and beyond. A permeability measurement laboratory service is also available
