TECHNOMELT® PA 673
Known as MACROMELT OM 673
Features and Benefits
A 1-part, black, low-viscosity, high-performance polyamide hot melt adhesive designed for low-pressure moulding applications and incidental solvent exposure. Perfect for higher temperature applications, such as automotive under-bonnet.
TECHNOMELT® PA673 is an amber-coloured, high performance thermoplastic polyamide specially designed to meet low-pressure moulding process requirements. It has a very short open time, and can be processed at low pressure due to its low viscosity, allowing encapsulation of fragile components without damage. Perfect for use in automotive under-bonnet applications, where high service-temperature performance is critical. Operating temperature is 40°C to 140°C (-40°F to 437°F).
- Solvent-free
- Easy mouldability
- Excellent environmental resistance
- Very short open time
- Operating temperature: 40°C to 140°C (-40°F to 437°F)
