| | EPX48 is a two-component epoxy coating (A, B) with high solid content. | | |
| 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 |

| Well-prepared surfaces are an essential condition of coating success. In general, the surface must be clean, dry, undamaged and free of all contaminants prior to coating.
STEEL: Remove all oil, grease, wax, etc. from the surface to be coated by thinner S405 (Epoxsol).
Non-immersed: Abrasive blast to Sa2½, in accordance with ISO 8501-1, and achieve a 50-100 microns profile. Remove all abrasive residues and dust from the surface.
Immersed: Abrasive blast to Sa2½, a near white metal finish in accordance with ISO 8501-1, and achieve a 50-100 µm profile. Old steel to Sa3 in accordance with ISO 8501-1.Remove all abrasive residues and dust from the surface.
Apply EPX48 as soon as possible after surface preparation to prevent any contamination. Do not leave blasted steel uncoated overnight. A thin coat of EPX02 primer is highly recommended if treatment with EPX48 is not taking action immediately after blasting.
Priming (for non-immersion service where high resistance to corrosion is required): Prepare surface in accordance with application instructions for the suitable primer being used (EPX02). Be sure the primer is clean, dry, and free of oil, grease, and any other contaminants when EPX48 is applied.
CONCRETE: Remove fins and other protrusions by stoning, sanding or grinding.
New concrete: Must be cured at least 28 days at 21°C and 50% RH, or equivalent time.
Old concrete: Abrasive blasting is best to remove all previous coatings, form oils, laitance and other foreign matter. Fill small holes or voids with STOP200 before applying EPX48. If the concrete surface has a high absorption, EPX17 primer is highly recommended to be applied. | | |
| | • 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.
