FAQ

SelectionCan product selection rely only on the maximum temperature?

No. Continuous temperature, peaks, thermal cycling, medium, substrate, wear and application conditions must be reviewed together.

Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.

Related guide
ApplicationWhy is surface preparation critical?

Oil, salts, rust, weak layers and dust reduce adhesion and can cause early failure even when the coating material is suitable.

Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.

Related guide
SelectionIs a harder wear coating always better?

No. Hardness must be balanced with adhesion, toughness, permeability, impact and thermal-expansion compatibility.

Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.

Related guide
Thermal managementAre solar-reflective coatings the same as thermal insulation?

No. Reflection reduces absorbed solar energy; insulation reduces heat transfer from a hot source or space.

Separate solar gain, process heat, insulation and heat-rejection objectives before choosing a direction.

Thermal managementWhy must pipeline-insulation details be reviewed separately?

Valves, flanges, supports and penetrations interrupt the thermal layer and can create heat bridges, water entry or maintenance conflicts.

Separate solar gain, process heat, insulation and heat-rejection objectives before choosing a direction.

Related guide
ApplicationHow should furnace-lining cracks be handled before coating?

First classify whether the crack is stable, moving or linked to weak lining. Unsound material and active movement must be repaired before a functional layer is considered.

Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.

Related guide
ApplicationCan high-temperature equipment be heated immediately after touch dry?

No. The confirmed cure and any staged heat-up required by the product data must be completed; touch dry does not equal full cure.

Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.

Related guide
Thermal managementHow should roof temperature comparisons be made?

Use comparable locations, the same time window and operating state, documented instruments and ambient conditions. Report the observation boundary without converting it into an unsupported saving percentage.

Separate solar gain, process heat, insulation and heat-rejection objectives before choosing a direction.

Related guide
SelectionDoes a static-dissipative coating replace grounding?

No. The coating is one part of a verified electrical path. Grounding design, continuity and approved testing remain necessary.
