EPOLOCK 6600H
Product Properties
- Exceptional Thermal Resistance: Designed for continuous service in immersion conditions up to 150°C and intermittent dry heat exposure up to 280°C. It is fully resistant to steam cleaning and rapid depressurization processes.
- Extensive Chemical Resistance: Unparalleled resistance to a wide range of aggressive chemicals, including 98% sulfuric acid, 37% hydrochloric acid, concentrated alkalis, and various hydrocarbon solvents.
- Specialized Performance in Sour Gas Service: Exceptional resistance to amine solutions including DEA, MDEA, MEA, DGA, and H₂S and CO₂-rich regenerating amines, even at high operating temperatures.
- Excellent Protection Against Under-Insulation Corrosion (CUI): This system is a proven solution for combating one of the most costly types of corrosion in process industries.
- Exceptional Adhesion: Features a very high bonding strength to a wide range of aggressive metallic substrates (carbon steel, stainless steel) and composites, eliminating the need for primers in many applications (Self-Priming).
- Easy Application & Room Temperature Cure: This coating is easily applied with a brush or scraper, and does not require complex thermal equipment for full curing, significantly reducing costs and repair times.
- High Wear & Mechanical Resistance: The high hardness and strength of the final surface increases equipment lifespan in applications exposed to wear from fluid flow containing solid particles.”
Description
Descriptions EPOLOCK 6600H is an ideal solution for both OEM equipment construction and maintenance in the following industries:
Oil, Gas & Petrochemical Industries:
- Internal lining of process tanks, oil/gas/water separators, and high-pressure hydrocarbon tanks.
- Protection of sour gas units including amine absorption towers, regenerators, and amine storage tanks.
- Lining of heat exchangers, condensers, distillation columns, and evaporators.
- Repair and coating of connections, elbows, and pumps exposed to erosion-corrosion. Mineral & Material Processing Industries:
- Protection of equipment exposed to severe wear and acidic chemicals. Power Plants:
- Internal lining of condensate extraction pumps, return water tanks, and calenders. General Industrial Applications:
- Lining of autoclaves, scrubbers, and chemical reactors. Repair coating for girth welds in pipeline systems with FBE (Fusion-Bonded) coating.
Chemical Resistance: After full curing, EPOLOCK 6600H provides excellent resistance to long-term immersion in the following materials:
- Mineral Acids: Sulfuric acid (up to 98%), hydrochloric acid (up to 37%), nitric acid (up to 50%).
- Amine Solutions: Various industrial amines (DEA, MDEA, MEA, DGA, ADIP) and spent amines.
- Alkaline Solutions: Sodium hydroxide (50 to 75 percent).
- Organic Acids: Glacial acetic acid (100%).
- Hydrocarbons & Solvents: Crude oil, gasoline, xylene, toluene, and MEK.
- Acid Gases: Hydrogen sulfide (H₂S) and carbon dioxide (CO₂).
- Industrial Oils: Mineral oils and lubricants.
- Testing: After 3 days immersion in a rich amine solution at 120°C, no visible changes were observed in terms of gloss, color change, degradation, swelling, rubber-like adhesion, fine surface cracking, blistering, fracture, or solubility. The weight increase of the samples was less than 1%, and no decrease in properties was observed.

EPOLOCK 6600H is a two-part hybrid, solvent-free coating designed for long-term protection against erosion-corrosion and continuous immersion. It creates a hard, glossy, and adhesive surface at room temperature, acting as a self-priming coating and eliminating the need for primers in many applications. This system offers high thermal and thermal-dry resistance, wide chemical resistance (including amines, acids, and hydrocarbons), and excellent performance in sour gas services, oil, gas, refining, and power plant applications. It is suitable for lining tanks, heat exchangers, pumps, valves, and structural repairs with long service lives and reduced maintenance costs.
