Resins and composites for the transport industry
The transport industry is an essential sector in our country and GAIRESA is one of its main suppliers in the field of resins, coatings and adhesives. The objectives of energy efficiency and pollution reduction that the automotive industry has been facing for several years have led manufacturers to opt for solutions such as reducing the weight of vehicles, which indirectly favours the reduction in fuel consumption.

More and more manufacturers are incorporating composite materials in their new models, made of epoxy resin and glass fibre or carbon fibre, which are much lighter than metals and, unlike thermoplastics, offer very high mechanical resistance. Otras ventajas del uso de materiales compuestos frente a los metales son: diseño personalizado, fácil sensorización o resistencia a la corrosión. El carácter ignífugo es muchas veces una propiedad innegociable para las resinas empleadas en el sector transportes.

BEPOX COMPOSITES IGNÍFUGO |
Medium viscosity, high tenacity epoxy resin with very good resistance to flame propagation. |
GAIDUR P IGNÍFUGO |
2K solvent based aliphatic polyurethane with maximum resistance to weathering and very good resistance to flame propagation. |
The transport sector is not all about private vehicles. The bodies of commercial vehicles, goods transport vehicles (railways, trailers) and passenger transport vehicles (buses, trains) use hybrid materials that require strong and durable adhesive bonds between metals such as aluminium or steel, plastics such as ABS, PVC, PMMA or insulating foams and natural materials such as wood. GAIRESA‘s range of structural adhesives offers a choice between the versatile epoxy adhesives of the LARBOND® EP series, the tough polyurethane adhesives of the LARBOND® PU series and the fast and strong methacrylate adhesives of the LARBOND® 3001 MMA series.

In order to adapt to the production processes, the manufacture of composites must be fast and agile, and therefore some traditional processes such as manual lamination or infusion are not common in this sector. GAIRESA‘s catalogue of epoxy resins and fibres includes systems adaptable to the technical requirements of each type of process in the automotive sector: RTM, SMC or BMC, among others. Our team of technicians will guide you in choosing the most suitable product.
