Εποξικό σύστημα R9330/H9054 (Γρήγορο)

Εποξικό σύστημα R9330 / H9054 για αναρρόφηση και injection με γρήγορο σκληρυντή

Kάθε κιλό περιλαμβάνει 0.82 κιλά ρητίνης + 0.18 κιλά σκληρυντή

Το R9330 είναι ένα σύστημα δύο συστατικών ειδικά σχεδιασμένο για αναρρόφηση και injection. Είναι πολύ λεπτόρευστο σε θερμοκρασία περιβάλλοντος. Οι δύο διαφορετικοί σκληρυντές (H9052 και H9054) επιτρέπουν το καλούπωμα μικρών και μεγάλων αντικειμένων, και προσφέρουν γρήγορο ξεκαλούπωμα, υψηλές μηχανικές ιδιότητες, καλή τιμή, και αντοχή σε θερμοκρασία μέχρι 80 ^oC (Tg 1).
