Selection guidance
How this system differs
Unlike a general anti-corrosion coating, this series is selected where particle movement, abrasion or impact is a primary design factor.
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
Abrasive blast steel to Sa 2.5 with 30-60 μm surface roughness; local repair to St 3.
Application Environment
5-60°C; relative humidity ≤85%; substrate at least 3°C above dew point.
Mixing
Mechanically mix base and hardener at 9:1 by weight for 3-5 minutes.
Application Tools
Brush, roller, air spray or airless spray.
Curing
Touch dry 2 h, hard dry 24 h, full cure 7 days.
Precautions
Apply promptly after surface preparation and avoid overnight exposure before coating.
Packaging, storage and transport
PackagingTwo-component, 20 kg/pail
StorageDry, cool area; protect from sunlight and heat; 5-40°C
Shelf Life12 months unopened
TransportKeep sealed and within the stated storage range

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.
