Roskote A-51 Low VOC Mastic, 1-Gallon Can, by Royston

Totally Resistant to Aliphatic Hydrocarbons. Easiest to Apply (even in severe weather). Multi-Application Versatility For Any Oil/Gas Line Surface. Finest Engineered Thixotropic Viscosity. For use in CA and AZ Royston A51 and Tapecoat TC Mastic are thixotropic, brush applied coal tar coatings for below grade applications. A time proven coating technology for providing corrosion protection to metal fittings, flanges, valves, tanks,mechanical couplings, anode connections and other difficult and irregularconfigurations. They are also designed to protect concrete surfaces fromadverse environments. A51 and TC Mastic are easy to apply by brush or rubber glove. Due to their thixotropic nature they resist drips and sags during application, but will become more flowable the more they are brushed. The A51 and TC Mastic canalso be sprayed via air or airless sprayers. The A51 and TC Mastic may need to be thinned for spray applications below 60°F, contact a Chase Representativefor more details. Recommended UseAppropriate for coating fittings, flanges, valves, tanks, mechanical couplings, anode connections and other difficult and irregular configurations. Their resistance to gasoline and oil make A51 and TC Mastic a good choice for service stations, terminals, bulk stations, producing fields and similar locations. Substrate:  Steel, Stainless Steel, Ductile Iron, Other Metals, FBE, CTE, Concrete Surface Preparation:  SSPC SP-2 Hand Tool Cleaning, SSPC SP-3 Power Tool Cleaning or SSPC SP-6/NACE No. 3 Commercial Blast Cleaning Optional Reinforcement: Royston Glas-Wrap can be applied over the mastic or between mastic layers, giving the coating added strength and impact resistance. Safety:  Refer to Material Safety Data Sheet: MSDS-A51, MSDS-A51-LOW-VOC or MSDSTC-MASTIC Application:  Apply in two coats that each have a WFT of 15 mils. Allow the first coat to dry to the touch before application of the second coat. Never apply more than 40 mils in a single coat to prevent mud cracking.
