VeoVa 9 Monomer

Description

VeoVaTM 9 Monomer is the vinyl ester of VersaticTM Acid 9, a synthetic saturated monocarboxylic acid with a highly branched structure containing nine carbon atoms. Its structure may be represented as:

Veova structure

R1 and R2 are alkyl groups containing a total of 6 carbon atoms. VeoVa 9 Monomer, a low viscosity liquid with a typical mild ester odor, is a very attractive monomer for the manufacture of polymers through reactions of the vinyl group. It imparts a combination of high polymer hardness (high glass transition temperature), hydrophobicity and very good chemical and UV resistance.

Application

VeoVa 9 Monomer can be used as a modifying co-monomer in the preparation of vinyl acetate based polymer latices, which are used for the manufacture of specialty emulsion paints. VeoVa 9 Monomer is also used as a co-monomer with acrylates for the production of emulsion, solution and bulk polymers.

Examples of VeoVa 9 vinyl ester based polymer applications are:

  • Specialty emulsion paints, such as glossy emulsion paints and varnishes, water repellant coatings, anti-corrosion paints and coatings for polyolefins,
  • Acid or anhydride-cured acrylic automotive coatings,
  • Acrylic powder coatings. 

On the basis of its typical performance properties VeoVa 9 Monomer is considered interesting for exploring a range of high-quality and industrial paint applications additional to those already listed above.
