HBE-95G, by Canusa-CPS
High-build epoxy coating for buried pipelines, operating up to 95°C (203°F).
HBE-95 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-95 is a 100% solids, two-component epoxy coating system which has been specifically designed as an exterior coating applied to bare steel for protection of pipe joint girth welds, valves and fittings, or as a touch-up material or rehabilitation system for mainline coatings.
Typical Uses
Protective coating for pipelines in buried or immersed applications. Used as a direct-to-metal corrosion and abrasion-resistant coating and as a rehab coating on steel pipelines and at girth welds. Also used as touch-up material for mainline coatings. Excellent coating for pipeline valves, fittings, and bends.
Features
- High Build in a single coat.
- Sets and cures over a broad temperature range
- Environmentally safe.
- 100% solids, Zero V.O.C.
- Excellent adhesion to grit blasted steel -- an ideal mainline corrosion coating for pipelines.
- Superior adhesion to Fusion Bonded Epoxy (FBE) Coatings -- ideal coating for joint protection and repair of FBE coated pipe.
- Excellent chemical & abrasion resistance.
- Outstanding resistance to cathodic disbonding up to 95°C (203°F) operating temperature.
- Easily applied with brush or roller.

Surface Preparation
- Direct-to-steel
Remove all visible deposits of oil, grease and other contaminates by solvent washing in accordance with SSPC-SP1. Abrasive blast surfaces to a Near-White (SSPC-SP 10, NACE 2, SA2 1/2) or better, with a 2-4 mil blast profile.
- 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.
Cleanup, Storage & Safety
- Clean-up
For clean-up use xylene, MEK or mixture.
- Storage
Products must be shipped and stored at temperatures between 15°C (60°F) and 40°C (105°F). DO NOT FREEZE.
- 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. See MSDS for HBE-95-BG Base and MSDS for HBE-95-BG Cure.
Mixing & Application Instructions
- For detailed application instructions please refer to HBE-95 Installation Guide.
- Materials must be allowed to warm to at least 28°C (70°F) prior to mixing.
- Pre-mix Base (more viscous component) slowly with a variable speed drill gun fitted with an appropriate mixing impeller.
- Pour pre-measured Hardener into pre-measured Base.
- At temperatures between 15°C (59°F) and 40°C (105°F). Mix for one (1) minute blend both parts to create one uniform color with no streaks. Begin mixing slowly. Caution: Mix at a speed that ensures a uniform mix, but does not create a vortex in the liquid. Slow mixer down at surface of the liquid to prevent introduction of air into the coating.
- Pot-life is approximately 15 minutes at 20°C (70°F) and shortens with increased temperatures.
- HBE-95 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-95 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 1 part Hardener 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.
- Apply thoroughly mixed HBE-95 by brush, roller or trowel. When coating pipe, remove application tools on the upstroke to prevent pulling material down and off the pipe bottom.
