Waterborne coatings industry giant, Cortec Corporation, has recently developed a unique waterborne moisture barrier coating. Sources reveal that this innovative coating is expected to give the paper manufacturers the ability to create effective, non-toxic, environment friendly paper and corrugated-board substitutes for polyethylene and wax papers.
For the record, waterborne coatings make use of water (over 80%) as a primary solvent to disperse a resin, making these coatings easy for application and eco-friendly with VOC content not more than 3.5 pounds per gallon of water.
By applying the so-called EcoShield barrier coating onto the recycled paper, linerboard, and Kraft paper, the paper industry manufacturers will be able to produce fully re-pulpable and recyclable paper that provides excellent resistance to moisture, grease, and oil, states the company report.
Earlier, polyethylene and wax coatings, according to sources, have been the most commonly used coatings in the waterborne coatings industry that were used in manufacturing seal porous paper, sheets, and corrugated boxes to provide a moisture-vapor barrier. However, the resulting paper product did not have the capability to be recycled through normal channels and was thus adding further to environmental problems.
However, Cortec’s EcoShield barrier coating, as per sources, has stood out against this environmental concern, while achieving commendable low moisture vapor transmission rate (MVTR) in comparison to the polycoated or waxed paper.
Sources reveal that Cortec’s waterborne coating not only protects paper’s physical properties such as tensile strength, folding endurance, burst, tear, and coefficient of friction, but also provide protection against leakage or packaging failure of items with slippery or greasy characteristics.
Industry experts speculate that post launching this eco-friendly coating, Cortec will be able to significantly expand its footprints in the global waterborne coatings market share and further broaden its applications in packaging, construction, metalworking, electronics, oil and gas, water treatment, and other industries.
