Glues, adhesives, sealants, coatings

Glues, adhesives and other sealants surround us on a daily basis and we find them in different ranges depending on the desired end use:

  • conventional glues that do not require very high performance, for example aqueous vinyl glues (wood glue), acrylics (glue for plastics), neoprene, etc.
  • semi-structural adhesives with high mechanical performance, for example, adhesives and adhesive mortars for tiles, PVC adhesives, phenoplast, etc.
  • high-performance structural adhesives that allow parts or materials to be firmly assembled on all supports (metal, concrete, glass, wood, etc.), for example epoxy (or epoxy), polyurethane, cyanoacrylic, polyimide adhesives, etc.
  • natural glues such as vegetable resins, animal glues, starch derivatives, etc.
  • specific adhesives such as Hot Melt Pressure Sensitive Adhesive (HMPSA), hot melt adhesives, silicones, etc.


Adhesives can also be classified according to their use:
