Cemprotec E942 - cementitious coating for the protection of steel and concrete
(en1504-2)

Flexcrete's Cemprotec E942 is a major advancement in coating technology incorporating the benefits of copolymer and epoxy resin technologies into a water based cementitious system. These chemically combine to give a hard, durable coating with excellent resistance to water, chloride ions, oxygen and aggressive chemicals for the protection of steel and concrete in the most demanding environments.

Cemprotec E942 is a two component, water based, epoxy and cementitious modified polymer coating for the protection of concrete and ferrous metals. It incorporates advanced cement chemistry, microsilica, fibre, epoxy and styrene acrylic copolymer technology to provide multi-functional protection with enhanced chemical resistance. When mixed, it exhibits a high degree of thixotropy to enable ease of application by brush or spray techniques and gives a smooth surface finish with no sagging even in vertical situations. It hydrates to form a dense, highly alkaline coating, exhibiting both polymeric and resinous properties, which offers low permeability to water and provides very high diffusion resistance to chloride ions and oxygen, to ensure long term protection. It is specially formulated to chemically accelerate the passivation of ferrous metals and give maximum adhesion to steel and concrete. Proven to be suitable for use in conjunction with cathodic protection systems at temperatures upto 95°C.

Advantages of Cemprotec E942

Simple: Materials are pre-packaged in a convenient and easy to handle size, requiring only mixing on site.
Thixotropic: A unique blend of surfactants enables easy brush or spray application. Gel structure breaks down under shear to produce a smooth finish, which rapidly recovers to prevent sagging.
Resistant: Excellent abrasion and impact resistance. Very high resistance to a wide range of aggressive chemicals.
Adhesive: Excellent adhesion to steel and cementitious substrates. Tolerant to lower levels of steel preparation.
Self Priming: Hydrates to provide an alkaline environment which chemically reacts with the substrate to accelerate the re-passivation of steel and enhance the bond to concrete.
Safe: Water-based product which cures without the release of hazardous solvents. Equipment easily cleaned with water.
Low Permeability: Dense matrix offers low permeability to water, even at 10 bar pressure, and very high diffusion resistance to chlorides and oxygen.
