Product Description

Hi-Temp 1027 is used to provide protection of insulated austenitic stainless steel against chloride induced external stress corrosion cracking. The coating is a high solid, high build system with a VOC content of 3.5 lbs./gal. It is able to do so while being exposed to severe thermal cyclic conditions to 1200° (649°) and/or boiling water. It aids in preventing chlorides: 1) in the atmosphere, 2) in the by-products of process operations, and 3) which may be incorporated in the insulation, from coming in contact with the stainless steel. The coating is formulated to contain a minimum of chlorides, sulfides, and halides, which may induce stress cracking. Hi-Temp 1027 has been tested and approved by an independent laboratory for low leachable chloride content.

Surface Preparation Stainless Steel

1. Remove all grease, oil, dirt, drawing and cutting com- pounds or other foreign matter using the SSPC-SP 1 "Solvent Cleaning" method.

2. IMPORTANT! DO NOT USE CHLORINATED SOLVENTS ON STAINLESS STEEL SURFACES.

3. For small areas, wipe solvent with HTC #5 Thinner, a chloride free solvent following proper precautions.

4. For large surface areas, steam clean with an alkaline detergent, followed by a steam or fresh water wash to remove detrimental residue.

Application Instructions*

Surface temperature must be a minimum of 5°F (3°C), above the dew point. Do not apply to steel temperatures below 50°F (10°C).

* Do not exceed maximum dry film thickness recommendations.

Maximum Dry Film Thickness: 15.0-18.0 mils. (375-450 microns)
(applied in three coats at 5-6 mils. per coat)

Application Instructions to Hot Steel

1. IMPORTANT! It is essential to apply thin coats of the Hi-Temp 1027 during an application to hot steel. This aids in allowing the solvent to escape the coating without leaving pinholes behind. This application is similar to mist coating.

2. Flush equipment with Hi-Temp #5 Thinner before using equipment.

3. Hi-Temp 1027 is normally not thinned. If the situation warrants thinning, use only Hi-Temp #5 Thinner.

4. Hi-Temp #5 Thinner is specifically formulated for Hi-Temp 1027. It is a slow evaporating solvent allowing for good film integrity as the coating is being applied to hot operating equipment.

5. WARNING! Do not thin Hi-Temp 1027 with any other solvent. A fire hazard could occur if using a different solvent system. Dry spray and poor film characteristics may occur as well.

6. Do not apply a heavy coat to a hot surface or blistering will occur. If this happens, immediately take a brush, (use wood-handled brushes with China bristles only. Do not use brush with synthetic bristles), and brush out the blister before it sets.

Equipment

Conventional or airless spray is recommended. For conventional spray use a DeVilbiss MBC-510, (or equal), gun with an "E" fluid tip and 704 air cap (or equal). For airless spray use a Graco 205-591, 208-663, (or equal), gun with fluid tip of 163-610, 163-315 and a Graco Bulldog Pump at 30:1.
Adjust pressure as needed. Hold gun 10"-12" from the surface at right angles. Lap each pass 50%. When brushing and rolling, use only quality brushes and rollers.

Mixing

Use mechanical agitation for mixing and during application. Mix materials until uniform in consistency.

Thinning

Thinning is not normally needed. If a condition warrants thinning, thin only with Hi-Temp #5 Thinner. Thin according to local air regulations.

Clean-up

Use Hi-Temp #5 Thinner.
