Series 20HS | Pota-Pox

Generic Type Polyamide Epoxy
Common Usage A high-solids, lower VOC version of Tnemec’s proven polyamide epoxy technology. Provides excellent protection to steel and concrete substrates, and is certified for use in potable water immersion. Excellent choice for tanks, valves, and pipes.
Colors 1211 Red, 1255 Beige, 00WH Tnemec White, 15BL Tank White, 35GR Black and 39BL Delft Blue. Note: Epoxies chalk with extended exposure to sunlight and may yellow on aging. 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 accelerate any potential yellowing.
