| | EPX05 is a multipurpose two-component (A & B) solvent free epoxy. | | |
| • As tank lining for potable water, salt water, ballast and dry bulk materials.
• Reinforced by fiberglass, EPX05 may be used for cracks and break down repair.
• EPX05 is used by casting as a high-insulation hard material, such as in electronic industries.
• As a paste “Glue” for metal-to-concrete and concrete to-concrete surfaces.
• EPX05 can be mixed with Quaril for heavy duty bases especially in oil fields.
| | |
| • Suitable for use on both steel and concrete surfaces.
• Excellent abrasion resistance.
• Excellent barrier properties.
• Adheres to a variety of substrates such as steel, aluminum, stainless steel, and concrete.
• 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. (A separate leaflet CHR01 is available).

| | • Method of Application : | Airless spray, brush or roller | | • Mixing Ratio : | (by volume)
1.5 to 1 (A to B). | | • Mixing : | The individual components of EPX05 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 : | 2 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | Do not thin. Due to potlife limitations, clean 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 : | 1- 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 insure good adhesion.
2- Coated surfaces by EPX05 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured. |
| | |
| | • Component B : | CAT30 “for food and potable water contact” or CAT20 “for higher chemical resistance” | | • Color : | Transparent (brownish after mixing with CAT20) | | • Gloss : | Hi-gloss (ASTM-D523) | | • Volume Solids : | 100 % (ASTM-D2697) | | • Flexibility : | Good | | • Recommended film thickness : | 500 microns “dry” | | • Theoretical spreading rate : | 4 m²/L at 250 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Excellent (with CAT20). Very good (with CAT30) (A separate leaflet CHR01 is available) | | • Solvent Resistance : | Very good (with CAT20). Good (with CAT30) (A separate leaflet CHR01 is available) | | • Number of Coats : | 2 | | • Specific Gravity (mixed) : | 1.14 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” 1.350 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 50-100µm 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 EPX05 as soon as possible 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 EPX05 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 or EPX01 epoxy zinc rich primer). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX05 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 EPX05. New concrete must be cured at least 28 days at 21?C and 50% RH, or equivalent time. | | |
| | • Dry to Touch : | 1½ hours (ASTM-D1640). | | • Dry to Handle : | 24 hours “minimum recoat time”. 2 days “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. |
| | |
| 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 contac | |
