PRODUCT DESCRIPTION: Service Temperature: minus 300°F to 1200°F [minus 185°C to 650°C] Surface Application Temperatures: 50°F to 600°F [ 10°C to 316°C]*

• Hi-Temp 1027 is a high-build , single component coating formulated to prevent corrosion under insulation of carbon and stainless stee l.

• Hi-Temp 1027 is formulated to help prevent chloride induced stress corrosion cracking of stainless steel and has been tested by an independent laboratory for low leachable chlorides, sulfides and halides. It helps protect against chlor ides: 1) from the atmosphere, 2) from by-products of process operations, and 3) wh ich may be incorporated in the insulation, from coming in contact with stainless steel.

• Hi-Temp 1027 is a low vac, high build primer which air dries at ambient temperatures to a UV resistant and stable film , and provides excellent corrosion resistance at the full range of service temperatures .

• Hi-Temp 1027 can be top coated with a full range of Hi-Temp color top coats. • Hi-Temp 1027 can be appl ied directly to hot substrates having a metal temperature up to 600°F [316°C]*,

eliminating the need for costly shutdown during maintenance. • Hi-Temp 1027 does not require a heat cure to achieve superior corrosion resistance. • Hi-Temp 1027 is resistant to thermal shock and thermal cycling in intermittent (wet, steam, dry) service. • Hi-Temp 1027 can be applied to tightly adhering rust in maintenance and repair situations. • Hi-Temp 1027 will protect cryoge nic equipment in continuous or cyc lic operation from minus 300°F to 1000°F

[minus 185°C to 538°C] . • Hi-Temp 1027 provides a UV-res istant, chalking-free film with no maximum recoat interval, regardless of .

"-...-/ operating temp erature, as long as the surface to be recoated is clean and free of all contaminants.

HI-TEMP'COATINGS TECHNOLOGY

SURFACE PREPARATION: As with all coatings, the performance and service life of Hi-Temp 1027 are re lative to the quality of surface preparation accomplished.

CARBON STEEL All surfaces to be coated with Hi-Temp 1027 shall be free of all weld splatter , oil, dirt , grease , and all other contaminants, especially salts. Round off all rough welds and sharp edges.

In maintenance and repair situations, Hi-Temp 1027 can be applied over a surface in which tightly adhering rust is still present; remove all rust scale and loosely adhering rust until glints of bright metal are visible. The remaining rust must be tightly adherent and not easily removed by lightly wiping with a cloth.

Hi-Temp 1027 should only be used to overcoat inorganic zinc or itself. When overcoating aged inorganic zinc, prepare a small test patch and check for adhesion. If previously applied coatings other than inorganic zinc or Hi­Temp 1027 are not fully removed by the method of surface preparation utilized, feather the edges of any remaining old coating, and use Hi-Temp 1027 to spot prime only the areas where the substrate is exposed.

Non-insulated surfaces:

• Recommended: Dry abrasive blast clean to SSPC-SP 6, "Commercial Blast" [Sa 2] with a 1.0 to 2.0 mil [25 to 50 micron] profile.

When abrasive blast cleaning is not an option, the following methods are acceptable:

• SSPC-SP 15 "Commercial Grade Power Tool Cleaning", with a minimum 1.0 mil [25 micron] profile. • SSPC-SP 12, "Surface Preparation and Cleaning of Metals by Waterjett ing Prior to Recoating" to meet the

visual definition of WJ-3, "Thorough Cleaning." Use potable water. • SSPC-SP 3, "Power Tool Cleaning" [St 3] or SSPC-SP 2, "Hand Tool Cleaning" [St 2].

Insulated surfaces:

• Recommended: Dry abrasive blast clean to SSPC-SP 6, "Commercial Blast" [Sa 2] or better, with a 1.0 to 2.0 mil [25 to 50 micron] profile.

