BASF is launching the high-performance monomer

July 14/2011

(BASF) -- 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.

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.

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.
