Description

Hot melt adhesives are solvent-free formulations which become liquid when heated and are applied in molten state. To achieve a good degree of wetting, the substrates have to be joined within the open time. Hot melts are characterised by a very rapid build-up of internal strength on cooling. They are physically hardening thermoplastic adhesives which are already present in their final chemical state.
Modern hot melt adhesives from Jowat impress with excellent processing characteristics and a broad spectrum of adhesion to different materials. Short setting times facilitate a fast downline processing and therefore fast production speeds. Jowat supplies a wide range of different high-performance adhesives with special properties, which provide an ideal process solution for even the most specific and complex requirements.

Features

Hot melt adhesives provide the following benefits:

  • a 100 % solids content, free of solvents and water
  • high production speeds due to short setting times
  • a wide range of adhesion to different materials
  • they can level out of irregularities in the surface
  • smooth surfaces due to a water-free bonding
  • elastic bondlines
  • can be reactivated by heat and therefore be used for precoating
  • joint can be opened by heating (recycling)
