Measuring the permeability of mastics and adhesives
Measuring the vapour permeability of a mastic or adhesive (or seal) is simple with our new permeability measurement equipment, although sometimes it requires a specific additional jig.
The equipment quickly and reliably measures the permeability
and diffusive flow of vapours across
the mastic, seal or adhesive barrier - which can be a sample of the mastic or adhesive or a component with the mastic or adhesive in place,
Our new permeability meter allows you to measure vapour permeability
for a wide range of gases, including O2, N2, He, Hydrocarbons gases and water vapour.
The permeability meter needs no re-calibration, is simple to use and can achieve accuracies of better than one part per million (with some samples a few parts per hundred million).
We also provide a comprehensive permeability testing
An enormous range of Sealants and Adhesives is in widespread daily use. In many applications and situations one of the critical factors for a mastic or adhesive is its ability to prevent the ingress or exit of water, hydrocarbons (usually in vapour form) or other gases. This requires a measurement of the permeability the adhesive or mastic – which could be Non Silicon sealants, Expanding PU Foams, Gap filling Adhesive, PU Adhesives, PVA and contact Adhesives, Specialist Tapes, Acetoxy or a Neutral Silicone.
