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,
