Loss Of Material Due To Solvent Evaporation In Resin

Measure it. It's so simple. The amount that you've got at the beginning of the week, minus the amount that you've got at the end of the week, is the amount that has evaporated. Multiply by the value per unit of substance. You must then add in the cost of healthcare and sickness pay for all the employees who have been absent as a result of this extraordinary failure to contain the solvent and either re-use it or dispose of it correctly, the cost of fire prevention methodology and extra insurance to cover against unwanted explosions and then add in the cost of public relations to assure the local community that nothing at all can go wrong go wrong go wrong go wrong....

And that's just cashflow. Nothing in that calculation embraces the share price.

All solvent bearing resins contian a certain percentage of solids. This information is easily obtained.

Simple math will tell you how much of the total, "out-of-can" material will remain after curing/drying the material.

If the resin monomer is the solvent and the mass of resin is a mixture of larger chain polymerized material, and there are modifying long chain aliphatic side chains (the more and the longer = the softer and less brittle = less transparent). So modern polyester resins are like this to try to reduce evaporation of the monomer solvent. If you use epoxies, there can be zero volatiles.

In use, in Canada, you are not allowed to vent solvents, either monomers or inerts. They must be trapped and dealt with. I remember the old reeking polyester boat assemblers.

Even modern car/boat patching kits are formulated to minimize monomer loss by the use of longer chain monomers of lower volatility. This is the sort of 100% solids, zero VOC stuff you describe. Only in China are workers and the environment gassed this way.??
