L216 Curing Accelerator
L216 is a generic accelerator, not only accelerate the curing for epoxy/polyester hybrid powder, but also accelerate the curing for pure polyester system. The effects of improving curing, anti-yellowing are very obviously.
Appearance: white powder
Volatile content: ≤ 0.5%
Used for hybrid or TGIC/polyester powder coating.
Dosage: 0.1-0.7%. Mixed with other materials and extruded.
The gel time is reducing constantly while the dosage of L216 is increasing.
The data is as below:
Gel time for hybrid
Gel time for pure polyester powder
General curing condition: 160° C/10 min
Low temperature curing condition for hybrid: 130° C/30 min, L216 has some selectivity to polyester.
Accelerate curing for hybrid & polyester
Anti-yellowing, excellent flow
Reduce curing temperature
Improve mechanical properties
Store in cool and dry place. Keep away from fire and heat sources.
