Nanolok Technology
For High Barrier Applications

What is it?

Pioneered by InMat® Inc., Nanolok™ coatings start as aqueous suspensions of nanodispersed silicates in a polymer matrix. They are environmentally friendly, and can be applied via standard coating processes to rubber substrate. Nanolok™ technology provides the highest gas barrier of any polymeric coating available on the market today.

InMat’s Air D-Fense™ 2000 coating using Nanolok™ technology in a butyl rubber matrix is used commercially in Wilson’s Double Core Tennis Balls – the Official Ball of the Davis Cup. These tennis balls last twice as long because they retain air longer. A thin layer of Nanolok™ on the inner rubber lining of these balls increases air retention compared to the uncoated rubber. The same technology, in a polyester matrix can be used in packaging application to significantly increase oxygen barrier.

What are the benefits?

  • Reduced material costs
  • Reduced weight
  • Thin coating highly cost effective vs. butyl rubber
  • Selectable matrix for optimal secondary properties
  • Compatible with rubber processing conditions
  • Flexibility
  • Recyclability
  • Environmentally friendly

How does it work?

The Nanolok™ aqueous suspension is applied via roll (or dip, or spray) coating process onto a rubber substrate or other substrate. Once dry, a thin coating (10-30 microns) of Nanolok™ forms on the substrate.

This coating contains hundreds of nanodispersed platelets per micron of coating thickness. These platelets form a tortuous path for molecules such as oxygen and aromatics, dramatically increasing the barrier properties of the substrate. Nanolok™ coatings form an extremely efficient barrier which can be 100’s of times less permeable than the uncoated substrate.
