Highland International 827-HB

Highland International 827-HB is a unique high-build single package inert multipolymeric matrix coating designed to provide heat stability & withstand severe cyclic conditions up to 1200˚F. It is an excellent choice for coating under insulation (CUI), stacks, chemical plant components, refineries and other areas that require corrosion protection and see elevated temperatures up to 1200˚F. It is specifically formulated to allow application to marginally prepared surfaces, and may even be applied over tightly adhered rust. 827-HB shows superior thermal shock resistance even when applied in excess of 16 mils TDFT, providing the best characteristics of a high temperature coating in a Dry-Fall “Spray Safe” formula that eliminates overspray worries and meets SS-4, SS-5, CS-6 and CS-8 of NACE SP0198-10.

Surface Preparation

All surfaces should be clean, dry and free of all foreign contaminants.
A SSPC-SP1 Solvent Cleaning with Highland 901 Cleaning Solvent is recommended before blasting or other cleaning method.

Carbon Steel:
Best: A SSPC-SP 10 Near White Metal Blast to achieve a low blast profile of 1.5-3.0 mils is recommended (especially for CUI services).
Good: A SSPC-SP6 Commercial Blast will provide good results in most situations.
Acceptable: While abrasive blast cleaning is preferred, when it is not an option, Hand or Power Tool Cleaning per SSPCSP2 or SSPC-SP3 may be used and will provide good results.

Galvanized Steel: Contact a Highland representative as recommendation will vary depending on substrate and exposure conditions.

Mixing & Application

Mixing: Highland 827-HB Series needs to be thoroughly mixed using mechanical agitation. It is ready to spray after proper mixing.

Reduction for Standard Spray Applications: Reduction is not required, if desired, reduce by 0% - 10% with Highland 30-E or 32-E reducer.

Reduction for Dry-Fall “Spray-Safe” Applications: Highland 827-HB Series must be reduced 10%-20% with Highland 30-E or 32-E reducer to achieve the dry-fall effect. Surface temperatures should not exceed 140˚F when using 827-HB Series in a dry-fall application.

To ensure optimal performance, apply according to recommendations below.

Typical Systems
  • CUI Services: Apply 2 coats of 827-HB Series at 6-8 mils DFT per coat to achieve 12-16 mils TDFT
  • DTM Services: Apply 1 coat of 827-HB Series at 4-8 mils DFT for mild services or 2 coats at 4-8 mils DFT per coat to achieve 8-16 mils TDFT for severe services
  • Primer/Topcoat: 827-HB Series may be used as a primer with Highland 815 Series (up to 500˚F) or 899 Series (up to 1000˚F)

Technical Details & Test Data

Performance Data

Thermal Shock, Adhesion, Salt Spray, Cryogenic and CUI test data is available for various substrate preparations.

CUI Cycle Testing
1 Cycle = 1 Week: 16 hours at 500°F/260°C, cold water quench followed by 8 hours in boiling water 212°F/100°C. Repeat for 5 days, then 2 days at 500°F/260°C followed by cold water quench.
Results (16 Cycles):

  • No cracking or blistering in the field
  • No loss of adhesion, 5A per ASTM D 3359

Thermal Shock Resistance
A set of panels prepared per Highland specifications (12 mils DFT) were subjected to 1200°F/649°C for 24 hours and immediately submerged into room temperature water. The coated panels were inspected under a microscope and checked for dulling, micro-cracks, and adhesion. The panels were then exposed to 24 hours of salt spray testing (ASTM B117) and examined for rust or any corrosion attack.
Method: ASTM D2485
Result: (30+ Cycles): Pass - no micro-cracks or blistering in the field, no corrosion present

Salt Spray:
Coatings were applied at 12-16 mils DFT respectively per manufacturer recommendations.
Panels were evaluated every 100 hours.
