| | EPX45 is a two-component epoxy coating (A, B) with high solid content. | | |
| | It is used for lining the inside of concrete and metal tanks and as a protective coating in areas exposed to wear and corrosion. It is ideal for lining and coating water pipelines, gates, and other fittings used in areas submerged in water contaminated with acidic and alkaline solutions, petroleum derivatives, and oils. | | |
| • Excellent wear resistance.
• Excellent adhesion to metal and concrete surfaces.
• Low volatile organic compounds (VOC) content.
• Can be applied in two coats without the need for a primer or final coat when surfaces are prepared by blasting.
• Easy and economical maintenance due to its smooth surface and high resistance to dust accumulation.
• Excellent resistance to water, seawater, wastewater, saline solutions, acidic saline solutions like sulfate and chloride salts, alkaline solutions like sodium and calcium salts, detergents, petroleum, aliphatic, mineral oils, and greases.
• Excellent resistance to continuous thermal fluctuations between 10-60°C (in submerged conditions) and temporary resistance to temperatures up to 85°C.

| | • Method of Application : | Airless spray, brush, or roller. | | • Mixing Ratio : | (By volume) 3.6:0.9 (A to B). | | • Mixing : | Before mixing, each component of EPX45 should be stirred separately. Then, the two components (A, B) should be mixed in the correct ratios using a slow mechanical mixer (exclusively) for at least three minutes to achieve complete homogeneity (the use of a fast mechanical mixer is prohibited). Do not mix more material than can be used within the pot life. If signs of reaction such as increased viscosity and clumping appear before use, the mixture should be discarded and not used. | | • Pot life : | At 20°C: 30 minutes (higher temperatures significantly reduce pot life). | | • Thinner / Cleaner : | Due to the limited pot life after mixing, all mixing and application tools should be cleaned immediately after use with thinner S405. | | • Note : | If another coat is applied, the drying time (maximum and minimum limits for applying another coat) must be observed. Any delay in applying interval coats may request sanding the surface of the previous coat to insure good adhesion. The reaction of the epoxy components (A, B) cannot proceed correctly unless the temperature remains above 10°C for the mixture and the surfaces to be coated until the reaction is complete. The surface temperature should be at least 3°C above the dew point to avoid vapor condensation during application. EPX45-coated surfaces should not be exposed to water, chemicals, or mechanical stresses before it is fully cured. |

| Well-prepared-surfaces is an essential condition of coating successfulness. In general, surface must be clean, dry, undamaged and free of all contaminants prior to coating.
STEEL:
• Non-submerged Surfaces: Use blasting (e.g., sandblasting) to Sa2½ grade according to ISO 8501-1 to remove 50-100 microns, then remove dust or any blasting residues from the surface.
• Submerged Surfaces: Use blasting to Sa2½ grade according to ISO 8501-1 to achieve a near-white metal finish, removing 50-100 microns. If the metal is old, scrape to Sa3 grade according to ISO 8501-1, then remove dust or any scraping residues from the surface.
• EPX45 should be applied immediately after surface preparation to prevent loss of surface readiness for coating and should not be left uncoated until the next day. During application, ensure the substrate is clean, dry, and free from oils, greases, and any residues or contaminants.
CONCRETE:
• Clean the surface of any protrusions or adhering materials by grinding, sandblasting, or using grinding stones.
New concrete: allow the concrete surfaces to cure for 28 days at 21°C with a relative humidity of 50% or the equivalent time.
Old concrete: sandblasting is the best way to remove previous coatings, formed oils, cement slurry residues (grout), and foreign bodies. Then, fill cracks or small gaps with Stop 200 before applying EPX45.
If sandblasting is not possible, an EPX02 ZP primer layer can be applied after cleaning according to EPX02 ZP application conditions on metal surfaces, and an EPX17 layer can be applied on concrete surfaces following EPX17 applying conditions. | | |
| | • Dry to Touch : | 2 hours (ASTM-D1640). | | • Dry to Handle : | 24 hours (minimum time for another coat), 2 days (maximum time for another coat) (ASTM-D1640). | | • Fully Cured : | Seven days. | | • Note : | Drying time is affected by several factors such as temperature, ventilation, and coating thickness; higher temperatures significantly reduce drying time. |
| | |
| Epoxy, especially the curing agent (component B), should be stored in a cool, well-ventilated place, away from heat and direct sunlight. EPX45 is classified as flammable.
• Shelf Life: One year from the date of packing, provided it is stored in its original sealed containers at temperatures between 10 - 40°C.
• Warning:
• The application area must be well-ventilated during application.
• Avoid inhaling fumes.
• Use a mask and avoid contact with skin or eyes. | |
