Selection guidance

When this product direction fits

Protective systems selected for the actual temperature, thermal cycle, substrate and corrosive exposure.

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

01

Confirm substrate condition, contamination, corrosion, defects and access before work starts.

02

Remove oil, dust and loose material; prepare cleanliness and profile to the reviewed product procedure.

03

Check compatibility of retained coatings and complete a representative trial area when the existing system is uncertain.

04

Prepare and mix only according to the product source; do not improvise ratio, thinner or pot life.

05

Build a continuous system in controlled layers, with special attention to edges, welds, joints and shadow zones.

06

Protect the applied area through curing, then inspect continuity, visible defects and recorded source-backed acceptance items.

Source-specific procedure

01

Surface Preparation

Abrasive blast to Sa 2.5 with 30-60 μm roughness; local repair to St 3.

02

Application Environment

5-60°C; relative humidity ≤85%; substrate ≥3°C above dew point.

03

Mixing

Mix base and hardener at 9:1 by weight for 3-5 minutes.

04

Application Tools

Brush, roller, air spray or airless spray.

05

Curing

At 18°C: touch dry 2 h, hard dry 24 h, full cure 7 days.

06

Precautions

Apply within 8 hours after preparation where conditions permit.

Packaging, storage and transport

PackagingTwo-component, 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.
