Carboline Thermaline 4001 is a single-component, high performance coating which has outstanding resistance to wet/dry cycling conditions at elevated temperatures. Film is internally reinforced with a combination of aluminium and micaceous iron oxide (MiO) flake for superior barrier and thermal shock resistance.
While it is typically used to protect steel substrates under insulation operating up to 649°C, it can also be used on non-insulated steel surfaces. It can handle cryogenic exposures and will cure effectively at ambient conditions to provide corrosion protection without additional heat curing. It has excellent chemical resistant properties to handle the corrosive effects of wet insulation under thermal cycling conditions. This product is recommended for CS-6 and SS-5 systems of NACE SP0198 Standard Practice for coatings to control corrosion under insulation (CUI).
Two coats are recommended for optimal performance.
For best results keep maximum dry film thickness below 300 microns
Maximum Service Temperature:

These times are based on the recommended dry film thicknesses. Excessive film thickness or inadequate ventilating conditions after application require longer dry times and will cause premature failure in extreme cases
Note: To maximize performance, avoid rapid temperature excursion for the first heat cycle; particularly early in the cure. A gentle heat rises through 260°C is preferred. At elevated service temperatures film will harden, yet still provide protection
Surface Preparation
Preparation
General:
All surfaces must be thoroughly cleaned to remove dirt, grease, mill scale, loose rust and any other contaminants that can reduce adhesion via SSPC-SP1 solvent cleaning along with the recommended surface preparation as referenced below
Ferrous Metal:
For optimum performance, abrasive blast to SSPC-SP10 (NACE No.2) to obtain a 60-90 microns blast profile.
Where blasting is impractical or not permitted use hand power tools to prepare surface to SSPC-SP11 or SSPC-SP15 to obtain a 25-50 microns
A better cleaning method will improve performance and service life
Stainless Steel:
Surface profile should be a dense angular 1-3 mils and is best achieved through abrasive blasting
Remove all contaminants that would interfere with the performance of stainless steel for the intended service such as, but not limited to, imbedded iron or chlorides
Application Methods
Product Information
Mixing:
Power mix to uniformity
When desired add Thermaline Heat Shield Part B (Fortifier HT) as follows: Small unit in pint can (EX): 5.12 oz/1 gal Large Unit (AT) in quart can: 0.2 gal/5 gal
Thinning:
Thinning not normally required for spray application. For applications over hot surfaces (up to 260°C) conventional spray is the preferred method of application
For small areas or touch up use a brush and thin up to 10% by volume with Thinner 10 for normal temperatures or up to 10% with Thinner 235 for hot surface applications
Use of thinners other than those supplied or approved by Carboline may adversely affect product performance and will void product warranty whether express or implied
Conventional Spray:
Pressure pot equipped with dual regulators, 3/8" ID minimum material hose, 0.070" fluid tip with appropriate air cap. Adjust air pressure to provide uniform spray pattern
Airless Spray:
Pump Ratio: 32:1 (min)
Volume Output: 2.5 gpm (11.5 lpm) min
Material Hose: 1/2" ID (12.5 mm) min
Tip Size: 0.017-0.021" (0.043-0.053 mm)
Output PSI: 1500-2000 (105-140 kg/cm2
Brush and Roller (General):
Use a natural bristle brush applying in full strokes
Avoid re-brushing
If rolled, use a short nap roller with solvent resistant core. Avoid rerolling
Appearance will vary using brush or roller application methods due to the orientation of the aluminium flake

This product simply requires the substrate temperature to be above the dew point
Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate
Special application techniques may be required above or below normal application conditions
