Volume Solids
Theoretical 89% (mixed). Series 252SC 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
Resinous Basecoat: 6.0 to 12.0 mils (150-305 microns).
Mortar/Slurry Basecoat: 60 to 80 mils.
Saturant: 8.0 to 12.0 mils (200-305 microns).
Topcoat: 4.0 to 12.0 mils (100-305 microns).
Curing Time
| Temperature | To Topcoat | Place in Service | Full Cure |
|---|---|---|---|
| 75°F (24°C) | 6 to 72 hours | 24 hours | 72 hours |
If more than 72 hours have elapsed between coats, the ChemBloc coated surface must be mechanically abraded before topcoating. Note: A 24 hour cure provides for traffic, secondary containment and certain mild chemical exposures. Contact your Tnemec representative or Tnemec Technical Services.
Volatile Organic Compounds
Unthinned: 0.2 lbs/gallon (23 grams/litre)
Base Coats

Number of Components
Resin Containment Kit (RCK)–Two: Part A (base) and Part B (catalyst)
Mortar Containment Kit (MCK)–Three: Parts A (base), B (catalyst) and C (aggregate)
Topcoats
Series 252SC. Note: A saturant coat of 252SC liquids is required over fiberglass mat prior to application of topcoat. However, when Series 206SC flexible basecoat is used, then a 237SC or 239SC saturant coat is required. Note: Topcoats listed are suitable for Series 252SC chemical exposure.
