An epoxy lining whose immersion wait is 7 days at 75°F but 30 days at 35°F. The guide lists the 55°F column with a typo, so read the temperature in °F.

Using this specific product

Tnemec Series 141 Epoxoline is listed here as the Polyamidoamine epoxy primer and tank lining version for tank lining and steel primer. For coating steel or industrial surfaces, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Polyamidoamine epoxy primer and tank lining; related versions can use different timing.
  • For tank lining and steel primer, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • It is 3 hours at 90°F, 7 at 65°F and 13 at 55°F. Pot life is 2 hours at 77°F and 1 hour at 90°F. It is 4 hours at 90°F and 9 at 65°F. It is 9 days at 55°F and 30 days at 35°F.

How to check readiness

Check dry film thickness and the recoat window before the next coat. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. The guide gives a 7 day maximum for recoating with itself. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.

Avoid this mistake

Recoat windows can close; past the maximum, abrading is usually required.
