Known as Macromelt OM 673

Features and Benefits

Hotmelt adhesive used for moulding applications with good adhesion for higher temperatures such as automotive underhood. Designed to meet low pressure moulding process requirements.
TECHNOMELT® PA673 is an amber-colored, high performance thermoplastic polyamide and designed to meet low pressure moulding process requirements. Can be processed at low pressure due to its low viscosity, allowing encapsulation of fragile components without damage. Can be used in automotive underhood applications where high service temperature performance is critical - UL-listing (V-0).
  • Solvent-free
  • Easy mouldability
  • Good adhesion to a variety of substrates
  • Excellent moisture resistance
  • Excellent environmental resistance
  • Very short open time
