ALTIC SI Coat System is an advanced, water-based thermal insulation and anti-oxidation coating specifically engineered for high-temperature metal protection. This innovative system offers long-term resistance against heat, oxidation, corrosion, and gaseous chemical reactions on metallic surfaces operating up to 200°C under insulation and 400°C at primer level. Unlike conventional insulation materials that require shutdown and dismantling, ALTIC SI can be applied online, directly on operational equipment—making it the ideal choice for industries seeking uninterrupted production and long-term thermal efficiency.
This three-component coating system includes:
- ALTIC SI Primer – A high-temperature sealer that creates a sealed-porosity layer to prevent oxidation.
- ALTIC SI Basecoat – A thick, insulating layer applied using a texture gun to reduce surface temperature and energy loss.
- ALTIC SI Topcoat – A durable weather-resistant coating providing UV, moisture and environmental protection.
Key Features & Benefits
✔ No Shutdown Required – Applied Online
No need to halt production or equipment operation. The coating is specially formulated for application on hot surfaces, drastically reducing downtime and maintenance costs.
✔ Thermal Insulation & Energy Savings
Reduces surface temperature by up to 70–80°C. Example:
- Uncoated Surface: 141°C
- Coated Surface: 62°C
This results in a significant drop in radiation and convection heat losses—over 5000 kcal/hour saved in the sample area test.
✔ Oxidation & Corrosion Protection
Forms a sealed, inorganic protective layer that prevents oxidation, scaling, and metal surface degradation during thermal cycles.
✔ Fireproof & Non-Flammable
An inorganic, water-based formulation that does not catch or spread fire—ensuring enhanced workplace safety.
✔ Eco-Friendly & Sustainable
- Up to 85% recycled content
- Produces 10x less energy during manufacturing compared to traditional insulation
- No glass fiber, mineral wool, or carcinogenic components
- Free from VOCs and hazardous solvents
✔ Weather & Moisture Resistant
Suitable for both indoor and outdoor use. Resists moisture, UV exposure, and environmental wear.
✔ No-Itch Application & Safe for Workers
Unlike glass wool or ceramic fiber insulation, ALTIC SI is non-itchy and safe to handle without health hazards.
Applications
ALTIC SI Coat System is ideal for:
- Hot pipelines (steam lines, process lines)
