PROJECT DESCRIPTION
PRODUCT PROFILE
Hydroxypropyl carbamate acrylate (HPCA) is a new specialty monomer that is generated by the biotech process. It has several advantages for its use in the manufacture of carbamate based polymers, when compared with conventionally produced material. Hydroxypropyl carbamate acrylate (HPCA) enables crosslinkable carbamate units to be incorporated into the polymer in just one step. HPCA is a new specialty monomer that is generated by the biotech process. It has several advantages for its use in the manufacture of carbamate based polymers, when compared with conventionally produced material.
Processing of Hydroxypropyl Carbamate Acrylate:
The HPCA is generated by the enzymatic trans esterification of hydroxypropyl carbamate and ethyl acrylate. The transesterification of ethyl acrylate with hydroxypropyl carbamate is performed in tank. This involves initially charging hydroxypropyl carbamate (isomer mixture) and ethyl acrylate, and also hydroquinone monomethyl ether. The entire system was inertized with lean air (nitrogen/oxygen mixture with oxygen content 6%). The enzyme reactor connected in the external pumped circulation system comprised of lipase. The reaction was performed at 40° C. and 90 mbar. The ethanol formed was distilled off continuously as an azeotrope with ethyl acrylate by means of a column. Over the entire reaction time of 24 h, a stream of 5 kg/h from the tank bottoms was conducted via the top of the column in order to prevent polymerization.
The conversion was 90% after 24 h of reaction time. Subsequently, the crude product present in ethyl acrylate was washed twice with 1/10 each time of the total volume of water, which removed the unconverted reactant. The pure product obtained was hydroxypropyl carbamate acrylate in a purity of >95% (GC analysis).
Applications of Hydroxypropyl Carbamate Acrylate:
One potential area for application would be adhesives. For example, HPCA 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. HPCA has already proven itself in clear coat 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.
