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
