|
| | EPX 48 is a two-component high-solid epoxy coating specially designed for lining tanks containing hot water and aqueous solutions up to 120°C.
| | |
| A high-performance, anti-corrosive lining for concrete, galvanized, mild steel and stainless-steel tanks, vessels and pipes containing hot water and aqueous solutions up to 120°C.
Used as a protective anti-corrosive coating on surfaces exposed to dry heat up to 150°C. | | |
| • Withstands continuous immersion at temperatures up to 120°C.
• Withstand dry heat at temperatures up to 150°C.
• Provides long term protection of hot water tanks and condensate return tanks.
• Excellent adhesion and corrosion resistance when applied to abrasive blast cleaned steel.
| | |
| | • Method of Application : | Airless spray, brush or roll | | • Mixing Ratio : | By volume: 3.6 to 0.7 (A to B) | | • Mixing : | The individual components of EPX48 should be thoroughly stirred before the two are mixed together. Combine components (A & B) in supplied proportions and mix thoroughly using a slow speed mixer for at least 3 minutes to achieve uniform consistency; “DO NOT USE HIGH SPEED MIXER”. Never mix more material than can be used within potlife. Material that has begun to set must be discarded. | | • Pot life : | At 20°C: 30 minutes (higher temperatures significantly reduce pot life). | | • Cleaner : | S405 “known as Epoxsol” | | • Thinner / Cleaner : | for most applications, no thinner is required. If thinning is necessary a minimal amount of S405 (also known as Epoxsol) can be used. |
| | |
| | • Component B : | Cat23 | | • Color : | Grey | | • Gloss : | Semi gloss | | • Volume Solids : | 83.4% | | • Flexibility : | Very good | | • Temperature Resistance : | Dry continuous – 150°C
Immersion continuous – 120°C | | • Recommended film thickness : | 300 micron dry | | • Theoretical spreading rate : | 2.8 m²/ Liter at 300 microns dry thickness | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Very good | | • Solvent Resistance : | Good | | • Number of Coats : | 2 | | • Specific Gravity (mixed) : | 1.55 kg/Litter | | • Packaging : | Component A: 3.6 liter in metal can
Component B: 0.7 liter in metal can |

| Surface Preparation
Proper surface preparation is essential to ensure coating success, performance, and longevity. In general, all surfaces must be clean, dry, undamaged, and free of contaminants prior to application.
STEEL
? Non-immersed surfaces: Abrasive blast to Sa2 in accordance with ISO 8501-1, achieving a surface profile of 50–100 µm.
?Immersed surfaces: Abrasive blast to Sa2½ (near-white metal finish) as per ISO 8501-1, with a surface profile of 50–100 µm.
Aged or previously coated steel: Abrasive blast to Sa3 according to ISO 8501-1, ensuring a surface profile of 50–100 µm.
Additional Instructions :
• Thoroughly remove all abrasive residues and dust from the prepared surface.
• Eliminate oil, grease, wax, and similar contaminants using S405 thinner (Epoxsol).
•Apply the coating system (EPX43) as soon as possible following surface preparation to prevent recontamination. Blasted steel must not be left exposed overnight.
•If immediate application of EPX48 is not feasible, a thin layer of EPX02 primer is strongly recommended as a temporary protective coating.
• Prior to the application of EPX48 over EPX02, ensure the primed surface is clean, completely dry, and free from oil, grease, or any other contaminants.
CONCRETE
?New concrete: Must be cured for at least 28 days at 21°C and 50% RH, or for an equivalent duration based on temperature and humidity.
EPX17 primer may be applied once the concrete has cured for at least 14 days at 21°C and 70% RH.
?Old concrete: Remove surface irregularities such as fins and protrusions by stoning, sanding, or grinding.
Abrasive blasting is the most effective method to remove previous coatings, form oils, laitance, and other foreign matter.
• Fill small holes and voids with STOP200 before applying EPX48.
• For highly porous concrete or poorly ventilated areas where solvent vapors are a concern, EPX17 is recommended as the primer.
If the surface has low absorption, EPX02 is a more suitable choice.
| | |
| | • Dry to Touch : | 4 hours (ASTM-D1640). | | • Dry to Handle : | 8 hours “minimum recoat time”, 24 hours “maximum recoat time” (ASTM-D1640). | | • Fully Cured : | 7 days. | | • Note : | Drying times can be affected by many factors such as temperature, ventilation and coat thickness. Higher temperatures will shorten the drying times. |
| | |
| • Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight. EPX48 is considered under flammable materials.
• Shelf life is one year from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
• Well ventilated conditions should be provided during application.
• Do not breathe or inhale mist.
• Wear air-mask and avoid skin or eye contact.
