| | EPX08 is a two-component (A & B) water-based epoxy. | | |
| | EPX08 is used as a primer/sealer for concrete surfaces. Typical uses, with a suitable coating systems, are in chemical plants, textile factories, hospitals, food and beverage industries, and pharmaceutical industries …etc. | | |
| 1- Penetrates and seals concrete surfaces and improve concrete properties.
2- Can be mixed with masonry to improve its mechanical specification.
3- Excellent resistance to water, sea water, salt solutions, alkalis, detergents, white spirits, aliphatics, mineral oils and fatty oils (A separate leaflet CHR01 is available).
4- No harmful vapors and scents are present (makes it easy to use and to apply even in confined areas) | | |
| | • Method of Application : | Brush, roller or spray gun. | | • Mixing Ratio : | (by volume)
4 to 1 (A to B) | | • Mixing : | The individual components of EPX08 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 : | 1.5 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | Water is used for thinning or cleaning. Due to potlife limitations, clean all mixing and applying tools by water immediately after application is completed | | • Curing : | 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. | | • Note : | 1- 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.
2- Coated surfaces by EPX08 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured |

| | • Component B : | CAT70 | | • Color : | Colorless | | • Gloss : | Semi-gloss (ASTM-D523) | | • Volume Solids : | 58 % (ASTM-D2697) | | • Flexibility : | Very good | | • Recommended film thickness : | 40-60 microns “dry” | | • Theoretical spreading rate : | 11.6 m²/L at 50 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Very good | | • Chemical Resistance : | Good (A separate leaflet CHR01 is available) | | • Solvent Resistance : | Fair (A separate leaflet CHR01 is available) | | • Number of Coats : | 1 | | • Specific Gravity (mixed) : | 1.05 kg/L (ASTM-D1475) | | • Packaging : | Component A 3.6 L in US Gallon
Component B 0.9 L in US Quart |

| 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.
CONCRETE:
Remove fins and other protrusions by stoning, sanding or grinding.
New concrete: Must be cured at least 28 days at 21?C and 70% RH, or equivalent time.
Old concrete: 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 EPX08.
| | |
| | • Dry to Touch : | 2 hours (ASTM-D1640). | | • Dry to Handle : | 12 hours “minimum recoat time”, 24 hours “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. |
| | |
| 1- Epoxy system, in general, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight.
2- Shelf life is one year from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
1- Well ventilated conditions should be provided during application.
2- Do not breathe or inhale mist.
3- Wear air-mask and avoid skin or eye contact
