Product introduction:
L216 accelerator
L216 is a general-purpose accelerator, both to promote epoxy/polyester hybrid powder curing and pure polyester system curing, improve the curing effect is obvious. And it promotes the curing of the powder does not affect the leveling, does not produce yellowing, mechanical properties have been greatly improved. It is a better promoter at present.
1.Technical Parameters
Appearance:white powder.
Volatile matter:≤0.5%.
2.Applications
L216 is suitable for hybrid or TGIC/polyester type powder coatings.
3.Usage
Add directly to the powder formulation components and mix to extrude.The recommended dosage is 0.1~0.5%.
In hybrid and pure polyester powders with the increase of L216 addition gelling time continues to shorten,the data are shown in the table below:
| 1 | 2 | 3 | 4 |
|---|---|---|---|---|
Powder dosage | 100g | 100 | 100 | 100 |
L216 dosage | 0g | 0.1 | 0.3 | 0.5 |
Variation of gelation time of hybrid powders | 150s | 89 | 77 | 55 |
Variation of gelation time of pure polyester powder | 110s | 75 | 29 | 21 |
flow out | leveling | leveling | leveling | leveling |
mechanical property | good | good | good | good |
It may be seen from the table that with the addition of the accelerator L216, the gelling time keeps decreasing while the leveling does not change, so that the curing time of the powder can be shortened or the baking temperature can be lowered.
4.Product Characteristics
（1）This product has good catalytic effect and thermal stability, does not affect the leveling does not produce yellowing.
（2）It can be used for indoor and outdoor various powder coatings.
（3）Small dosage, less dosage can achieve the powder curing requirements.
（4）This product is a flowable powder, making it easier to use.
5．Packaging & Storage
