Nacure 1051 Dinonylnaphthalene sulfonic acid King Industries Catalyst / Accelerator >> Acid Acrylic/Acrylate Resins Alkyd Resins Epoxy Resins Polyester Coatings >> Solvent-Free/ High-Solids Coatings >> Waterborne Metal 2-Butoxyethanol In order to meet the environmental demands of lower solvent emissions, much of today's high solids and waterborne coatings are based upon low molecular weight resins and amino-formaldehyde crosslinkers. Conversion of these systems into tough, chemically resistant, high performance films at reasonable cure temperatures requires the use of catalysts. Common backbone resins in these formulations include acrylics, alkyds, epoxies and polyesters. Typical amino crosslinking agents include melamines, ureas, glycolurils and benzoguanamines. Reaction of the backbone resin with an amino crosslinker can be greatly enhanced by the addition of the appropriate catalyst. As a result, the reaction between the functional groups of the resin and the crosslinker can be effectively controlled, thus offering: Cure response capabilities from room temperature for acid catalysts and from 65ºC for blocked catalysts Lower cure temperatures for thermoset high solids and waterborne coatings Additionally, the proper choice of catalyst can impart specific desirable properties to the coating including: Improved hardness, gloss, humidity and corrosion resistance Improved mechanical properties King Industries was a pioneer in the development of catalysts and today offers the most complete line of acid and blocked acid (latent) catalysts available. While acid catalysts provide the fastest cure and lower curing temperatures, Nacure 1051 DNNSA 2-Butoxyethanol Best water and corrosion resistance. Recommended for high temperature applications on metal. Acid catalyst. Used in thermoset high solids and waterborne coatings based upon low molecular weight resins (acrylics, alkyds, epoxies and polyesters) and amino-formaldehyde crosslinkers (melamines, ureas, glycolurils and benzoguanamines). Offers cure response capabilities from 125°C. Provides fast cure and low curing temperatures. Gives very good water and corrosion resistance. Recommended for high temperature applications on metal.
