| | EPX04 is a two-component (A & B) solvent free coal tar epoxy. | | |
| 1- As a protective coat from corrosion and mechanical wear used in underground and under water structures for immersed or buried fresh and salt water-carrying pipes, tanks, marine structures, ships, power plants, oil production and refining plants, cooling towers and sewage treatment plants, etc.
2- As a lining for immersion in crude oil,salt solutions, water (non-potable), salt water and waste water.
3- Fiberglass may be involved for higher protection against cracks and wearing. | | |
| 1- Over 400 microns film thickness in only one coat.
2- Single coat application, high performance protection.
3- Suitable for use over both steel and concrete surfaces.
4- Excellent corrosion and abrasion resistance.
5- Does not require any primer or topcoat when blasting is applied.
6- Excellent resistance to water, sea-water, waste water, salt solutions, acids, alkalis, detergents, white spirits, aliphatics, mineral oils, fatty oils, crude oil, fuels, and a wide range of industrial chemicals.
7- Suitable for tank lining, immersion or non-immersion service (Except potable water). | | |
| | • Method of Application : | Airless spray, brush or roller. | | • Mixing Ratio : | (by volume)
4 to 1 (A to B). | | • Mixing : | The individual components of EPX04 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 : | 3 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | Do not thin. Due to Potlife limitations, clean all mixing equipment and application tools by thinner S405 “known as Epoxsol” immediately after application is completed. | | • Curing : | 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. | | • Note : | Coated surfaces by EPX04 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured. |
| | |
| | • Component B : | CAT20 | | • Color : | Black | | • Gloss : | Gloss (ASTM-D523) | | • Volume Solids : | 100 % (ASTM-D2697) | | • Flexibility : | Excellent | | • Recommended film thickness : | 400 microns “dry” | | • Theoretical spreading rate : | 2.5 m²/L at 400 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Excellent (A separate leaflet CHR01 is available) | | • Solvent Resistance : | Very good (A separate leaflet CHR01 is available) | | • Number of Coats : | 1 | | • Specific Gravity (mixed) : | 1.45 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” 3.6 L in US Gallon
Component B “drier 0.9 L in US Quart |

| 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:
Remove all oil , grease, wax…etc from the surface to be coated by thinner S405 or S100 (recommended for removing oily dirt on non-porous substrates).
Non-immersed : Abrasive blast to Sa2½ in accordance with ISO8501-1 and achieve a 50-100 µm profile. Remove all abrasive residues and dust from surface.
Immersed: Abrasive blast to Sa2½, a near white metal finish in accordance with ISO8501-1, and achieve a 50-100 µm profile. Old steel to Sa3 in accordance with ISO8501-1. Remove all abrasive residues and dust from surface.
Apply EPX04 immediately after surface preparation to prevent any contamination. Do not leave blasted steel uncoated over night. A thin coat of wash primer “WP” is highly recommended if treatment with EPX04 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 (WP). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX04 is applied.
CONCRETE:
Remove fins and other protrusions by stoning, sanding or grinding. 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 EPX04. New concrete must be cured at least 28 days at 21?C and 50% RH, or equivalent time
For damp surfaces or in areas where high relative humidity is present use EPX19 and / or EPX09 instead of EPX04 to ensure better adhesion to the substrate. | | |
| | • Dry to Touch : | 1½ hours (ASTM-D1640). | | • Dry to Handle : | 24 hours (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. |
| | |
| 1- Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight.
2- Shelf life is one year from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
1- Well ventilated conditions should be provided during application.
2- Do not breathe or inhale mist.
3- Wear air-mask and avoid skin or eye contact. | |
