Product Overview
Hallstar designs and manufactures specialty ester chemistry for polymer modification. The EXXATE® products, produced by Hallstar for over a decade, are high purity acetate esters used as cosolvents and tail solvents in coatings. Hallstar’s Acetate Esters are high performance leveling and flow aids that are desirable alternatives to standard solvents. These esters are synthesized predominantly from branched aliphatic, primary alcohols in the C6 to C13 carbon range. Esters Key Attributes:Powerful solvents across a range of resins, miscible with most common organic solventsSlow, controlled evaporation rates with full release from paintPromotes gloss through improved flow and levelingLow surface tension for good substrate wettingLow water miscibility for blister preventionLonger pot life of moisture cure PU & improve blush resistanceNon-HAPS, low density for lower VOC contentIn acrylic polymerization, less initiator required, higher gloss and impact resistanceMolecular Weight 144Specific Gravity 0.874Evaporation Rate 0.11Vapor Pressure(20C) 1.4Surface Tension 26Water Solubility(Ester in Water) 0.02Hazardous Air Pollutant(HAPS) NoPackagingBulk - 44,000lbs275 gallon tote - 2000lbs55 gallon drum - 400lbsGlobal Compliance:ChinaEUUSAPolymers:PolyurethaneAcrylic resinsEpoxy PolyolUrethane AcrylateNitrocelluloseMethyl methacrylatePolyacrylatePolyester resinPolymethyl methacrylateApplications:CoatingHigh Solids CoatingMaintenance CoatingMarine CoatingAutomotive top coatPolymerization SolventAgricultureAdjuvantsPesticidesAcid neutralizer Hallstar Industrial Hallstar Industrial Solvents,Processing aids,Flow/levelling agent,Acetate esters Paints coatings and inks,Pharma and medical,Agri chemicals and fertilizers
