HB Fuller / Kommerling 1C and 2C PUR-Adhesives

HB Fuller / Kommerling offer a variety of innovative adhesive systems to meet the unique requirements of the individual elements comprising multi-layered sandwich panels.

Sandwich panels that form the side and rear walls, roofs, floors, and doors of commercial and recreational vehicles use a variety of light-weight materials, including fibreglass, aluminium, steel, and foams. Increased efficiency in production, stability, thermal insulation, light-weight construction and acoustic dampening are all critical factors for this competitive market.

Using HB Fuller / Kommerling adhesives when constructing sandwich panels provides highly durable bonds and guarantees long-lasting functionality, contributing to the overall performance of the panels in the finished vehicles.

HB Fuller 1-component polyurethane (1C PUR) reaction adhesives will harden at room temperature for bonding and sealing a variety of materials such as GRP, wood-based materials, untreated, primed and painted or anodized metals, as well as many plastics, and foams. HB Fuller 1C PUR adhesives react with moisture to form elastic bonds and are best suited for applications where thermal expansion must be taken into account.

Kommerling 2-component polyurethane (2C PUR) reaction adhesives will harden at room temperature for bonding a variety of surfaces such as GRP, wood-based materials, untreated, primed and painted steel and aluminium sheets, many plastics and foams based on PS, PU, and PET. Kommerling 2C PUR products consist of a resin and a hardening component that are mixed at a fixed ratio, and harden into structural or semi-structural adhesives, regardless of humidity. They are also particularly suitable for applications involving large surface areas.

Key features include:

  • Strong bonding that is temperature and water resistant
  • Long-lasting elasticity and reduction of vibration
  • Product formulation specific to application method and requirements

Kommerling Korapop STP Assembly Adhesives

Recent years have seen dramatic changes in the styling and manufacturing of trucks, trailers, caravans, and motorhomes. The mix of materials used to fabricate these vehicles has also radically changed. Using fibreglass composites and sandwich panel structures is now commonplace, resulting in reduced vehicle weight, improved fuel economy, better durability, enhanced thermal insulation, and user comfort.

However, traditional fixing methods such as screwing and riveting can result in damage to the sandwich panel structures. Repairing problems such as buckling, deformation and denting require significant labour time and expense. Using adhesive bonding to assemble the panels eliminates these risks and increases rigidity, reduces weight, and improves the insulating qualities of the panel.

Kommerling offers a range of high-performance bonding solutions for body assembly. Kommerling’s silane-terminated polymer (STP) technology, combines the performance of traditional polyurethane systems, and provides additional benefits such as reduced substrate preparation and improved worker safety.

Kommerling’s Korapop (STP) 1-component adhesives harden at room temperature for bonding and sealing a variety of substrates such as GRP, wood-based materials, untreated, primed and painted or anodized metals, as well as many plastics. These products are formulated to react with moisture, forming permanent elastic bonds and are best suited for applications where thermal expansion must be taken into account.

Key features include:

  • Adhesion to a wide range of substrates
  • Good wet tack
  • Solvent-free
  • Exceptionally high UV and weather resistance
  • Permanently elastic
  • Can be painted over
  • Fast and bubble-free curing
  • Available in white, grey, and transparent
