Using this specific product
WEG W-Term HPD 36 is listed here as the High-temperature protective coating version for hot surfaces and stacks. 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 High-temperature protective coating; related versions can use different timing.
- For hot surfaces and stacks, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
- Values are for 25°C (77°F). The sheet also lists 10°C and 35°C columns. 7 hours at 10°C and 3 hours at 35°C. 15 hours at 10°C and 6 hours at 35°C. 5 days at 10°C and 3 days at 35°C. 240 hours at 10°C and 168 hours at 35°C.
How to check readiness
Check dry film thickness and the recoat window before the next coat. The sheet gives a pot life of 2 hours. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Lift or move the item gently and avoid twisting the bond or pressing finished faces together.
Avoid this mistake
Recoat windows can close; past the maximum, abrading is usually required.
