| | EPX105 GF is a two-component (A & B) high solids glass flake epoxy. | | |
| | High-performance, high-density glass flake-filled epoxy coating used mainly for protection of concrete and metals in aggressive service. EPX105 GF contains glass flake reinforcement and provides a tough, chemical resistant, flexible coating that is ideally suited for aggressive water service (salt and brackish). EPX105 GF is suited for acid and caustic service, and is excellent in water environments. Typical uses are in all marine constructions (super and substructures, splash and tidal zones), oil plants, oil refineries and storage plants, power plants, chemical process, etc.... | | |
| • Suitable to be applied directly on both steel and concrete surfaces or over a suitable primer.
• High build, suitable to be applied to a thickness of 750 ?m in a single coat.
• Excellent abrasion and impact resistance.
• High degree of moisture impermeabilty.
• Excellent resistance to corrosion, cavitation and erosion.
• Suitable for immersion in salt (sea) and brackish water.
• Suitable to be topcoated with wide range of topcoats for appearance or extended weatherability.
• 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 or conventional spray. | | • Mixing Ratio : | (by volume)
3.7 to 3.15 (A to B). | | • Mixing : | The individual components of EPX105 GF 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 : | 45 minutes, higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | S405 “known as Epoxsol” is used for thinning and cleaning. Due to potlife limitations, clean clean all mixing equipment and application tools by thinner 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 EPX105 GF should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Component B : | CAT32 (for food and potable water contact), CAT22 (for high chemical resistance). | | • Color : | Against order for CAT32, dark colors for CAT22. | | • Gloss : | Flat (ASTM-D523) | | • Volume Solids : | 91.9 % (ASTM-D2697) | | • Flexibility : | Excellent | | • Recommended film thickness : | 250-1000 microns “dry”, thickness of 1000 microns should be applied in very corrosive environments. | | • Theoretical spreading rate : | 3.7 m²/L at 250 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Excellent (CAT22), Very good (CAT32) "a separate leaflet CHR01 is available" | | • Solvent Resistance : | Very good (CAT22), good (CAT32) "a separate leaflet CHR01 is available" | | • Number of Coats : | 1-2 | | • Specific Gravity (mixed) : | 1.508 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” 3.7 L in US Gallon
Component B “drier” 3.15 L in US Gallon |

| 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.
EPX105 GF is suitable to be applied directly on steel surfaces 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 EPX105 GF is not taking action immediately after blasting.
Priming (where high resistance to corrosion is required): Prepare surface in accordance with application instructions for the suitable primer being used (WP or EPX02 white). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX105 GF 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 EPX105 GF. New concrete must be cured at least 28 days at 21?C and 50% RH, or equivalent time.
Priming (if required): Prepare surface in accordance with application instructions for the suitable primer being used (EPX02 gray). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX105 GF is applied.
Note: After EPX105 GF is applied, the coating surface should be inspected for the presence of surface roughness, air bubbles or any foreign matter. A final finishing coat is applied, if necessary.

| | • 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. |
| | |
| • Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight.
• Shelf life is one year 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.
