- Intended applications
For Under Insulation applications where severe corrosive environments can °Ccur such as salt water immersion & acid exposure in elevated temperatures. Such facilities include, petr°Chemical, chemical plants, offshore, power, refining, and generic pr°Cessing; pipework, vessels, tanks, heat exchangers, stacks, chimneys, steamlines etc. operating within -196 to 650°C temperature range.
- Application methods
Airless, airspray and brush & roller
- Substrate temperature & conditions
Ambient substrate temperature application should remain between 10 to 50°C and remain 3°C above the dew point and relative humidity should be 35 - 85% during application. For various temperature applications thinning is:
- Thermaguard™ X21; 10 to 60°C
- Thermaguard™ S100; 60 to 150°C
- Thermaguard™ S200; 150 to 260°C
- Application
Airless
Pump: 30:1 or higher
Tip size: 0.015 - 0.023 inch
Pressure: 2321 - 2901 psi / 160 - 200 bar
Thinning:
Thermaguard™ X21, 10 to 60°C (2 - 5%)
Thermaguard™ S100, 50 to 150°C (5 - 10%)
Remove all mesh filters.
Airspray (conventional)
Pressure: 30 psi / 2.1 bar
Nozzle orifice: 1.8 - 2.2mm
Thinning: Thermaguard™ X21, 10 to 60°C (4 - 8%)
Thermaguard™ S100, 60 to 150°C (6 - 10%)
Thermaguard™ S200, 150 to 260°C (8 - 12%)
Brush/roller
Thinning:
Thermaguard™ S100, 60 to 150°C (0 - 10%)
Thermaguard™ S200, 150 to 260°C (8 - 12%)
For elevated temperature application, be sure that brush bristle and roller nap are tolerant of the substrate temperatures.
Mixing
Thermaguard™ CUI 650 is a single component product, settling can °Ccur during transport & storage. The material should always be mixed using a mechanical agitation ensuring all settled-out pigments are dispersed until a uniform consistency is reached.
Reactivity
Thermaguard™ CUI 650 is reactive with moisture, skinning can °Ccur once opened. To prevent skinning keep covered at all times.
Reducer
Thermaguard™ X21 (10 to 60°C application)
Thermaguard™ S100 (60 to 150°C application)
Thermaguard™ S200 (150 to 260°C application)
Clean up
Use Thermaguard™ X21 for cleaning after product use. Ensuring all material is flushed from application equipment.

Technical Details & Test Data
- Surface preparation
Intended for insulated steel surfaces, both carbon & stainless. Substrates must be clean, dry and free from any contamination. All oil, dirt, grease, dust, foreign material and loose rust must be removed prior to coating.
Insulated or exterior exposed carbon steel
Abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. The resulting surface profile (Rz) should be 30 - 50µm. All sharp edges & rough welds should be rounded off.
Thermaguard™ CUI 650 has surface tolerance to maintenance work applications where tight adhering or flash rusted steel surfaces are present & blasting is not possible. In such circumstances pr°Ceed with the following pretreatment; remove all loose adhering rust & rust scale and follow St 2/3 surface preparation prior to application.
Insulated or exterior exposed stainless steel
Abrasive sweep clean using a non-metallic & chloride free abrasive (aluminum oxide or garnet). The resulting surface profile (Rz) should be 30 - 50µm. All sharp edges & rough welds should be rounded off
- System specifications
Thermaguard™ CUI 650 in a 2-coat application for CUI or exposed corrosion protection as a direct to metal (DTM) coating system. Carbon or stainless steel ambient spray, brush or roller (10 to 50°C) application:
- Thermaguard™ CUI 650: 125 - 150µm DFT
- Thermaguard™ CUI 650: 125 - 150µm DF
Application of Thermaguard™ CUI 650 by airless or airspray are the preferred application methods when applied over Sa 2½ prepared carbon steel or abrasively swept stainless steel (Rz >30µm). New build applications should adopt a stripe coating method to ensure edges have adequate film build.
Maintenance application (St 2/3), brush & roller (10 to 50°C) application:
- Thermaguard™ CUI 650: 75 - 125µm DFT
- Thermaguard™ CUI 650: 75 - 125µm DFT
- Thermaguard™ CUI 650: 75 - 125µm DFT
At higher temperature applications, further coats maybe necessary to build the film to a total 250 - 300µm DFT.
