Chemical & Corrosion Resistant Coatings

DY-14

Acid & Alkali Resistant Coating

Q: What coating is resistant to acids and alkalis?

A compatible chemical-resistant coating may be selected after the exact acid or alkali, concentration, temperature and exposure mode are confirmed. DY-14 can then be reviewed against that information.

Q: How do you choose a chemical-resistant coating?

Identify all media, concentrations, temperatures, immersion or splash conditions, cleaning cycles, substrate and required layer sequence before checking product compatibility.

Q: Why must chemical concentration and temperature be confirmed?

The aggressiveness of a chemical environment and the coating response can change with both concentration and temperature, so a generic chemical name is not enough for selection.

Chemical-resistant coating for compatible tanks, pipelines, scrubbers and process vessels exposed to identified acids, alkalis, salts or process media.

Chemical Resistant Coating for Industrial Equipment

DY-14 is a chemical resistant coating for compatible tanks, pipelines, scrubbers, process vessels and containment areas exposed to identified acids, alkalis, salts or other process media. It forms a dense barrier on suitable prepared metal, concrete, brickwork and other substrates listed in the product information. An acid and alkali resistant coating cannot be selected from the chemical name alone: concentration, temperature, immersion or splash exposure, cleaning cycles, contaminants and substrate condition all affect suitability. Confirm the complete chemical environment and intended layer position before specifying the system. Flue-gas and acidic-condensate applications have a different selection intent and should also be reviewed against DY-13.

A two-component modified epoxy coating containing ceramic powder, silicon carbide, alumina and flake-shaped acid-resistant fillers for corrosion protection of compatible substrates.

Selection by Chemical Medium

When this product direction fits

Barrier protection for compatible substrates exposed to identified acids, alkalis, salts or process chemicals.

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.

DY-14 or DY-13?

DY-14 owns the general chemical, acid and alkali barrier intent for identified process media. DY-13 is positioned for flue gas, acidic condensate and gas-treatment environments. Confirm exposure mode and media.

Acid and Alkali Resistant Protection

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.

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.
