durability class D3. Two-component EPI (emulsion polymer isocyanate) adhesives have been tried and tested in applications that require durability class D4, in particular [...] provides adhesives from D3 dispersions according to EN 204/205 for interior applications with short-term water exposure or high humidity to D4 dispersions for interior [...] to which it will be exposed during use. A comprehensive portfolio of powerful D4 dispersions and EPI dispersions helps processors meet the different requirements

could be a health concern. For example, Jowat has successfully developed D3 and D4 dispersion adhesives with significantly reduced formaldehyde emissions compared

optimized manufacturing process has made it possible to develop high-performance D3 and D4 dispersion adhesives whose formaldehyde emissions are 80 % lower than those
