Imerys Performance Minerals Europe Announces a Concept for Barrier Coating
Imerys Performance Minerals Europe, has developed new barrier kaolins as part of the BARRISURF™ product line. These hyper-platy, nano-dimensional thickness crystals create a tortuous path through the coating that inherently resists penetration.
With the rising cost of polymers, incorporating Imerys BARRISURF™ kaolins in a formulation is a cost effective route to deliver superior barrier performance.
The increased focus on recycling and sustainable packaging is driving the trend for water-based barrier coatings to replace fluorocarbon and extruded polymer barrier coatings. Platy kaolins incorporated with appropriate polymers can provide effective barrier performance against water, gases and grease. The use of these platy kaolins improve the barrier performance above and beyond typical latex coatings.
