DESCRIPTION CPD ® Latex Modifier 1186 is a carboxylated styrene butadiene latex emulsion. When added to Portland cement concrete, the physical properties and chemical resistance of the concrete are enhanced considerably. WHERE TO USE Applications include overlayment and repair of concrete bridge decks and bonding agent for concrete and grout overlays.

Formulation and Physical Characteristics:
Portland cement Type 10 43 kg (94 lbs.) Concrete sand 107 kg (235 lbs.) Crushed stone 3/8"(9.5mm) 85 kg (188 lbs.) Latex Modifier 13.2L (3.5 U.S. gal) Water 9.97 kg (22 lb) maximum (includes moisture content of aggregate) Water/cement Ratio 0.3-0.4
The above ingredients should be added to the mixer and blended for three minutes. Specimens should be cast, and allowed to cure for 28 days. Batch mixed concrete samples should be carefully prepared to minimize air entrainment. It is suggested that the sequence of addition be: crushed stone, sand, CPD® Latex Modifier 1186, cement and water. Specimens should be cast in accordance with A.C.I. practices. For the first 24 hours, the specimens should be kept covered with wet burlap (and the burlap covered with polyethylene film) before it is removed from the mold. The specimen is then air cured for an additional 27 day period before testing.

APPLICATION
Concrete modified with CPD® Latex Modifier 1186 may be mixed in a batch type mixer, however, extreme care should be taken in batch mixed situations to avoid excessive air entrainment. Because of this, most polymer modified concrete is mixed in a continuous mixer such as a Daffin concrete mobile mixer where the mixing time is a matter of seconds. Finishing equipment, such as the Bidwell or Gomaco Roller Finisher, produces an excellent, well compacted, smooth overlay. Actual elapsed working time is dependent upon temperature, humidity and wind velocity. CPD ® Latex Modifier 1186 modified overlays must be covered with wet burlap and polyethylene film immediately after finishing, and damp cured for a minimum of 24 hours, followed by 72 hours dry curing. A cure hour is one in which the minimum temperature is 10°C (50°F). LIMITATIONS
PACKAGING 208L (55 U.S. gal) - 210 kg (500 lbs.) 18.9L (5 U.S. gal) pail - 19 kg. (45 lbs.)
STANDARDS Approved for use on all MTO & MTQ (Ministry of Transportation) projects.
STORAGE Although CPD® Latex Modifier 1186 is freeze-thaw stable, it is recommended that it be stored where its temperature would be between 10-29°C (50-85°F). To avoid possible difficulties in finishing the latex modified overlay the latex temperature should be between 7.2-29.4°C (45-85°F) when used. SHELF LIFE One year from date of manufacture when stored in original unopened container, under normal heated warehouse conditions.
