Topcoats Series 252SC
Volume Solids Theoretical 89% (mixed). Series 251SC system contains a reactive monomer and some loss will occur during application and cure. Actual solids by volume will vary depending upon temperature and air movement. See Coverage Rates.
Recommended DFT 4.0 to 12.0 mils (100 to 305 microns)
Curing Time
Temperature To Topcoat
75°F (24°C) 6 to 72 hours
If more than 72 hours have elapsed between coats, the ChemBloc coated surface must be mechanically abraded before topcoating. Note: Curing time varies with surface temperature, air movement, humidity and film thickness.
Volatile Organic Compounds Unthinned: 0.59 lbs/gallon (71 grams/litre)
Theoretical Coverage 1,123 mil sq ft/gal (27.6 m²/L at 25 microns). See APPLICATION for coverage rates.
Number of Components Two: Part A (base) and Part B (catalyst)
