Wettability of Kraft Paper with Biobased Impregnation Resins for the Production of High-Pressure Laminates.

ABSTRACT: High-pressure laminate (HPL) manufacturers are increasingly looking for more environmentally friendly solutions for their production processes to reduce their environmental footprint. Replacing conventional phenol-formaldehyde resins (PF) with sustainable alternatives from renewable resources still remains a challenge to address. The suitability and wetting behavior of an impregnation resin are strongly dependent on its compatibility with the paper used. Thus, kraft papers with varying recycled fiber content were analyzed regarding their chemical composition, structural morphology, and wettability. Recycled paper exhibited a lower surface free energy and increased two-sidedness compared to paper made from virgin fibers, which was attributed to a higher lignin and extractives content as wel
