Series 237SC | ChemBloc

Generic Type Modified Polyamine Epoxy
Common Usage A multi-purpose resin for fiberglass reinforced mat (65 mils) or mortar/fiberglass reinforced mat (125 mils) secondary containment systems. Protects against chemicals, thermal cycling, impact and abrasion.
Colors 00GR Gray. Color may not be uniform and is not intended to be finish coat—see Topcoats listed below. Note: Epoxies chalk and yellow with age, extended exposure to UV and artificial lighting. Lack of ventilation, incomplete mixing, miscatalyzation or the use of heaters that emit carbon dioxide and carbon monoxide during application and initial stages of curing may cause amine blush, possibly affecting adhesion of subsequent topcoats. Epoxies will stain with extended exposure to certain acids. As a result, darker colors are recommended.
Surfacer/Filler/Patcher Series 215, 218. Note: A repair kit of 201, with Part C fumed silica, is available for small patching/surfacing repairs (reference Technical Bulletin 99-22). For more extensive repairs and additional information, contact your Tnemec representative or Tnemec Technical Services.
Primers Self-priming or Series 201, 208, 241
Topcoats Series 120-5001, 280, 282, 252SC. Note: A saturant coat of 237SC liquids is required over fiberglass mat prior to application of topcoat.
Volume Solids 100% (mixed)
Recommended DFT Primer: 4.0 to 12.0 (100-305 microns) per coat.
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).
Curing Time
