| | EPX02 is a two-component (A &B) High-build epoxy polyamide primer and intermediate coat. | | |
| A general purpose epoxy primer used as a barrier primer on dry concrete surfaces, also suitable
to be used as a primer on metal surfaces and in automotive coating systems. Typical uses are in
household and industrial structures, chemical plants, power plants and oil production plants. Also
used as an intermediate over EPX01-40 in all places where outstanding protection against
corrosion is required such as marine steel superstructures (non- immersion service). | | |
| • Excellent adhesion.
• Good corrosion resistance.
• Excellent barrier properties.
• Suitable for a variety of substrates.
• Intermediate over EPX01-40.
• Can be coated with a wide range of topcoats (epoxy, polyurethane, alkyd, latex).
• With suitable topcoat, EPX02 can be used for immersion or non-immersion service.
• Resists continuous temperature service up to 140°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 pot life. Material that has
begun to set must be discarded. | | • Pot life : | (20°C) 24 hours (higher temperatures will shorten the pot life 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 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; The higher the temperature the
less the needed dilution. Due to pot life limitations, 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) cannot 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 should not be exposed to water, chemicals, or mechanical stresses
before it is fully cured. |

| 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, and wax …etc. from the surface to be coated by thinner S405.
Preferably, blast to Sa2½ in accordance with ISO8501-1 and achieve a 50 ?m profile.
Remove all abrasive residues and dust from surface. Apply EPX02 immediately after surface
preparation to prevent any contamination. Do not leave blasted steel uncoated overnight.
EPX01-40 coat is highly recommended directly on blasted metal for further protection, then
apply the intermediate EPX02 coat.
DRY 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. New concrete must be
cured at least 28 days at 21°C and 50% RH, or equivalent time prior to applying EPX02.
| | |
| | • Dry to Touch : | 1 hour (ASTM-D1640) | | • Dry to Handle : | 10 hours “minimum recoat time”, 24 hours “maximum recoat time” (ASTMD1640). | | • 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 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.
