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™ monomer 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 monomer is commonly used in vinyl and acrylic polymers where it improves the resistance to water, UV light, adhesion dramatically. Such polymers can also be used for high quality, low VOC decorative paints and industrial coatings.
VeoVa vinyl ester 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 monomer include:
- Industrial coatings
- Interior and exterior decorative paints
- Water repellent systems
- Wood glues
- Pressure sensitive adhesives
- Construction adhesives
- Redispersible powders and latex concrete admixtures
- Textile and nonwoven binders
- Elastomeric roof coatings
VeoVa™ vinyl ester / 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.
