Hot Melt, Open Time and Setting Time
Smithers uses the latest PAPT 3 Instrument to determine the open time and setting time of hot melt adhesives.
The PAPT3 instrument mimics the hot melt bonding operation at commercial speeds. Various combinations of glues and substrates can be characterised for compatibility with the actual process operation, without the need for production down time.
The PAPT3 machine is available for purchase from Smithers.
