EPX07
Description
A two-component (A & B) water-based epoxy coat.
Recommended Uses
used as a protective coat for concrete surfaces to provide excellent resistance to abrasion, water, bacterial growth, and chemicals. Typical uses are in hospitals, kindergarten, schools, laboratories, operation rooms, food & beverage industries, pharmaceutical industries, and in all areas where no solvents are allowed and high degree of hygienity is required.
Features
• Excellent adhesion to concrete substrates.
• Excellent abrasion and wear resistance.
• Excellent barrier properties, provides excellent resistance to water, desinfecting solutions, salt solutions, alkalis, detergents, white spirits, aliphatics, mineral oils and fatty oils (A separate leaflet CHR01 is available).
• Improves concrete properties when coated directly on concrete surfaces.
• Easy and low-cost maintenance.
• 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, brush or roller.
• Mixing Ratio : (by volume) 4 to 1 (A to B).
• Mixing : The individual components should be thoroughly stirred before the two are mixed
• Pot life : 2 hours (higher temperatures will shorten the potlife sharply).
• Thinner / Cleaner : Water is used for thinning or cleaning. Mixing ratio with thinner depends mainly on
• 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 blasting the surface of the previous coat to insure good adhesion.

• Packaging : Component A : 3.6 L in metal can. Component B (drier CAT70) : 0.9 L in metal can.
• Weather Resistance : Excellent.
Surface Preparation
Well-prepared-surfaces is an essential condition of coating successfulness. In general, surface must be clean, undamaged and free of all contaminants prior to coating. 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 priming.
Priming: Prepare surface in accordance with application instructions for the suitable primer being used (WT05 or EPX17). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX07 is applied.

Priming: Prepare surface in accordance with application instructions for the suitable primer being used (EPX17). Be sure primer is clean, dry, and free of oil, grease and any other contaminants when EPX07 is applied.
Drying Time
• Dry to Touch : 1½ hours (ASTM-D1640).
• Dry to Handle : 36 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
• Epoxy system, in general, 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.
