BASF launches new specialty monomer HPCA

  • Successfully used in clearcoat systems with cost-efficiency  and processing benefits
  • Acrylate monomer with free carbamate group for a broad  range of applications
  • Industrial implementation of a white biotechnology process for manufacturing new specialty monomers

Ludwigshafen, Germany – July 13, 2011 – BASF is launching the  high-performance product hydroxypropyl carbamate acrylate (HPCA), a crosslinking acrylate monomer. The new specialty monomer  shortens the processing time for the manufacture of carbamate based polymers. Compared with currently existing processes, HPCA enables  crosslinkable carbamate units to be incorporated into the polymer in  just one step. The usual two-step procedure is no longer necessary. In  addition to the shorter manufacturing process, HPCA also offers  positive features for applications. 

Successfully used in clearcoat systems  HPCA has already proven itself in clearcoat systems for the  automotive industry. One-component coatings with HPCA achieve a  comparable performance level to two-component coatings, for example with regard to weather and scratch resistance. In contrast to  two-component coatings, one-component coatings are easier to use in  applications and are more cost efficient

Potential for a wide range of applications
What’s especially interesting for developers: “Due to its special chemical  structure with the free carbamate group, HPCA offers additional potential  for a broad range of applications in the future. With our expertise and  decades of experience, we are offering to work in partnership with our  customers to develop new areas of application”, says Dr. Boris  Breitscheidel, Business Manager Specialty Monomers. One area would  be adhesives, for example. These can be hardened either thermally or  using UV light. Here the free carbamate group can have a positive  impact on both adhesion and cohesion, in this way making it possible to  improve adhesive properties.

Industrial implementation of a white biotechnology process for manufacturing new specialty monomers  BASF researchers have successfully manufactured the specific chemical  structure of HPCA on a commercial scale with the help of white  biotechnology. In the biocatalytic procedure, the specialty monomer is  synthesized by applying an enzyme. From HPCA the carbamate-based  polyacrylate can be produced then in one step. BASF has used this  procedure in industrial production for the first time.
