Dusseldorf, Germany – Bayer MaterialScience unveiled what it says is the first bio-based cross-linker for polyurethanes at a press conference yesterday – 15 January, 2015.
The company also said its pentamethylene diisocyanate (PDI) is a new isocyanate with a 70% carbon content from biomass that does not generate any direct competition for food production.
Daniel Meyer, head of the coatings, adhesives, specialties business unit and member of the executive committee of Bayer MaterialScience, said the company's recent innovation also includes the world premier of PDI derivative as hardener for coatings and adhesives.
Meyer told journalists and industry experts the company intends to bring the first PDI-based product to market in April 2015 with commercial manufacturing to follow in 2016 with an annual capacity of up to 20kT – enough to coat 20m cars, he said.
In the separate innovation, the company has developed a thermolatent hardener that enables energy and cost-efficient mixed-material automotive coating for first time, he said, adding that the paint shop process in automotive manufacturing is currently the most expensive part of car manufacture.
The material is the result of a collaboration between BMS, the German research organisation Fraunhofer Institute and DURR – a machinery and plant manufacturer based in Bietigheim-Bissingen, Germany.
The topcoats cure up to 30% faster than with established two-component polyurethane coatings and, in the medium term, will most likely be suitable for the mixed coating of plastic, composite and metal substrates, said Meyer.
The collaboration aspect of the innovation is in line with BMS’ strategy for developing new products, said Meyer. “Our objective is to incorporate our partners along the value chain and their know-how into our development efforts as early as possible to ensure that our customers are successful in the market.
“We will increasingly offer material solutions resulting from development partnerships,” he added.
The innovation will be officially unveiled at the European Coatings Show in April.
