VERSAMID® 125 - ChemCenters

VERSAMID® 125UseVersamid® 125 is a medium viscosity, reactivepolyamide resin based on dimerized fatty acid andpolyamines. This product is designed for use withsolid or liquid epoxy resins to give tough, chemicalresistance, thermoset coatings using roomtemperature cure.Versamid® 125 gives coatings which are generallyharder than Versamid® 140/epoxy formulations andcure more rapidly than Versamid® 140/epoxysystems. It is often blended with fatty amidoamineresin such as Genamid® 250 to give a range ofviscosities, cure speeds and resistance properties.Versamid® 125/epoxy resin systems are used inmaintenance coatings, primers and enamel paintformulation because of their excellent resistanceproperties and adhesion. Versamid® 125 is alsouseful in adhesive applications.Specification Amine Value - mg KOH/gram resin 340 - 370Thermosel Viscosity at 75 °C -poise 6.5 - 9.5Color, Gardner- maximum 8Additional data Amine Value- mg KOH/gram resin 345Viscosity at 75 °C - poise 8Viscosity at 25 °C - poise 400Color, Gardner 6Theoretical Amine HydrogenEquivalent Weight 103Mix Ratio with 190 EEW liquid Epoxy 54 phrDensity8.1 lb/galSeta Flash Point > 200 °F09.03.2009 VERSAMID_r_125_E 1

This may result inan increased viscosity and some foaming whencuring epoxy resins. Therefore, it should be kept intightly closed containers when not in use and storedin a cool, dry place. Properly protected frommoisture, the product has a minimum shelf life ofone year.Versamid® 125 and epoxy resins should not bemixed until just prior to use because a chemicalreaction will take place.Read SAFETY INFORMATION before handling orusing product.Safety InformationBased on toxicological studies with animals,Versamid® 125 causes eye and skin irritation andmay be harmful if swallowed.09.03.2009 VERSAMID_r_125_E 4
