Supporting the supply chain with coating/ finishing which enable to produce sustainable and high performing material.

Six steps towards a more sustainable future

■  DMF residues left in fabrics after coagulation

■  Residual DMF attacks PU coating -  Reduces hydraulic resistance of fabric -  Typical smell occurs and remains.

■  DMF is toxic and marked as restricted substance
