Due to its high film forming property and water resistance, EXCEVAL™ is also used for barrier layer of Silicon Release Paper application.
In aqueous gas barrier coating applications, coatings made of EXCEVAL™ absorb significantly less humidity. Therefore EXCEVAL™ provides coatings with excellent gas barrier properties, e.g. toward oxygen, carbon dioxide and various aromas even at elevated relative humidity. Furthermore, the resulting coatings are highly transparent and glossy, have a strong chemical resistance and provide good adhesion to metallization as well as excellent printability.
One additional interesting character is the formation of an excellent oil and grease barrier when coated on papers because of better film forming properties. EXCEVAL™ is an excellent gap filler between paper pulp which results in less permeability of liquids.
EXCEVAL™ is an FDA certified product and can be used in paper coating formulas and will be the best candidate of non-fluoro chemical barrier agents in the next generation of grease proof papers.
