Generic Type
Modified Polyamine Fast-Cure Epoxy
Common Usage
A multi-purpose epoxy coating that can be used as a primer, broadcast, slurry/broadcast, mortar, grout coat, and topcoat. Excellent application properties with good flow and self-leveling characteristics. Protects concrete surfaces from impact, abrasion and mild chemicals.
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.
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: 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.
Topcoats
Series 237, 238, 247, 248, 252SC, 256, 280, 281, 282, 284, 285, 286, 287, 290, 291, 294, 295, 296, 297. Note: If Series 247 (tinted), 248 (tinted), 290, 291 or 297 is selected for the finish coat over a broadcast system, a grout coat of Series 237 or 238 (tinted), 256 (tinted), 280 or 281 is required. If Series 247 (clear), 248 (clear), 285, 294, 295 or 296 is selected for the finish coat over a broadcast system, a grout coat of Series 237 or 238 (clear), 256 (clear) or 284 is required.
Curing Time
| Temperature | To Topcoat/Broadcast | To Place in Service |
|---|---|---|
| 75°F (24°C) | 4 to 8 hours | 16 hours |
Note: If more than 8 hours have elapsed between coats, the coated surface must be mechanically abraded before topcoating. Note: There is no maximum recoat time if aggregate has been broadcast to refusal into the preceding coat. Curing time varies with surface temperature, air movement, humidity and film thickness.
