Why is checking the density and percent total solids of new latexes important when experimenting with new formulations?
When using a new sample of latex in a formulation it is best to check the density and the percent total solids against the literature before making calculations based on this information. A small variance in either parameter can have significant effects on the formulating process. Oftentimes, both the published density and latex total solids vary from the actual sample. If the latex has been sitting unused for an extended period of time, the latex total solids and density may have changed due to settling. Again, it is beneficial to verify the physical properties before completing formulations.
