DY-14
Acid & Alkali Resistant Coating
Barrier protection for compatible substrates exposed to identified acids, alkalis, salts or process chemicals.
Product overview
Barrier protection for compatible substrates exposed to identified acids, alkalis, salts or process chemicals.
A two-component modified epoxy coating containing ceramic powder, silicon carbide, alumina and flake-shaped acid-resistant fillers for corrosion protection of compatible substrates.
Problems addressed
Acid or alkali contactChemical splash and immersionPermeation through conventional coatings
Selection guidance
How this system differs
Selection requires the actual chemical, concentration, exposure mode, substrate and temperature; a generic corrosion label is not sufficient.
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 roughness; local repair to St 3.
Application Environment
5-60°C; relative humidity ≤85%; substrate at least 3°C above dew point.
Mixing
Mix base and hardener at 3:1 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 10 days.
Precautions
Identify chemical medium and concentration before product selection.
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
Official product source: Acid and alkali resistant anti-corrosion coating / DY-14 source document
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.
