Momentive Specialty Chemicals, a global provider of versatic acid and its derivatives for use in the adhesives and coatings industries, has announced that a new application will be introduced at the American Coatings Show for use in the company’s VeoVa vinyl ester monomer. This show will be taking place from 8 to 10 May in Indianapolis.
Versatic acid’s vinyl ester can be used to make VeoVa monomer and it can be copolymerized easily with acrylates, ethylene and vinyl acetate in order to offer many functional advantages to wood coatings and decorative paints, and to pressure sensitive adhesive (PSA) applications.
Momentive’s President of the Epoxy, Phenolic and Coating Resins division, Joseph Bevilaqua stated that VeoVa monomer has a bulky alphatic structure, hence it offers higher water-resistance and a good stability of adhesive properties like good tack and high shear strength to polymers. Solvent-borne performance is provided by VeoVa monomer when formulated with acrylic PSAs, in a waterborne chemistry, he added.
The company has carried out customer trials and testing, and has found that the VeoVa monomer can provide enhanced performance in numerous PSA applications that contain clear labels, durable labels, paper labels, protective films and specialty tapes.
Higher shear strength, excellent balance in cohesion or adhesion, higher resistance to chemical, humidity, UV, temperature and water are the special advantages obtained from VeoVa monomer.
Three versions of VeoVa monomers namely VeoVa EH, VeoVa 9 and VeoVa 10 are available for a variety of PSA systems, depending on the demands of the specific end user like tack, superior flexibility and increased polymer strength.
