|
| | A primer/coat based on two-component (A&B) high build coal-tar epoxy. | | |
| Used for the isolation and protection of concrete, steel, aluminum, and wooden structures exposed to hard conditions providing protection from water, sea water, dissolved salts and impurities, .…etc. Typical uses are in marine structures, ships, power plants, cooling towers (using cold water), sewage treatment plants, buried or immersed water carrying pipes and tanks (except potable water). And also as a protective coat on asphalt or concrete garage floors and as barrier insulation that can be applied under and over concrete slabs.
Note:
For immersion service and severe exposure conditions dry film thickness should be at least 350 microns dry. This can be achieved as a two-coat application of 175 microns each.

| • Excellent resistance to water, sea-water, waste water, salt solutions, diluted acids and bases, detergents, mineral oils, and greases.
• Permanent flexibility with outstanding toughness, offers considerably more flexibility than regular epoxies.
• Excellent corrosion, impact, and abrasion resistance.
• Does not require any primer or topcoat when blasting is applied.
• Low cost, alternative to more expensive 2k coatings.
• Suitable for lining water tanks (Except potable water).
| | |
| | • Method of Application : | Airless spray 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 : | 3 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 application or roller will need approx. 15% by volume thinner S405. The higher the temperature the less the needed dilution. Due to potlife limitations, clean all mixing and applying tools by thinner S405 immediately after application is completed. | | • Curing : | | | • 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 EPX14 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Component B : | | | • Color : | Black | | • Gloss : | Flat (ASTM-D523) | | • Volume Solids : | 73.2 % (ASTM-D2697) | | • Flexibility : | Excellent | | • Recommended film thickness : | 175-350 microns “dry”. | | • Theoretical spreading rate : | 4.2 m²/L at 175 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Good | | • Solvent Resistance : | Fair | | • Number of Coats : | 1-2 | | • Specific Gravity (mixed) : | 1.264 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” : 14.4 L in metal drum or 3.6 L in metal can.
Component B “drier:CAT10” : 3.6 or 0.9 L in metal can.

| Well-prepared-surface is an essential condition of coating success. In general, surfaces 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.
• Non-immersed (old or new metal): Abrasive blast to Sa2½ in accordance with ISO8501-1 and achieve a 50-100 µm profile. Remove all abrasive residues and dust from surface. Where high corrosion resistance is required it is recommended to apply the primer (WP).
• Immersed :
- New steel: abrasive blast to Sa2½, a near white metal finish in accordance with ISO8501-1.
- Old steel, abrasive blast to Sa3 in accordance with ISO8501-1 to white metal.
Remove all abrasive residues and dust from surface, and then apply EPX14 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 EPX14 is not taking action immediately after blasting.
ALUMINUM:
Aluminum surfaces should be sanded to roughen the substrates and to remove all contaminates.
CONCRETE:
• Old concrete: Remove fins and other protrusions by stoning, sanding or grinding. Sand blasting is best to remove all previous coatings, form oils, laitance and other foreign matter. Fill holes or voids with STOP200 before applying EPX14.
• New concrete:
a- After 24 hours of concrete application: Prime with EPX27 then apply EPX14 after complete drying of EPX27.
b- After complete setting of concrete (i.e. 28 days at 21?C and 50% RH): Apply EPX14 directly.
Note: EPX19 can be used instead of EPX14 in closed area, on damped concrete surfaces or concrete surfaces exposed high relative humidity.
WOOD:
Wooden surfaces require the removal of all coatings by rough sanding.

| | • 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. |
| | |
| • Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight. EPX14 is classified as being highly flammable materials.
• 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.
