Cationic surfactants > for chemical-technical applications

BTC offers cationic surfactants for chemical technical applications where modifying of the surfaces is needed. Such a modifying of surfaces is applied in metal surface treatment applications and it is also considered for corrosion protection. Cationic surfactants are attracted by the negative charged surface of the substrate and thus a film is formed. This film formation is a barrier and protects the substrate.

Brands

Lutron®, Lutensit®

Properties

Quaternary compounds in water provide positive charged units modifying the surface of a substrate by physical processes. Due to their surfactant character they also provide foam properties.

Lutron® and Lutensit® are quaternary compounds. Lutron® is a chlorine-free cationic compound. It is a clear, yellowish liquid with approx. 30% active matter content. Due to its chemical structure it is absorbed to negatively charged substrates. In combination with water-soluble corrosion inhibitors (Korantin® types) Lutron® enables formulations with synergistic effects. The Lutensit® grade is a cationic compound but containing chlorine. It is a colourless liquid formulation.

Applications

Cationic charged groups without chloride ions like BTC’s Lutron® adsorb on the surface of the metal and form a very thin film. This film protects the substrate from corrosion. In particular, steel, aluminium and other non-ferrous metals and their alloys can be protected from corrosion over a wide pH range using Lutron®.

Lutensit® is a cationic component containing chloride and adsorbs to the surface but is not providing corrosion inhibition properties. Especially in the metal surface treatment industry such cationics are used in cleaning bathes to fasten the drying process. Lutensit® is also used for de-emulsification purposes.
