ETONIS® 7850 A
ETONIS® 7850 A is a multi-purpose dispersible polymer powder for concrete, specifically suited for shotcrete, concrete repair, cement admixtures and renders & plasters. It is based on a soft copolymer of vinylacetate and ethylene and belongs to the product class ETONIS® A and it has a neutral effect on rheology and provides the basic properties adhesion and flexibility, giving a high degree of formulation freedom. ETONIS® 7850 A is part of our standard range, offering you the best-in-class solution for a wide variety of applications.
Eigenschaften
• ETONIS® 7850 A makes fresh concrete easier to process and pump because it reduces the frictional forces between cement and aggregates.
•The cohesive properties of ETONIS® 7850 A improve the wrap of cement slurry on aggregates, then increase the bonding strength between cement and aggregates
• ETONIS® 7850 A increase the sedimentation stability of concrete and specialty mortars, reducing bleeding and segregation.
• ETONIS® 7850 A has a plasticizing effect and reduces the water/cement ratio without compromising the concrete's workability.
•The soft copolymer characteristics of ETONIS® 7850 A balance well on compressive and flexural strength of concrete to improve load bearing and durability
• ETONIS® 7850 A improves concrete cohesion and bonding strength with diverse substrates, increases abrasion resistance, enhance freeze/thaw and salt-frost resistance.
•Concrete modified with ETONIS® 7850 A seals against pressing water, shows enhanced carbonation resistance and prevents the ingress of aggressive media into the mix.
•Low emissions

Processing
ETONIS® 7850 A 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® 7850 A 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® 7850 A 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.
