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.
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.
Base Coats
Series 252SC. (For a flexible basecoat option, refer to Series 206SC product data sheet.)
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.
