Ec-135

ConTec EC-135

DESCRIPTION

ConTec EC-135 is a integral water repellant admixture used in low slump concrete units such as architectural block, paving stones, SRW units, or masonry mortar. When used properly this unique formulation chemically reacts with concrete to prevent water penetration and control efflorescence. ConTec EC-135 contains new and improved primary efflorescence control and enhances the color and appeal of all types of concrete products. When used in both mortar and masonry units EC-135 reduces water infiltration through masonry walls.

APPLICATION

Use ConTec EC-135 in all types of manufactured concrete in which the reduction of efflorescence and water permeability is desirable.

PACKAGING

FEATURES / BENEFITS

●   Increases hydrophobic properties and  lowers absorption rates.
●   Impedes the formation of primary and secondary efflorescence.
●   Increases product durability with its unique densifying properties.
●   Aids color development and can shorten production cycles.
●   Reduces mechanical abrasion in equipment

HANDLING / STORAGE

ConTec EC-135 should be stored at temperatures above 40°F (4.5°C)  Care should be taken to prevent this product from freezing. Should EC-135 become frozen the resulting material will be unusable.

ADDITION RATES

We recommend the following range of dosage: 8 to 16 fluid ounces per hundred weight of cement for concrete paving stones and concrete roof tile. For SRW units and other architectural block higher dosage rates may be recommended. These dosage rates are estimated, your actual rate should be determined by testing. We recommend the assistance of an ICT technical representative to help you determine the proper dosage rate and order of addition for your particular process. Order of addition procedures can vary per facility. Never mix EC-135 with other admixtures before application.
