Generic Type
Modified Polyamine 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 has very good chemical resistance.
Special Qualifications
Series 237 meets the requirements of LEED-Low-Emitting Materials, Collaborative for High-Performance Schools-Paints & Coatings, WELL Building Standard-VOC Restrictions, and Living Building Challenge–Healthy Interior Performance. Contact your Tnemec representative for more information.
Finish
Gloss
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.
Volatile Organic Compounds
Unthinned: 0.21 lbs/gallon (25 grams/litre)
Thinned 5% (No. 2 Thinner): 0.58 lbs/gallon (70 grams/litre)
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.
Recommended DFT
Primer: 6.0 to 12.0 (150 to 305 microns) per coat.
Broadcast: 1/16" to 1/8" (Double broadcast or slurry broadcast required to achieve 1/8")
Mortar: 3/16" to 1/4” (Minimum of 1/8”, Maximum of 1”)
Grout coat: 8.0 to 16.0 mils (205 to 405 microns)
Intermediate or Topcoat: 8.0 to 16.0 mils (205 to 405 microns)
Curing Time
| Temperature | To Topcoat/Broadcast | To Place in Service |
|---|---|---|
| 75°F (24°C) | 12 to 72 hours | 24 hours |
Note: If more than 72 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.
Number of Components
Liquids–Two: Part A and Part B (2 parts A to 1 part B by volume)
Field Colorant–One: (optional) (Series 820)
Note: Aggregate for mortar applications (S237-0301C) is available from Tnemec or can be purchased from an approved supplier.
Theoretical Coverage
1,604 mil sq ft/gal (39.4 m²/L at 25 microns). See APPLICATION for coverage rates.