When abrasive blasting is not an option, the following methods are acceptable :

• SSPC-SP 15 "Commercial Grade Power Tool Cleaning", with a minimum 1.0 mil [25 micron] profile. • SSPC-SP 12, "Surface Preparation and Cleaning of Metals by Waterjetting Prior to Recoating" to meet the

visual definition of WJ-2 "Very thorough or Substantial Cleaning." Use potable water. All existing coating must be removed except for aged inorganic zinc or existing Hi-Temp 1027.

• Power Tool Clean or Hand Tool Clean to remove all existing coating except for aged inorganic zinc or existing Hi-Temp 1027.

STAINLESS STEEL All surfaces to be coated with Hi-Temp 1027 shall be free of all weld splatter, oil, dirt, grease, and all other contaminants, especially salts. Round off all rough welds and sharp edges.

IMPORTANT: DO NOT USE CHLORINATED SOLVENTS ON STAINLESS STEEL SURFACES.

Non-insulated and insulated surfaces:

• Small surfaces may be cleaned with a chloride free solvent. Large surfaces may be cleaned utilizing a high or low pressure wash or steam cleaning with an alkaline detergent, followed by a freshwater rinse. Water used should be potable grade or better and should be checked to assure minimal salt content. Do not use any chemical additives in the rinse water.

• An anchor profile is not mandatory for adhesion of Hi-Temp 1027 on stainless steel surfaces. o As an option, following cleaning, a light abrasive sweep blast using an appropriate chloride free

abrasive may be performed. After completion of this mechanical surface preparation, rinse the surface with potable grade water or better. Always allow rinsed surfaces to dry before coating.

MIXING , THINNING, AND CLEANUP:

Hi-Temp 1027 is a heavy bodied material; use mechanical agitation for mixing immediately before application and as needed during application. Be sure any settled solids are incorporated during mixing. If thinning is needed, thin only with Hi-Temp thinners and in accordance with applicable regulations. Agitate as needed during application.

Application to ambient substrate Below 150°F [66°C]

Appl ication to hot substrate 150°F to 500°F [66°C to 260°C]

Flush equipment and thin with Hi-Temp #10 or #11 Flush equipment and thin with Hi-Temp #5

Clean up with Thinners #5, #10, #11

For application to hot substrates over 150°F and up to 500°F [66°C to 260°C] thin (if needed) only with Hi­Temp th inner #5. For app licatio n to substrates over 500°F and up to 600°F [260°C to 316°C] consult Hi-Temp Technical Service.

APPLICATION:

For ambient application, surface temperature should be a minimum of 5°F [3°C] above the dew point. 0 0 not apply to surfaces with surface temperature below 50°F [10°C] . 00 not exceed recommended maximum dry film thicknesses for the appropriate service type and temperatures.

APPLICATION TO HOT SURFACES:

IMPORTANT! It is essential to apply multiple thin passes of Hi-Temp 1027 during application to hot steel. This process, similar to mist coating, prevents blistering and also allows solvent to escape without leaving pinholes. Use of a so lvent other tha n Hi-Temp #5 thinner could produce a f ire hazard, and dry spray and poor film characteristics may also result. If blisters are observed in Hi-Temp 1027 applied to hot surfaces , immediately brush out the blisters before they set, using a wood-handled china bristle brush. Note that the higher the substrate temperature, the shorter the recoat time.

For direct application to ho t substra tes over 500°F and up to 600°F [ 260°C to 316°C] consult Hi-Temp Technical Service .

APPLICATION EQUIPMENT:

Spray application is recommended: Use conventional or airless spray and good painting practices. Typical equipment is as follows:

Product Conventional Spray Airless Spray Air Fluid Fluid Tip Pressure Minimum Fluid Tip size Pressure Pressure Line

1027 60-80 psi <40 psi 1.8 to 2.2 mm 3000 psi 1/4 " to 3/8" 417 to 521

Brush and Roll : Spray application is recommended but when spray painting is not possible, brush or roll application may be used. The coating should be applied with a suitable brush or short nap roller. Brushing and rolling only in one direction may aid in building film thickness. For more specific instructions, refer to the Hi-Temp Coatings Application Guideline titled "Guidelines for Roller and Brush Application of Hi-Temp Coatings Products."
