Omnova Solutions, Fairlawn, OH, USA, has introduced three new pressure sensitive adhesives in the NovaCryl family for the vinyl film, tape and label markets. NovaCryl PS-P 180, PS-V 700 and PS-R 50 adhesives feature varying levels of adhesion, from permanent to ultra-removable, for a range of end uses including graphics, labeling and removable protective films.
Each of the new PSAs is available as a base polymer or a coater-ready formulation, and each is free of alkyl phenol ethoxylate type surfactants.
NovaCryl PS-P 180 water-based acrylic base polymer is designed for permanent PSA applications. It is ideal for clear film label applications, such as those utilized on transparent bottles for shampoo, household cleaners and other toiletries, as well as over-laminates and protective films.
NovaCryl PS-V 700 also delivers a good balance of peel, tack and shear performance. It is FDA 21 CFR, section 175.105 compliant for indirect food contact applications.
NovaCryl PS-R 50 water-based adhesive is an extension of Omnova’s removable PSA chemistry. Maintaining adhesion of less than half a pound, as well as clean removability and UV stability, it exhibits stability and low peel on substrates with both low and high surface energies.
