ECS-9 EPOXY COATING-GROUTING COMPOUND

ECS-9 can be mixed with sand to form a trowelling consistency paste for a trowel-down floor or for filling cracks or voids in concrete or masonry work. Alternatively it can be brushed or rolled over concrete (with damage lines/cracks ) and sand or a fine gravel (or a non-skid substrate) can be broadcast EVENLY over the epoxy.

The excess sand is later brushed off, if desired. If used as a clear coating, note that there is a slight color to ECS-9.

ECS-9 IS A TWO PART EPOXY WITH A NUMBER OF FEATURES TO RECOMMEND IT:

* BONDS WELL TO MOST METALS, WOODS AND CONCRETE PRODUCTS.

* BONDS TO DAMP CONCRETE SURFACES. ALSO CAN BE USED FOR BONDING WET CONCRETE TO CURED CONCRETE.

* IS ONE OF THE MORE ECONOMICAL UNFILLED EPOXY SYSTEMS THAT IS AVAILABLE.

* COMBINES A BALANCE OF GOOD WATER AND CHEMICAL RESISTANCE WITH EXCELLENT PHYSICAL PROPERTIES.

* LOW VISCOSITY ALLOWS FOR ADDITION OF UP TO 6-7 PARTS BY WEIGHT OF CLEAN SAND AS MIGHT BE USED FOR MAKING TROWELING COMPOUNDS AND MORTAR MIXES.

(BONDING TO PLASTICS REQUIRES A PRIMER.)

APPLICATION OF ECS-9 SURFACES SHOULD BE CLEAN, SOLID AND FREE FROM ALKALINITY. (pH of 5 to 7 approx.). SURFACES MAY BE DAMP, BUT SHOULD NOT BE WET. METALS SHOULD BE CLEANED OR BLASTED TO "BRIGHT" METAL. BEST RESULTS WILL BE OBTAINED AT SURFACE AND MATERIAL TEMPERATURES ABOVE 54 DEGREES F.

A) PREPARE THE CONCRETE: (see separate brochure).

B) MIX (2) PARTS OF PART A TO (1) PART OF PART B BY VOLUME WITH DRILL MOTOR OR PAINT STIRRER UNTIL THOROUGHLY MIXED. MIX ONLY ENOUGH MATERIALS AS TO BE ABLE TO USE WITHIN THE POT LIFE. IT IS ADVISABLE TO TRANSFER THE THE ORIGINAL MIX OF PART A/PART B TO A SECOND MIX CONTAINER AND THEN GIVE THIS A SECOND MIX - this ensures proper mixing. CAUTION! DO NOT SCRAPE SIDES OF ORIGINAL MIX CONTAINER ONTO THE FLOOR - this could be unmixed Part A or unmixed Part B and could cause non-cured wet spots on the finished floor.

THEN MIX WITH SAND OR NON-SKID AGGREGATE IF DESIRED. TYPICALLY USE 6 PARTS OF SAND TO 1 PART OF EPOXY MIX TO GET A GROUTING PASTE CONSISTENCY.

(Colored sand or aggregate can also be broadcast evenly over the epoxy while it is still wet to give a non-skid finish. Excess sand is later vacuumed away.)

C) POUR THE MIXED EPOXY ONTO THE FLOOR AREA TO BE COVERED AS SOON AS IT HAS BEEN THOROUGHLY MIXED - it gives more working time when spread in a thin layer.

REMEMBER, POT LIFE IS GREATLY REDUCED WITH INCREASED TEMPERATURE; HALF AS LONG AT 90 DEGREES F, AS AT 72 DEGREES F. LARGER MIXES ALSO HAVE MUCH SHORTER POT LIFE.

TROWEL THE EPOXY PASTE TO A SMOOTHE LEVEL COATING OF THE DESIRED THICKNESS - OR IF USING STRAIGHT EPOXY (no aggregate) SPREAD THE MIXED EPOXY LIQUIDS EVENLY TO AN EVEN COVERING USING A NOTCHED SQUEEGEE OF THE DESIRED THICKNESS RATING.

D) LEAVE THE EPOXY TO CURE FOR 8 TO 10 HOURS (@ 70 DEG. F ) , BEFORE PUTTING ON SECOND COAT (IF REQUIRED). THIS EPOXY IS SELF PRIMING, BUT A THIN, INITIAL COAT OF STRAIGHT EPOXY CAN BE USED AS A PRIME COAT-SEALER.

CLEAN-UP: TOLUENE, MEK OR BLENDED "EPOXY CLEANING SOLVENTS".

PRECAUTIONS: AVOID CONTACT WITH SKIN AND EYES. IN EVENT OF CONTACT, WASH OFF SKIN WITH SOAP AND WATER AS SOON AS POSSIBLE. WASH EYES THOROUGHLY WITH WATER AND CONSULT A PHYSICIAN. PRODUCT CONTAINS EPOXY RESINS AND ORGANIC AMINES. SEE MSDS FOR FURTHER INFORMATION.

SHELF LIFE: ONE YEAR GUARANTEED IN UNOPENED CONTAINERS. PART A MAY CRYSTALLIZE IF STORED COLD.(BUT CAN BE REMELTED BY HOLDING IN VERY HOT WATER FOR SEVERAL HOURS.)

PACKAGING: QUARTS, (1) GALLON PAILS, (5) GALLON PAILS AND DRUMS.
