Series 239 | ChemTread

Generic Type Modified Novolac Polyamine Epoxy
Common Usage A highly chemical and heat-resistant, multi-purpose, broadcast, slurry broadcast or mortar applied floor topping system installed at 1/8” to 1/4” thickness. Protects against impact, abrasion, heat and harsh chemicals.
Colors Clear or pigmented. Can be factory or field-tinted (Series 820 Field Tint) in 16 StrataShield colors and certain custom colors. Contact your Tnemec representative for additional information. Note: Colors may not be uniform and are not intended to be finish coats—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. Caution: Novolacs will stain with extended exposure to certain acids. As a result, darker colors are recommended.
Surfacer/Filler/Patcher Series 206, 215. Note: A repair kit of 201, with Part C fumed silica, is available for small patching/surfacing repairs. For more extensive repairs and additional information, contact your Tnemec representative or Tnemec Technical Services.
Primers Self-priming or Series 201, 203, 241
Topcoats Series 252SC, 282, 286. Note: Drier mixes, typically used for power trowel application, should be grouted with Series 239 prior to the finish coat application.
Volume Solids 100% (mixed)
Recommended DFT Primer: 6.0 to 12.0 (150-305 microns) per coat.
Broadcast: Minimum 1/8”. Requires two broadcast applications at 1/16” each or applied as a slurry broadcast.
Mortar: Suggested 1/4” (Minimum of 3/16”, Maximum of 1”)
Curing Time
Temperature To Topcoat Place in Service Full Cure
75°F (24°C) 8 to 24 hours 12 to 24 hours 5 days
If more than 24 hours have elapsed between coats, the ChemTread coated surface must be mechanically abraded before topcoating. Note: 24 hour cure provides for traffic, secondary containment and certain mild chemical exposures. Up to five days cure is required for certain severe chemical exposures. Contact your Tnemec representative or Tnemec Technical Services.
