FUCHS LUBRITECH - Concrete Realease Agents with an optimum effect

The composition of concrete release agents

Concrete release agents consist of a base fluid in which the required additives are dissolved. This base fluid can be mineral oil with and without de-aromatised white spirit, ester/vegetable oil or, in the case of emulsions, water. Fatty acids and/or esters are usually used as separating substances. The fatty acids react chemically with the cations of the “concrete water” to produce metal soaps, which form the “predetermined breaking point” between concrete and form following the hardening of the

concrete. The often utilised esters are saponified to form fatty acids and alcohol by the highly alkaline concrete (pH value 12.9). The fatty acids react, as described, with the cations in the “concrete water”. The alcohol is built into the cement matrix. Furthermore the concrete release agents contain additives for the minimisation of pores and shrinkage cavities as well as a temporary corrosion protection for steel forms.

The concrete release agents (SOK) are divided into the following three main groups with regard to their raw material basis:

Product	Group 1 Mineral oil basis, partly with solvents	Group 2 Emulsions	Group 3 Ester-oil release agent
Carrier substance	Mineral oils/partly also solvents (approx. 80 to 95%)	Water (approx. 65 to 85%)	Vegetable oils, ester oils (approx. 95 to 99%)
Separating substance	Fatty acids and esters (approx. 2 to 15%)	Fatty acids, esters and partly also hydrocarbons	Vegetable oils, esters (approx. 95 to 99%)
Additives for minimising pores and shrinkage cavities	yes	yes	yes
Rust protection additives	yes	yes	yes

Mineral oil based release agents

Inexpensive release agents, whose technical effectiveness does not usually correspond to the performance of the products used in precast plants, are used for normal requirements in structural and civil engineering. Precast plants often utilise release agents based on mineral oil - sometimes mixed with solvents. The technical requirements in this segment are very high. Corrosion quite often occurs on the steel form, particularly in the production of ceilings and walls. FUCHS LUBRITECH has developed special concrete release agents with increased corrosion protection.

Ester or vegetable oil based release agents

Biogenic release agents on an ester or vegetable oil basis are normally used for special applications, such as on bottom pallets in pipe manufacturing and in drinking water protection areas. Due to their high viscosity these products are usable only to a limited extent in winter.

Emulsion based release agents

For reasons of health and safety at work and environmental hygiene, water-based products are increasingly used in stationary production plants. FUCHS LUBRITECH successfully brought emulsions onto the market years ago under the name SOK AQUA. Work is continuing intensively and sustainably to further extend and push the range of emulsions. It goes without saying that the majority of the concrete release agents from the FUCHS LUBRITECH SOK range are easily biologically degradable in accordance with the OECD tests and correspond at the most to the German water pollution class 1 (WGK ).
