| | EPX01 is a two-component (A & B) zinc-rich epoxy primer. | | |
| As an excellent protective primer against corrosion used on steel surfaces where superior corrosion protection is required especially in salt weathering or severe environments. Typical uses are for structural steel, pipes, tank exteriors in paper mills and oil refineries, power plants, chemical process, waste treatment plants and in all marine steel superstructures (non immersion service).
EPX01 does not stand alone as a protective coat. It should be coated by a suitable intermediate/coat such as EPX02 Gray or EPX02 MIO in order to provide the expected protection..
| | |
| • Good adhesion on structural steel.
• Excellent resistance to corrosion, it provides excellent protection of structural steel in varied weathering environments.
• High performance on marine hulls, decks and in all marine steel superstructures with suitable topcoat.
| | |
| | • Method of Application : | Airless or conventional spray, brush or roller. | | • Mixing Ratio : | ( by volume ) 1 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 : | 24 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | S405 “known as Epoxsol” is used for thinning or cleaning. Mixing ratio with thinner depends mainly on temperature and on method of application.
For example: At 20° C airless spray or roller application will need approx 15% by volume thinner S405 (higher temperatures will reduce the thinner volume ratio).
Due to potlife limitations, clean all mixing and applying tools by thinner S405 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 : | • 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 EPX01 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Component B : | CAT 10 | | • Color : | Gray | | • Volume Solids : | 78.6% (ASTM-D2697) | | • Flexibility : | Good | | • Recommended film thickness : | 50 microns “dry” | | • Theoretical spreading rate : | 15.7 m²/L at 50 microns “dry” | | • Abrasian Resistance : | Good | | • Chemical Resistance : | Depends on topcoat. | | • Solvent Resistance : | Depends on topcoat | | • Number of Coats : | 1 | | • Specific Gravity (mixed) : | 2.3 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” : 3.6 L in metal can
Component B “drier: CAT10” : 0.9 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 Sa2½ in accordance with ISO8501-1 and achieve a 25 to 50µm profile. Remove all abrasive residues and dust from surface. Apply EPX01 immediately after surface preparation to prevent any contamination. Do not leave blasted steel uncoated over night.
| | |
| | • 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. EPX01 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.
