| | EPX13 is a two-component (A & B) high solid epoxy. | | |
| | Used directly on metal substrates or on well prepared concrete surfaces to provide a protective coat that is resistant to abrasion, corrosion, water, and some chemicals; It is highly flexible, withstanding therefore low temperatures. Typical uses are for machinery, medical laboratory instruments, electrical equipments, metal structures, industrial and laboratory walls, chemical industries, paper and cardboard factories, laundries and tanning industries, power plants, food industries, bakeries…etc. | | |
| • Excellent adhesion to metal, does not require any primer (when cleaning is used).
• Excellent flexibility, suitable for use in areas exposed to low temperatures such as in cooling rooms that reach temperatures down to -40°C.
• Excellent corrosion and weathering resistance.
• High abrasion, wear and impact resistance.
• Easy and low cost maintenance.
• 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).
• Temperature resistance up to 120°C (non-immersion service).
| | |
| | • Method of Application : | Airless spray, brush or roller. | | • Mixing Ratio : | (by volume) : 3 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 : | 2 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 up to 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 surface by EPX13 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | |
| | • Color : | Available in major industrial colors using color mixing instrument Azmix. | | • Gloss : | Gloss (ASTM D-523). | | • Volume Solids : | 60 % (ASTM-D2697). | | • Flexibility : | Excellent. | | • Recommended film thickness : | 150-350 microns “dry” | | • Theoretical spreading rate : | 4 m²/L at 150 microns “dry”. | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • 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) : | 1.2 kg/L (ASTM-D1475). | | • Packaging : | Component A “base” : 2.7 L in metal can or 10.8 L in metal drum.
Component B “drier: CAT40” : 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. Abrasive blast to Sa2½ in accordance with ISO8501-1 and achieve a 50-100 microns profile. Remove all abrasive residues and dust from surface. Apply EPX13 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 EPX13 is not taking action immediately after blasting.
CONCRETE:
Old 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 EPX16.
New concrete:
a- EPX27 primer is used after 6 to 24 hours of concrete application.
b- EPX17 primer is applied when concrete is cured for at least 14 days at 21?C and 70% RH.
c- EPX13 is applied directly when concrete is cured at least 28 days at 21°C and 50% RH.
Note: The primer should be left to achieve a dry to touch condition before applying EPX13. A second coat of primer may be required if the substrate is excessively porous. Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX13 is applied.
| | |
| | • Dry to Touch : | 1 hour (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. EPX13 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.
