EPX09
Description
EPX09 is a two-component (A&B) water-based coal tar epoxy.
Recommended Uses
1- As a protective coat to separate concrete foundations from the ground soil and to prevent moisture and dissolved salts to sip in, such as in bridge ground beams, swimming-pool structures and under the central heating systems …etc. Also, EPX09 is used as a protective and insulating layer to support concrete walls from moisture and dissolved salts.

2- Suitable as a barrier for the protection of underground surfaces, manholes, open or closed concrete reservoirs, sewage treatment plants, water-carrying pipes and tunnels (except potable water) …etc from waste, water, chemicals, oils, greases, and petroleum products
Features
1- Very fine and smooth surface.

2- Excellent adhesion to concrete with excellent flexibility.

3- Easy to apply even on damp concrete.

4- Suitable for water immersion service.

5- Exellent 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).

6- No harmful vapors and scents are present (makes it easy to use and to apply even in confined areas)
Application Instruction
• Method of Application : Airless spray or roller.
• Mixing Ratio : (by volume) 4 to 1 (A to B). water is added after mixing.
• Mixing : The individual components of EPX09 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 until uniform consistency is achieved; “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 : 4 hours (higher temperatures will shorten the potlife sharply).
• Thinner / Cleaner : Water 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 will need no dilution. Other method of application will need approx 15% by volume water. The higher the temperature the less the needed dilution. 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 EPX09 should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

Surface Preparation
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.Abrasive blasting is best to remove all previous coatings, form oils, laitance and other foreign matters. New concrete must be cured at least 28 days at 21°C and 70% RH or equivalent time.

Fill small holes or voids with STOP200 before applying EPX09.

Priming “if needed”: Prepare surface in accordance with application instructions for the suitable primer being used (EPX19). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX09 is applied.
Drying Time
• Dry to Touch : 2 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.
Storing Conditions
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.
