WebbIt is a slow evaporating solvent that partitions primarily into the polymer phase of a waterborne coating and reduces Minimum Filming Temperature. It can be used with associative thickeners to enhance application properties such as brushability or roll application in high performance coatings. WebbRapidVap® Evaporation System Solutes that are not volatile can be concentrated by drawing the solvent into a gaseous headspace. Two approaches can be used for solvent removal, one being by boiling and the other by directing a stream of (inert) gas over the solvent. In this latter approach, the gas essentially extracts solvent from the liquid ...

WebbPropylene glycol methyl ether (PM) is a fast evaporator and allows for low viscosities.
