Structural bonding of exterior components & interior of rail vehicles
On the outside, GFK structures are glued to the steel wagon box. Due to the component size and different material properties, the adhesive joint must be elastic but high-strength. 1- and 2-component polyurethane adhesives are used. The two-component technology ensures the curing of large adhesive beads without additional humidity.
Some of the materials are qualified by OEMs and large railway operators and tested according to EN45545-2.
3M™ Double Coated Tape GPT-020F3M™ Double Coated Tape GPT-020F have high instant adhesion, high temperature and humidity resistance and excellent shear performance. The tapes bond to many high surface energy substrates and some low surface energy substrates, including stainless steel, HDPE, ABS, acrylic, PP, polycarbonate, aluminium or glass. The tape is suitable for various markets and applications including POP/POS displays, light boxes, sports equipment, indoor and outdoor signs, furniture trim attachment, mounting of electronics or plastic parts.
3M™ Scotch-Weld™ 2-part acrylic based adhesive DP8005/DP80103M™ Scotch-Weld™ acrylic based adhesives withstand extreme temperatures, develop strength quickly and feature high impact and peel resistance. They are suitable for bonding most plastics, aluminum, steel, lightly oily metal surfaces, and low surface energy plastics (PE, PP, TPE). 3M™'s acrylic based adhesives are quick and easy to apply and provide bonds that replace metal fasteners for improved aesthetics. 3M™ acrylic adhesives are available in low-odor and non-flammable versions. Among 3M™'s most popular construction adhesives are the 3M™ Scotch-Weld™ DP8005 and 3M™ Scotch-Weld™ DP8010.
3M™ spray adhesives3M™ spray adhesive are suitable for OEM to on-site construction fabrication. 3M™ spray adhesives are suitable for bonding to metal, high-pressure laminate (HPL), plastic, insulation, foam, fabric, wood, MDF and a wide range of other substrates. 3M™ spray adhesive offer many advantages, including being very efficient on large surfaces, being quick to apply, convenient and easy to use, eliminating equipment maintenance and other costs. One of the most popular spray adhesives is 3M™ Super 77™ Multipurpose Spray Adhesive.
3M™VHB™ Tape Series3M™VHB™ Tape Series are high performance double sided tapes made from 100% closed-cell acrylic foam. The tapes exhibit with a high initial tack, have excellent bonding properties with high tensile and shear strength, have high temperature-, weathering-, UV- and solvent resistance and conformability and bond materials with rough or smooth surfaces, too. 3M™ VHB™ tapes are suitable for many materials and are used today in a wide variety of markets such as rail and commercial vehicles, electronics, windows and doors, household appliances and in the construction, aerospace and furniture industries.
Agomet® 2-component methyl methacrylate adhesivesDeveloped for processing with hardener powder or hardener paste to ensure easy mixing.
Araldite® 2-component methyl methacrylate adhesivesFor all high-strength yet tough elastic adhesive joints. Very high tolerance to poorly bondable substrates or surfaces that are not optimally prepared.
BETAMATE™ 1-component polyurethane structural adhesivesAir humidity curing 1-component polyurethane adhesives and sealants for high-strength, permanently elastic adhesive joints with accelerated curing.
