RAKU® MELT 46-4615

Bonding Technology

Moisture reactive hot melt adhesive (RHM) based on polyurethane prepolymers. After a short open time, the handling strength of the bonded substrates is very quickly achieved. The final curing takes place within approx. 3-5 days, depending on temperature and humidity conditions, to a very flexible elastomer with high cold and heat stability (-40°C to 120°C) and good media resistance.
