PEARLBOND 700 SERIES: HIGH CRYSTALLIZATION RATE, HIGH TEMPERATURE RESISTANCE

The Pearlbond 700 series offers high-performance alternatives to copolyester and copolyamide adhesives with a very fast cycle time (similar melting behaviour and no surface stickiness), but more elastic and flexible at low temperatures.

  • Excellent adhesion to textiles
  • High chemical resistance
  • High adhesion to rigid substrates
  • Good washing and hydrolysis resistance
  • Very short cycle time due to very high crystallization speed
  • Improved damping, vibration absorption
