Stays all sealed up – even under extreme stress and strain

322 Pur Pro is a sealant for the true pros. It bonds permanently to materials such as wood, metal, polyester and concrete as well as lightening the workload, as no priming is required. The one-component, polyurethane-based joint sealant can even reliably withstand the challenging conditions in the industrial and construction sectors. Exposure to chemicals and heavy temperature fluctuations and mechanical vibrations – a frequent occurrence on the shop floor – are no problem for this special sealant. Even in high humidity, the material does not show any change. After curing, it remains elastic, meaning it can reliably seal expansion joints over the long term.
