Momentive Specialty Chemicals Honored With Best Paper Award at the Coating for Africa Show

Tuesday 16. July 2013 - A technical paper that explains the science behind an innovation for paints and coatings from Momentive Specialty Chemicals Inc. ("MSC" or the "Company") was recently honored as the best paper at the Coating For Africa show in Johannesburg, South Africa.

The paper, entitled “Vinyl Versatate Based Latices With High Binding Power and Improved Environmental Performance for Economical Paints,” received the best paper award as judged against more than 32 papers presented at the conference. Chemicals Specialties LTD sponsored the awards.
“Our technical paper provides an introduction about the VeoVa vinyl ester monomer structure and its key benefits,” said Touria Gharrafi, technical service specialist. “It describes how this highly branched hydrophobic monomer enhances the latex and final coating properties, particularly with regard to water and alkaline resistance. By possessing the branched chemical structure, VeoVa monomers can bring an excellent durability to coatings as well.”
The paper describes the development path to produce VeoVa vinyl ester based surfactant stabilized terpolymers for low VOC, low odor interior paints that match the high standard of washability resistance at high PVC levels. “For many years the paint industry has been asking for latices that have a high binding power for matt interior paints to enable them to reduce the amount of binder in the paint,” said Gharrafi.
In order to reach the high binding power requested by paint and coating manufacturers, MSC conducted a study to identify and quantify the different parameters that influence paint scrub resistance. Binder morphology, process conditions, the paint formulation and the test methods used influence the scrub resistance of the paint.
