HBE-HT is a state-of-the-art surface coating designed to solve specific industry problems by combining the unique features of epoxy and proprietary cure technologies. HBE-HT is a 100% solids, two-component epoxy coating system which has been specifically designed as a protective coating for pipelines operating at elevated temperatures. This coating is available in brush and spray grade formats.

Typical Uses: Protective coating for pipelines in buried or immersed applications. Used as a direct­to-metal corrosion resistant coating and as a rehab coating on steel pipelines and at girth welds. Also used as touchup material for mainline coatings. Excellent coating for pipeline valves, fittings, and bends.

Features & Benefits

• Surface prep direct-to-steel:  Remove all visible deposits of oil, grease and other contaminants by solvent washing in accordance with SSPC SP1. Abrasive blast surface to Near-White (SSPC-SP10; NACE 2; Sa2½) or better, with a 2-4 mil blast profile.
    
• Surface prep on cured pipe coating:  Remove gloss on surface by light abrasive blasting or power tool. All surfaces to be coated must be completely dry, free of moisture, soil, dust and grit at the time the coating is applied. All weld splatter must be removed from the surface and rough welds must be ground smooth prior to coating.
    
• Clean-up:  Use xylene, MEK, or mixture.
    
• Storage:  Products must be shipped and stored at temperatures between 5°C (40°F) and 40°C (105°F). DO NOT FREEZE. Shelf life of 12 months when stored as specified.
    
• Safety: Material Safety Data Sheet and product labels contain detailed health, hygiene and safety information. This coating is intended for industrial use by properly trained professional applicators. Do not apply without adequate air exchange and ventilation in enclosed areas. Use fresh air respirator in confined areas. Wear protective clothing when spraying the coating. Breathing fumes or contact with skin can cause respiratory and other allergic reactions in some people.

• HBE-HT must be applied to clean dry surface only.
• Ambient conditions for successful application include: relative humidity less than 85%; and the substrate temperature greater than 3°C (5°F) above the dew point.
• The acceptable substrate temperature range for application of HBE-HT is 10°C (50°F) to 100°C (212°F). Applying onto warm substrate greater than 38°C (100°F) enhances coating adhesion.
• Formulated to mixing ratio of 3 parts Base to one part Cure by volume.
• If additional coats are required, they shall be applied while the preceding coat is still tacky (no tie coat needed). The maximum over-coating interval shall not exceed two (2) hours at 25°C (77°F) without roughening the surface. If recoating interval has been exceeded, surface must be blast roughened prior to application of topcoat.
• A minimum of four (4) hours curing above 20°C (68°F) is required prior to handling. Handling time maybe longer at lower temperatures.

Brush Grade:

• Apply thoroughly mixed HBE-HT Brush Grade by brush, roller or trowel. When coating pipe, remove application tools on the upstroke to prevent pulling material down and off the pipe bottom.

Spray Grade:

• HBE-HT Spray Grade shall be applied to the specified Dry Film Thickness (DFT) in a single application using a 3:1 mix-ratio Graco Hydra-Cat two-component spray equipment or approved equal.
• Pot-life of mixed components in spray hose is less than 1 minute.
• Detailed application instructions and technical support are available from Canusa.
