摘要

Fabrics (I) based on unwoven polyterephthalate weighing 20-70 g/sq. m for coating with dispersions are claimed. Also claimed are (2) coating (I) by spraying, doctor knife, brush or other means; (3) compsns. (II) for coating (I) consisting of (a) aq. dispersions with solids content 42-60 (%) and melamine-, urea-, phenol-HCHO (in text melamine- or urea-melamine-phenol-HCHO) resins as powder or (b) mixt. of dispersions of thermoplastic elastomers, elastomers, and thermosetting resins; (4) applying (II) to (I) by roller coating, spraying, or other means to deposit 50-200g dry material/m2; (5) pressing (I) coated by (II) with wood veneer 0.3-0.6mm thick under 50-300 bar at 15-100 deg.C for 1/2-41/2 minutes; and (6) grinding coated veneer obtd. by process (5) to 0.2-0.45mm thick. USE/ADVANTAGE - Used for prodn. of veneers for pressing to form various motor car, furniture and other parts. Very thin veneers resistant to cracking and breaking during pressing, partic. with curved articles are obtd.
