|
| | EPX18 is a two-component high-solid epoxy coating specially formulated for lining tanks containing crude oil and petroleum products such as gasoline, kerosene, diesel, and fuel oil.
| | |
| EPX 18 is a high solid epoxy coating used for lining internal steel and concrete tanks, valves and
pipes; containing crude oil and petroleum products such as gasoline/kerosene/diesel/fuel oil/etc.
| | |
| • Economical tank lining coating for crude oil and petroleum products.
• Excellent for protecting tanks from corrosion .
• Excellent abrasion resistance.
• Excellent adhesion on concrete and metal surfaces.
• Applied in two coats, does not require any primer or topcoat when
blasting is applied.
• Easy and low-cost maintenance due its smooth surface and its high dust resistance.
• Excellent resistance to crude oil and petroleum products such as
gasoline/kerosene/diesel/fuel oil/etc even at the highest temperature of 150°c. | | |
| | • Method of Application : | Airless spray, brush or roller. | | • Mixing Ratio : | (by volume) 3.5 to 0.9 (A to B). | | • Mixing : | The individual components of EPX18 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 pot life. Material that has begun to set must be discarded.
| | • Pot life : | (20° C) 30 minutes (higher temperatures will shorten the pot life sharply). | | • Cleaner : | S405 "also 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. | | • Note : | • When recoating, a special attention should be given toward drying times “minimum &maximum recoating time”. Any delay in applying interval coats may request sanding the surface of the previous coat to ensure good adhesion.
• The reaction between the epoxy and its curing agent (A &B) can not be guaranteed unless a temperature of at least 10 °C is maintained for the mixture and the substrate until complete curing. Temperature of substrate should be at least 3°C above dew point to avoid moisture condensation during application.
• Coated surfaces by EPX18 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured. |

| | • Component B : | CAT21 | | • Color : | Grey | | • Gloss : | Semi-Gloss (ASTM-D1523)
| | • Volume Solids : | 57.5 % (ASTM-D2697 | | • VOC : | 88 g/L (ASTM-D3960) | | • Flexibility : | Very good
| | • Temperature Resistance : | very Good | | • Recommended film thickness : | 500 microns “dry” | | • Theoretical spreading rate : | 1.15 m²/L at 500 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Excellent | | • Number of Coats : | 2 | | • Specific Gravity (mixed) : | 1.20 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” 3.5 L in a metal can Component B “drier” 0.9 L
in a metal can (CAT21) . |

| 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 (EPX18) as soon as possible following surface preparation to prevent recontamination. Blasted steel must not be left exposed overnight.
•If immediate application of EPX18 is not feasible, a thin layer of EPX02 primer is strongly recommended as a temporary protective coating.
• Prior to the application of EPX18 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 EPX18.
• 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. EPX18 is considered under
flammable materials.
• Shelf life is one year from the 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 an air-mask and avoid skin or eye contact. | |
