| | EPX66 is a three-component solvent free epoxy coating consisting of base (A), hardener (B) and quartz filler (C). | | |
| - Used to increase the compression strength of flooring requiring high resistance to heavy loads.
- Considered to be a part of epoxy floor protection system as it is applied on prepared cement floors by a suitable primer and could be topsealed by EPX06 finish.
- The epoxy flooring system composed of epoxy primer, EPX66, and EPX06 finish is considered to be ideal for use on cement floors in all installations where high resistance to heavy loads and heavy traffic of vehicles and forklifts on plant floors is required. Typical uses are in oil and chemical industies, food factories, stores, industrial kitchens, galleries, workshops, showrooms, etc...

| • Can be applied in thicknesses ranging from 1 to 4 cm by changing the size of filler “Comp.C” that can be based on Quaril for low thicknesses and on small stones up to 4 cm diameter for high thicknesses.
• High durability, resists heavy loads and high pressures.
• Easy to apply.
• Provides higher abrasion resistance than asphaltic floors.
• Easy and low cost maintenance.
• Provides when topsealed by EPX06 finish a self leveling barrier coat with attractive colors that is easy to clean and resistant to bacterial growth, water, salt solutions, detergents, oil, grease and oil derivatives.

| | • Method of Application : | Steel trowel | | • Mixing Ratio : | 1.7 to 0.9 L (A to B); the required quantity of clean, dry and dust free filler or special stones (component C) will be added according to the filler or stone diameter that will fit with the flooring thickness to be applied. Pretest a small amount of filler or stones to determine the required weight to mix to A&B components having, after mixing, 2.3L volume until achieving the viscosity that the mixture still be able to be applied on the ground. | | • Mixing : | The individual components (A and B) of EPX66 should be thoroughly stirred. Then component B “drier” should be poured into component A “base” container and mixed thoroughly using a slow speed mixer for at least 3 minutes to achieve uniform consistency; “DO NOT USE HIGH SPEED MIXER”. And finally add the filler (component C) slowly to the mixed base and drier (A&B mixed) and mix slowly for at least 3 minutes untill the mixture components are thouroughly blended. Never mix more material than can be used within potlife. Material which has begun to set must be discarded. | | • Pot life : | 30 minutes (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | Do not thin. Due to Potlife limitations, clean all mixing and applying tools by thinner S405 “known as Epoxsol” immediately after application is completed. | | • Note : | • The reaction between the epoxy components 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 EPX66 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Component B : | | | • Color : | Translucent. | | • Gloss : | flat (ASTM-D523) | | • Volume Solids : | 100 %. (ASTM-D2697) | | • Flexibility : | | | • Recommended film thickness : | 1-4 cm “dry” | | • Theoretical spreading rate : | 0.1 m²/L at 1cm “dry” | | • Water resistance : | Good | | • Abrasian Resistance : | Good | | • Chemical Resistance : | Good (A separate leaflet CHR01 is available) | | • Solvent Resistance : | Good (A separate leaflet CHR01 is available) | | • Number of Coats : | 1 | | • Specific Gravity (mixed) : | 1.94 kg/L (ASTM C97) | | • Packaging : | Component A “base” : 1.7 L in metal can
Component B “drier:CAT40” : 0.6 in metal can
Component C “special filler” : 8 kg “diameter: 0.5 to 1 mm approx.” or 16 kg “diameter: 3 to 6 mm” (dry and dust free), or according to needs with different diameter ranges.
Mixing of components A, B, and C will provide approximately 5.6 L of material that can cover a floor surface of at least 0.55 m² at a thickness of 1cm.

| Well-prepared-surface is an essential condition of coating success. In general, surface must be clean and free of all contaminants prior to coating.
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, then prime the substrate by EPX17 or EPX16 before applying EPX66.
New concrete:
a- EPX27 primer should be applied 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- EPX16 is applied when concrete is cured at least 28 days at 21°C and 50% RH.
Then apply EPX66 in the required thickness (that can be determined through the diameter of filler “Comp.C”) before the primer has achieved the dry to touch condition. EPX66 is applied by scrapper than laid by a special cylindar to level the substrate. The dry surface of EPX66 can be topcoated with EPX06 (self leveling floor coating used as a sealer/coat) if higher degrees of cleanliness and chemical resistance are required.
Note: Floor coating over concrete surfaces may require in some cases an expansion joint. Expansion joint materials can be applied above those of the concrete. Coal tar polyurethane joint sealant (JS) or other elastomeric sealants can be used for the purpose.

| | • Dry to Touch : | 1 hour (ASTM-D1640). | | • Dry to Handle : | 6 hours (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.
• 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.
