New 2K PU Brochure
Content
⏹100 % Coatings based on bio-based polyols (application: pipeline coating) ⏹Super high-solid flexible coating with excellent adhesion on PVC
(application: truck tarpaulin coating)
⏹Water-borne coatings showing fast drying performance,
early block resistance and high hardness
What do natural oil based polyols (Sovermol®) offer to polyurethane coatings/adhesives manufacturers?
⏹Bio-based Polyols (polyfunctional alcohols) based on
renewable raw materials like rapseed oil, Castor oil,
soybeen oil etc. treated with technologies like
epoxidation followed by ring-opening,
transesterification, ethoxylation or propoxylation
⏹Unique properties:
⏹Improved hydrophobicity;
low sensitivity towards moisture
⏹Low viscosity
⏹High chemical stability
⏹Broad adhesion spectrum
⏹Very low shrinkage
⏹High pigment loading with good self levelling
properties …EASY to APPLY“
⏹Solvent free – ZERO VOC
Construction kit approach to customer needs
