Calculating the VOC of a Mixture
Q. If I have a base coating that is 490 g/l VOC, and an activator that is 260
g/l VOC, and the mix ration is 3:1, how do I calculate the "as applied" VOC
content?
The VOC content of the mixture is as follows:
| Total emissions for base |
= 3L*490 g VOC/L |
= 1,470 g VOC |
| Total emissions for curing agent |
= 1L*260 g VOC/L |
= 260 g VOC |
| Total emissions of VOC for 4L of mixture |
= 1,470 g+260 g VOC |
= 1,730 g VOC |
| VOC for 1L |
= 1,730 g VOC/4 L |
= 432.5 g VOC/L |
Hope this helps.
Best wishes,
