DY-16 high-temperature wear-resistant ceramic coating package

High Temperature Wear and Erosion Protection

DY-16 is a high temperature wear resistant coating for compatible waterwall tubes, economizers, superheaters and other hot industrial surfaces exposed to particle erosion. The ceramic system is intended for conditions where heat, oxidation, thermal shock and wear must be reviewed together. Boiler erosion protection is highly location-specific: particle loading, gas velocity, flow direction, ash characteristics, tube geometry and local temperature all influence where material loss occurs. Selection should therefore use equipment inspection and operating information rather than the product name alone. DY-16 has a different high-temperature application intent from DY-15, which is positioned primarily for chutes, hoppers, silos and general material-handling wear.

A modified organosilicon and low-melting amorphous glass coating with zirconia, boron nitride, silicon carbide and ceramic fillers.

Problems addressed

High-temperature wearThermal shockOxidation and corrosion at high temperature

Particle Erosion at High Temperature

When this product direction fits

Protective coating systems for equipment exposed to abrasion, particle erosion and combined corrosive service.

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.

DY-16 vs DY-15 Selection

DY-16 owns the high-temperature wear intent for compatible boiler and heating surfaces. DY-15 addresses abrasion and erosion on material-handling equipment. Confirm the actual temperature and damage mechanism.

Application and Inspection

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.

Frequently Asked Questions

How can boiler tubes be protected from particle erosion?

Inspect and map the affected zones, identify particle-flow conditions, then review a compatible high-temperature coating system, preparation, application and inspection plan.

What causes waterwall and economizer wear?

Particle loading, velocity, impact direction, ash characteristics, gas flow, tube geometry, temperature and corrosion can all contribute to localized material loss.

When is high-temperature ceramic wear protection required?

It may be considered when verified inspection and operating data show combined elevated temperature and particle erosion on a compatible substrate.
