Selection guidance
How this system differs
The selection is driven by documented service temperature, thermal cycling and corrosive exposure rather than temperature alone.
What must be confirmed
Suitability depends on the actual substrate, medium, concentration, temperature cycle, exposure mode and application window. Final system selection and project-specific instructions require technical review.

Project application guidance
Confirm substrate condition, contamination, corrosion, defects and access before work starts.
Remove oil, dust and loose material; prepare cleanliness and profile to the reviewed product procedure.
Check compatibility of retained coatings and complete a representative trial area when the existing system is uncertain.
Prepare and mix only according to the product source; do not improvise ratio, thinner or pot life.
Build a continuous system in controlled layers, with special attention to edges, welds, joints and shadow zones.
Protect the applied area through curing, then inspect continuity, visible defects and recorded source-backed acceptance items.
Source-specific procedure
Surface Preparation
Metal to Sa 2.5 or St 3 for local repair; non-metal surfaces clean and free of coke, dust and loose material.
Application Environment
5-60°C; relative humidity ≤85%; substrate ≥3°C above dew point.
Mixing
Single-component: stir until uniform. Two-component: mix powder:liquid at 1.8-2:1 by weight for 3-5 minutes.
Application Tools
Air spray or airless spray, 30-40 cm from substrate.
Curing
24 h stated in application section.
Precautions
Do not use organic solvent thinners or tools contaminated by oil-based coatings.
Packaging, storage and transport
PackagingSingle- or two-component form; 20 kg/pail
StorageDry, cool area away from sunlight, heat and ignition sources; 5-40°C
Shelf Life12 months unopened
TransportMaintain 5-40°C

Quality checks
Check surface-preparation records, environmental conditions, layer continuity, edges, welds and visible defects. Use only acceptance criteria stated in the reviewed product or project documents.
Maintenance and repair
Inspect representative high-risk locations during planned maintenance. Clean the area, identify the cause of damage, feather sound edges and verify compatibility before local repair.
Scope and limitations
Suitability depends on the actual substrate, medium, concentration, temperature cycle, exposure mode and application window. Final system selection and project-specific instructions require technical review.
