Monday''s Ask the Experts question from a cleaning professional on the International Custodial Advisors Network (ICAN) "Ask the Experts" page: What are the technical differences between low solids and high solids finishes? Can high solids be made to shine like a mirror? What level of solids is best for highest level of shine?
The solids content for the majority of finishes generally varies from 16 percent to 22 percent, with a growing interest in higher solids up to 30 percent to 32 perecent levels. The solids level is the amount of material left (polymer film, waxes, plasticizers, leveling resins, etc.) after everything volatile has left the film, (water, co-solvents, etc.).
The higher the solids content, the more temperamental the application may become, and it may require a bit more finesse to achieve a smooth, wet film. Because the thickness of the film is greater, the water and solvents have to travel a greater distance to escape and this can often extend the drying/curing time needed before the coating is ready to resist ... — Gary Clipperton, president of National Pro Clean Corporation.
