High-Temperature Thermal Insulation Coating
Thermal-management materials for equipment, pipework and building assemblies where heat-transfer control is required.
Product overview
Thermal-management materials for equipment, pipework and building assemblies where heat-transfer control is required.
An inorganic nano-binder coating containing ceramic microspheres, silica gel powder, inorganic fibres, potassium titanate whiskers and rare-earth oxides for high-temperature insulation service.
Problems addressed
Heat loss from high-temperature equipmentComplex shapes that are difficult to insulateHigh-temperature external surfaces
Selection guidance
How this system differs
This series manages heat transfer; it does not replace a structural repair, leak repair or corrosion-control system where those problems are active.
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.
Product features and advantages
Low thermal conductivity
Suitable for thick-film application
Applicable to metallic and refractory substrates
Water-based tool cleanup

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
Metal: remove oil, rust, scale and old organic coatings; Sa 2.5 or St 3 for local repair. Non-metal: remove coke, dust and loose material.
Application Environment
5-60°C; relative humidity ≤85%; substrate at least 3°C above dew point.
Mixing
Single-component paste; stir thoroughly before use.
Application Tools
Brush, trowel, scraper or texture application.
Thickness per Coat
Build thickness in multiple coats; do not apply the full thickness in one pass.
Curing
Allow each coat to dry fully; minimum 72 h final drying before service.
Packaging, storage and transport
PackagingSingle pail, 20 kg
StorageCool, dry and ventilated area; 5-40°C
Shelf Life12 months
TransportProtect from unsuitable temperature and contamination

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.
