Baerlocher introduces stabilizers for DCOIT containing PVC coatings

Baerlocher, a producer of additives for the plastics industry, has launched new liquid mixed metal stabilizers for PVC coatings protecting against microbiological degradation. The new stabilizers named Baerostab UBZ 635 XLP RF and Baerostab UBZ 782 XLP RF trigger a chemical challenge associated with DCOIT and thus enables the industry to manufacture PVC products that comply with the latest EU regulations on biocides.

Baerlocher, a producer of additives for the plastics industry, has launched new liquid mixed metal stabilizers for PVC coatings protecting against microbiological degradation. The new stabilizers named Baerostab UBZ 635 XLP RF and Baerostab UBZ 782 XLP RF trigger a chemical challenge associated with DCOIT and thus enables the industry to manufacture PVC products that comply with the latest EU regulations on biocides.

Biocides are widely used for products as sunshades, truck tarpaulins and textile architecture to avoid product degradation by biological effects caused by fungus, mold, and microorganisms. In textile coating, biocides are essential to prevent mold.

Starting in mid 2012, a new EU regulation on biocidal products came into force, which must be fully applied since the end of 2013. As a result of the revision, many of the previously used biocides are eliminated and are more and more replaced with DCOIT.

DCOIT, however, leads to an undesirable chemical reaction with the components of standard stabilizers reducing their efficiency. The new liquid mixed metal stabilizers Baerlocher has now developed are compatible with DCOIT, avoid this undesirable chemical reaction and therefore can be dosed in the same way as the previous systems.

"The development team of Baerlocher is committed to provide our customers with highly innovative stabilizer solutions to ensure compliance with latest industry requirements, legal regulations and policies," said Stefan Fokken, head of research and development. "We are pleased that we were able to proof our high innovative strength even in this case. That is one of the reasons why our customers trust us worldwide."
