New nanocomposite barrier coatings

February 8, 2011

InMat, a manufacturer of high barrier nanocomposite coatings, has introduced the Nanolok WR water-based barrier coating product line. Nanolok WR 20135 provides a high oxygen barrier over the widest relative humidity range currently available in water-based nanocomposites, the company said. Nanolok WR 301409 provides a new level of direct adhesion to a wide variety of flexible packaging films including many polyolefins. This will enable customers to reduce the number of layers in their barrier packaging. After drying this coating has shown resistance to incidental contact with water, and will maintain its barrier properties after top coating and or application of water-based inks, the company said.
