Thermal Insulation Energy-Saving 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.
A water-based insulation coating using hollow glass microspheres as the primary functional filler with water-based and inorganic nano binders.
Problems addressed
Heat loss from pipework and equipmentHot surface temperatureComplex shapes requiring a conformal insulation layer
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
Single-component paste
Multiple application methods
Water 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 to Sa 2.5 or St 3; non-metal substrate dry, sound and free of dust or cracks.
Application Environment
5-60°C; relative humidity ≤85%; substrate ≥3°C above dew point.
Mixing
Stir the single-component paste thoroughly.
Application Tools
Brush, trowel, scraper or texture application.
Thickness per Coat
Build in multiple coats; avoid excessive one-pass thickness.
Curing
Allow at least 72 h before service.
Packaging, storage and transport
Packaging15 kg/pail
StorageCool, dry and ventilated area; 5-40°C
Shelf Life12 months
TransportKeep sealed

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.
