The Vinyl Esters of Versatic™ Acid have a unique highly branched aliphatic structure which contributes to the enhancement of key performance properties. Inclusion of the branched Versatic structure in a polymer chain sterically protects the ester bonds of VeoVa™ and of the adjacent monomer units against hydrolysis resulting in greatly improved alkali resistance. VeoVa monomers improve resistance to water and other polar materials as well. Finally, they will not be degraded by UV light and therefore will not cause yellowing.
VeoVa is commonly used in vinyl and acrylic polymers where it improves the hydrolytic stability, adhesion and water resistance dramatically. Emulsion polymers based on VeoVa show a clear improvement in pigment wetting and scrub resistance. Such emulsions can also be used for high quality, low VOC decorative paints and industrial coatings.
VeoVa based emulsions can be easily stabilized with protective colloids or surfactants. The colloid route makes it possible to produce high quality wet or spray dried binders used in a variety of adhesives. Suitable for use in solvent and waterborne systems, its hydrophobicity can offset the water sensitivity created by hydrophilic additives that are sometimes used.
Typical applications that greatly benefit from the use of VeoVa include:
Interior and exterior decorative paints
Water repellent systems
Pressure sensitive adhesives
Redispersible powders and latex concrete admixtures
Textile and nonwoven binders
VeoVa™/acrylic copolymers (VeoCryls)
Pure acrylic emulsions are well known in the marketplace for being high-quality binders. VeoVa monomers significantly upgrade some key performance properties of acrylic coating systems such as adhesion, water resistance, exterior durability and chemical resistance.
While various additives exist to increase the short-term hydrophobicity of coatings, the use of highly hydrophobic monomers that are chemically incorporated into the polymer backbone is an effective way to create a durable and long-lasting barrier against water.
