Product Description

Hi-Temp 1027 is a single component coating specifically formulated to protect cryogenic equipment. It is able to withstand severe thermal cycling from -300°F (-185°C) to 1000°F (538°C). Hi-Temp 1027 is ideal for cryogenic equipment that must also be protected against chloride induced external stress corrosion cracking of insulated austenitic stainless steel. 1027 is an ambient temperature cure system that does not require a heat cure. The coating is a high solid system with a VOC content of 3.5 lb./gal. 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.

Hi-Temp 1027 CUI, 1027 Stainless, 1027 Cryogenic, 1027 DTR and 1027 Primer are all the same product. All are delivered with the same label - Hi-Temp 1027.

Surface Preparation Stainless Steel

1. Remove all chlorides, grease, oil, dirt, drawing and cutting compounds 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).

All the following application instructions are based upon spraying the Hi-Temp 1027. For all brush and roll applications please contact HTC technical service.

*Do not exceed maximum dry film thickness recommendations.

Systems 1): Ambient Steel Application Stainless Steel

Resistance from -300°F (-185°C) to 1000°F (538°C)

Equipment

Conventional or airless spray is recommended. For conventional spray use a DeVilbiss MBC-510 (or equal) gun with an “E” fluid tip and a 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 contact HTC technical service for specific recommendations.

Mixing

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

Thinning

Thinning is not normally needed, however if a condition warrants thinning, thin only with Hi-Temp #10 Thinner. Thin according to local air regulations.

Clean-up

Use Hi-Temp #10 Thinner
