EPX18
Description
EPX18 is a two-component (A &B) high solids epoxy coating.
Recommended Uses
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.
Features
• 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.
Application Instruction
• 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.

Surface Preparation
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 EPX18 as soon as possible after surface preparation to prevent any
contamination. Do not leave blasted steel uncoated overnight.
A thin coat of Epx02primer is highly recommended if treatment with EPX18 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 Epx18 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 EPX18.
If the concrete surface has a high absorption,EPX 17 primer is highly recommended
to be applied.

Drying Time
• 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.
Storing Conditions
• 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.
