| | A two-component (A & B) epoxy primer/coat containing lamellar micaceous iron oxide (MIO). | | |
| | A general purpose epoxy primer/intermediate/finishing coat used to protect metal and dry concrete structures to give hard and highly adherent coat that is resistant to corrosion, abrasion, weathering, water, and chemicals. Also suitable to be used as a primer on metal substrates where blasting is prohibited or impossible. | | |
| • Excellent adhesion to almost all types of substrates (steel, galvanised steel, tight rusted steel, concrete, and to most aged coatings).
• Excellent corrosion, weathering, and UV resistance.
• Good abrasion and impact resistance.
• Excellent resistance to water, sea water, waste water, salt solutions, alkalis, detergents, white spirits, aliphatics, mineral oils, and fatty oils (A separate leaflet CHR01 is available).
• Can be used in systems for water immersion services..
• Can be topcoated with a wide range of finishing coats (epoxy, urethane, alkyd, latex).
• Resistant to temperatures up to 200°C "non immersion service".
| | |
| | • Method of Application : | Airless or conventional spray, brush or roller. | | • Mixing Ratio : | (by volume) : 4 to 1 (A to B). | | • Mixing : | The individual components 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 : | (20°C) : 24 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | S405 “Known as Epoxsol” is uesd for thinning or cleaning. Mixing ratio with thinner depends mainly on temperature and on method of application.
For example: At 20°C airless spray application will need no dilution.
Conventional spray will need approx 25% by volume thinner S405. Other methods of application will need approx 15% by volume thinner S405 (higher temperatures will reduce the thinner volume ratio). Due to potlife limitions, clean all mixing and applying tools by thinner S405 immediately after application is completed.
| | • 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 insure 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 EPX02 MIO should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Color : | Light Gray. | | • Gloss : | Flat (ASTM-D-D523). | | • Volume Solids : | 60.0 % (ASTM-D2697). | | • Flexibility : | Good. | | • Recommended film thickness : | 50-150 microns “dry”. | | • Theoretical spreading rate : | 12 m²/L at 50 microns "dry". | | • Water resistance : | Excellent. | | • Abrasian Resistance : | Good. | | • Chemical Resistance : | Good (A separate leaflet CHR01 is available). | | • Solvent Resistance : | Fair (A separate leaflet CHR01 is available). | | • Number of Coats : | 1-2. | | • Specific Gravity (mixed) : | 1.42 kg/L (ASTM 1475). | | • Packaging : | Component A “base” : 0.9 or 3.6 or 14.4 L in metal drum.
Component B “drier: CAT10” : 0.225 or 0.9 or 3.6 L in metal can.

| Well-prepared-surface is an essential condition of coating success. 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. Preferably, blast to Sa2 in accordance with ISO8501-1 and achieve a 50 µm profile. Remove all abrasive residues and dust from surface. Apply EPX02 MIO immediately after surface preparation to prevent any contamination. Do not leave blasted steel uncoated overnight. A thin coat of wash primer “WP” is highly recommended if treatment with EPX02 MIO is not taking action immediately after blasting. It is also recommended to apply EPX02 MIO on zinc rich primers (EPX01 or EPX01-40) for non immersion services where outstanding corrosion resistance is required.
Previously Painted Surfaces:
Remove all loose, peeling, or blistered paint, and any other surface contaminants.
CONCRETE :
Remove fins and other protrusions by stoning, sanding or grinding. Fill small holes or voids with STOP200 “refer to its technical leaflet” before applying EPX02 MIO. New concrete must be cured at least 28 days at 21°C and 50% RH, or equivalent time prior to applying EPX02 MIO. For damp concrete, it is recommended to apply EPX17 primer (Water based epoxy) prior to applying EPX02 MIO.

| | • Dry to Touch : | 1 hour (ASTM-D1640). | | • Dry to Handle : | 10 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. EPX02 MIO is classified as being highly flammable material.
• Shelf life is two years 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.
