A new standard for industrial hygiene – without any compromise.

Planning straightforward by cross-linking. Why not?

“Ultra line” is the name of an innovative range of high-performance crosslinkers made by Covestro. As an advancement of existing products, it will replace a large part of our current portfolio – keeping the quality up and your business future-ready.

The new ultra line – pretty straightforward:

  • meeting future regulations already today
  • with a residual monomer content below 0.1%
  • improving industrial hygiene as well as workplace safety

Advancing by persisting.

Continuous process improvements for products you can rely on.

Our ultra line products are not just state-of-the-art, they are technically equivalent to our existing products. Successfully tested over the past and compared with the former status quo, the quality of the product range has not changed in any way – except for the residual monomer content specification. Ultra line can be used in the same broad range of applications as its Desmodur® and Bayhydur® predecessors.
