ETONIS® 7930 A (PRC)

ETONIS® 7930 A (PRC) is a hard dispersible polymer powder based on vinyl acetate and ethylene for very good tensile adhesion strength on inorganic surfaces combined with good workability. ETONIS® 7930 A (PRC) contains a fine mineral filler as antiblocking agent. It is produced without the addition of organic solvents, plasticizers and film-forming agents.


ETONIS® 7930 A (PRC) makes fresh concrete easier to process and pump because it reduces the frictional forces between cement and aggregates. The cohesive properties of ETONIS® 7930 A (PRC) increase the sedimentation stability of concrete and specialty mortars, reducing bleeding and segregation. ETONIS® 7930 A (PRC) has a plasticizing effect and reduces the water/cement ratio without compromising the concrete's workability. In hardened concrete, ETONIS® 7930 A (PRC) improves adhesion, enhances flexural strength, and increases abrasion resistance. It does not impair the concrete's high ultimate strength. Concrete modified with ETONIS® 7930 A (PRC) seals against pressing water, shows enhanced carbonation resistant and prevents the ingress of aggressive media into the mix. In combination with suitable foam-control agents, ETONIS® 7930 A (PRC) also increases compressive and flexural strength.
ETONIS® 7930 A (PRC) is a hard general-purpose powder and has no effect on rheological properties. It is eminently suitable for formulating compounds of high ultimate strength.
ETONIS® 7930 A (PRC) may be added in powder form either to the dry concrete mix or the fresh mixed liquid concrete. Pumping and mixing cause the polymer powder to redisperse rapidly in the gauging water. Alternatively, ETONIS® 7930 A (PRC) may first be mixed with gauging water and then added with it to the dry-mix or liquid concrete. Protracted stirring of the polymer/water mixture is apt to cause individual components to settle out, but brief mixing will produce a homogenous mixture again. The amount of ETONIS® 7930 A (PRC) needed to modify concrete ranges from 2.5 - 10 wt. % relative to the quantity of cement. The amounts used in special applications such as mortar and cementitious coatings may be considerably higher. The exact amount will depend on the requirements profile.
Practical benefits ETONIS® 7930 A (PRC) contains no water, so transport costs are less than for standard dispersions. Using ETONIS® 7930 A (PRC) cuts system costs by reducing material consumption (e.g. rebound), time and labor. Overall, energy costs are reduced.
ETONIS® 7930 A (PRC) is suitable for modifying concrete, concrete repair, specialty mortar and soil treatment for infrastructure products, in particular for concrete repair applications in road, bridge and tunnel construction.
