ALTIC SI TOPCOAT is a specialized protective topcoat designed for use as the final layer in the ALTIC SI Thermal Insulation Coating System. It is applied over ALTIC SI Basecoat to provide additional protection against weather, moisture and environmental exposure.
The ALTIC SI system is designed for industrial metal surfaces where thermal insulation, oxidation protection and environmental protection are required. The system consists of three compatible layers:
ALTIC SI PRIMER → ALTIC SI BASECOAT → ALTIC SI TOPCOAT
The SI Basecoat provides the primary thermal insulation function, while the SI Topcoat helps protect the underlying insulation layer and maintain the integrity of the complete coating system.
Key Features & Benefits
- Protective finishing coat for the ALTIC SI system
- Designed for application over ALTIC SI Basecoat
- Helps protect the thermal insulation layer from environmental exposure
- Suitable for compatible industrial metal surfaces
- Provides additional weather protection
- Helps reduce direct exposure to moisture and contaminants
- Supports durability of the complete coating system
- Suitable for outdoor and industrial applications
- Completes the ALTIC SI multi-layer coating system
- Designed for use with compatible ALTIC SI Primer and Basecoat
Role in the ALTIC SI System
ALTIC SI TOPCOAT performs the final protective function in the coating system.
ALTIC SI PRIMER
Provides the foundation over the prepared metal substrate and supports initial oxidation protection.
ALTIC SI BASECOAT
Acts as the primary thermal insulation layer and helps reduce heat transfer.
ALTIC SI TOPCOAT
Provides the external protective layer and helps protect the underlying thermal insulation coating from weather and environmental exposure.

Typical Applications
ALTIC SI TOPCOAT can be considered for use over the ALTIC SI Basecoat on suitable:
- Industrial pipelines
- Steam pipelines
- Process pipelines
- Industrial ducts
- Process equipment
- Industrial vessels
- Carbon steel structures
- Stainless steel equipment
- Low-alloy steel surfaces
- Fire walls
- Outdoor industrial equipment
- Thermal insulation coating systems
Actual suitability depends on the substrate, operating temperature and environmental conditions.
Surface Preparation
ALTIC SI TOPCOAT should be applied over a properly prepared and compatible ALTIC SI BASECOAT.
Before application:
- Ensure the SI Basecoat has reached the required curing condition.
- Remove dust, dirt and loose contaminants.
- Check the basecoat for cracks, defects or mechanical damage.
- Repair defective areas where required.
- Ensure the surface is clean and suitable for topcoat application.
The topcoat should not be applied over loose, contaminated or damaged basecoat.
Application Method
Apply ALTIC SI TOPCOAT according to the latest ALTIC technical instructions.
General Application Procedure
- Confirm that the SI Basecoat is adequately cured.
- Clean the surface to remove dust and contaminants.
- Stir the topcoat thoroughly before application.
- Do not dilute unless specifically permitted by the applicable TDS.
- Apply uniformly using the recommended application equipment.
- Apply the specified number of coats.
- Maintain the recommended interval between coats.
- Allow the complete system to cure before exposure to the intended service environment.
Exact application method, coverage, film thickness, drying time and recoating interval should be taken from the latest product TDS.
Weather & Environmental Protection
Industrial thermal insulation systems may be exposed to rain, humidity, sunlight, dust and other environmental conditions.
ALTIC SI TOPCOAT acts as the external protective layer, helping shield the underlying SI Basecoat from direct environmental exposure.
It can therefore be considered for applications involving:
- Outdoor pipelines
- Exposed process equipment
- Industrial plants
- External ducts
- Equipment exposed to humidity
- Industrial environments with weather exposure
Thermal Insulation Performance
ALTIC SI TOPCOAT is primarily the protective finishing layer and should not be considered the main thermal insulation component of the system.
The thermal insulation function is primarily provided by the ALTIC SI BASECOAT.
Overall system performance depends on factors including:
- Operating temperature
- Basecoat thickness
- Substrate
- Equipment geometry
- Ambient conditions
- Application quality
- Curing conditions
- Complete system configuration
Temperature Considerations
The service-temperature limitation should be considered for the complete ALTIC SI system, rather than for the topcoat alone.
The available ALTIC SI system information specifies a maximum use temperature of approximately 250°C for the complete system.
For applications outside this range, an alternative ALTIC high-temperature coating system should be evaluated.
Maintenance & Inspection
Regular inspection of the completed SI coating system is recommended, particularly on outdoor and continuously operating equipment.
Inspect for:
- Cracking
- Peeling
- Blistering
- Mechanical damage
- Loss of adhesion
- Weathering
- Surface contamination
- Exposed basecoat
Damaged areas should be repaired using the appropriate ALTIC SI system procedure.
Safety & Handling
Use appropriate PPE during application and follow recommended industrial safety procedures.
Ensure adequate ventilation during application. When working around operating hot equipment, conduct an appropriate risk assessment and follow approved site safety procedures.
Refer to the latest Safety Data Sheet (SDS) for detailed information regarding handling, storage, first aid and disposal.
Storage
Keep ALTIC SI TOPCOAT in its original sealed container and store in a suitable cool and dry location.
Protect the product from:
- Direct sunlight
- Excessive heat
- Contamination
- Extreme environmental conditions
For exact shelf life and storage conditions, refer to the latest ALTIC TDS/SDS.
Why Choose ALTIC SI TOPCOAT?
ALTIC SI TOPCOAT provides the final protective layer of the ALTIC SI Thermal Insulation Coating System. It helps protect the underlying thermal insulation layer against weather and environmental exposure while supporting the durability of the complete coating system.
When used together with ALTIC SI PRIMER and ALTIC SI BASECOAT, it forms an integrated coating solution for suitable industrial metal surfaces requiring thermal insulation and protective performance.
