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 guideApplicationWhy 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 guideSelectionIs 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 guideThermal 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.
Related guideSelectionCan tank interiors and exteriors use the same coating system?
Usually not. Immersion media, outdoor weather, solar exposure and maintenance access require separate review.
Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.
Related guideInspection & maintenanceCan an existing coating be overcoated directly?
Only after adhesion, compatibility, contamination and defect extent are checked. Loose or incompatible areas must be removed.
Record the original condition and inspect the same high-risk locations over time.

Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.
Related guideSelectionWhy do marine steel structures corrode faster?
Salt, high humidity and wet-dry cycling accelerate corrosion at scratches, edges, welds and thin-film areas.
Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.
Related guideApplicationWhy must equipment be degreased before spraying?
Oil reduces adhesion and can create craters, fish-eyes and local detachment.
Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.
Related guideInspection & maintenanceWhen can coated equipment return to service?
After the specified cure for the material, temperature, humidity, film build and exposure. Touch dry alone is not sufficient.
Record the original condition and inspect the same high-risk locations over time.
Related guideSafetyWhat is required for confined-space coating work?
Gas testing, forced ventilation, suitable lighting, fire control, personal protection, supervision and rescue planning are required.
Follow the site risk assessment, safety data and approved work controls for the actual material and location.
Related guideSelectionWhat information should be sent to DAYU-X for technical review?
Provide equipment, substrate, continuous and peak temperature, medium and concentration, wear condition, existing problem, access and project country.
Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.
Related guideThermal 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 guideApplicationHow 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 guideApplicationCan 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 guideThermal 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 guideSelectionDoes 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.
Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.
Related guideInspection & maintenanceWhat should be recorded during an annealing-furnace shutdown?
Record lining, joints, radiant tubes, supports, deposits, deformation and previous repairs before cleaning, with repeatable locations for later comparison.
Record the original condition and inspect the same high-risk locations over time.
Related guideInspection & maintenanceWhy are tank welds and supports priority inspection zones?
Their geometry can retain moisture, reduce coating thickness and concentrate movement or handling damage, so preparation and stripe coating require special control.
Record the original condition and inspect the same high-risk locations over time.
Related guideApplicationWhy is one very thick coat not a substitute for the specified layer build?
Excess build can trap solvent or water, sag, cure unevenly and reduce intercoat control. Apply within the confirmed per-coat and recoat requirements.
Project-specific mixing, film build, recoat and cure requirements must come from the approved product source.
Related guideSelectionWhy must concrete moisture and cracks be assessed together?
Cracks can be water paths and moisture pressure can affect repair and coating adhesion. The source, activity and substrate strength determine the repair sequence.
Confirm the medium, temperature, substrate, exposure and maintenance boundary before selection.
Related guideSafetyWhat production records support coating batch traceability?
Incoming-material checks, batch instructions, process conditions, in-process inspection, finished-product release, filling identification and retained samples should form one traceable chain.
Follow the site risk assessment, safety data and approved work controls for the actual material and location.
