Surface bonding and lamination
COMPETENCE PUR Surface bonding OR IT S I NAFD H EMS A V IEO N and lamination Surface bondings are used in a multitude of different indus- tries: the building, automotive and furniture industry are only some examples. Depending on the range of requirements, the substrates to be bonded and the technical process, a wide variety of different adhesive systems are available One-component poly- urethane adhesives (PUR) for joint-filling bonding of wood, metal and plastic and even substrates with coarse surfaces - sandwich produc- tion, insulating boards etc. Reactive Polyurethane-HM (PUR) for surface lamination and bonding of various substrates such as wood and wood based materials, plastic, metals or the substrates with each other. Urea and melamine resin adhesives for surface bondings of ve- neers, production of contoured parts made from multi layer veneer and parquet and door production etc. Dispersion on ethylene-vinyl acetate basis (EVA) for lamination of papers or PVC foils (loudspeakers and KLEIBERIT polyurethane furniture). adhesives Dispersion on PVAC basis for bonding of veneer to a KLEIBERIT 1C-PUR 501 KLEIBERIT 1C-PUR 502.8 variety of wooden substrates Liquid adhesive on polyurethane basis for 1C PUR liquid adhesive with short pressing ti- strong bonds of wood, metal and plastics mes for bonding of composite elements such as • water resistance D4 according wood,wooden based materials,metal,plastics KLEBCHEMIE to DIN/EN 204 and many types of foams M.G.
