ESTIMOL®

Self-emulsifying lubricant esters

ESTIMOL® esters are multi-functional esters based on alkoxylated polyols, diacids and monocarboxylic acids. ESTIMOL® is applied in industrial, functional fluids and improves two or more of the following properties:

  • Lubricity
  • Emulsion stability
  • Corrosion inhibition
  • Coupling activity

ESTIMOL® TE esters:

The TE series consists of an alkoxylated complex ester, nonionic in nature, with excellent lubricating properties.

ESTIMOL TE 2000 N is soluble in water and find applications in metal forming lubricants, release agents and other water-miscible lubricants for example for renovation of sewage systems with polymer inner-liners.

Esters multi-functional esters based on alkoxylated polyols, diacids and monocarboxylic acids
ESTILUBE C-series gives superior lubricating and emulsifying properties in water miscible functional fluids.

ESTIMOL® C Esters

The C-series contains esters with a free carboxylic acid group that is neutralized by alkanolamines in the fluid concentrate. The multi-functionality gives superior lubricating and emulsifying properties in water miscible functional fluids.

ESTIMOL CX-N is a lubricating additive package for use “as-is” in both concentrates and as tank-side additive. Commercial applications of ESTIMOL® are found in water-miscible cutting fluids, deep-drawing lubricants, release agents and emulsifier packages. ESTIMOL CX-N is primary applied as tank-side additive, whereas ESTIMOL CE 960 NN is used as formulation component in the concentrate.

FAQ about ESTIMOL®

ESTIMOL® esters bring extraordinary lubricant properties to aqueous lubricant formulations.

The main application of ESTIMOL is in metal working fluids, but ESTIMOL® esters also find applications in other types of water-miscible lubricants such as release agents and lubricants used in renovation of sewage piping with polymer inner-liners.

ESTIMOL® products are free from chemical hazard labelling (CLP labelling), they are biodegradable and easy to formulate into water-miscible lubricants

ESTIMOL TE 2000 N is a nonionic, alkoxylated oligo-ester, which is soluble in water. When applied in hard water, it is recommended to add a small amount of sequestering agent to get a 100% clear solution. Mixtures between water and ESTIMOL TE 2000 show an extremely high viscosity around 40% ESTIMOL TE 2000, which makes the lubricant adhere to the surface. The lubricant may be formulated with a lower active content, and the increase in viscosity in then seen after application on the surface, when the water starts to evaporate.

ESTIMOL CE 960 NN is an anionic, alkoxylated ester, which is supplied on its acidic form. The acid value is neutralised by alkanol amines as a part of the formulation of the metal working fluid. When neutralised in the formulation, ESTIMOL CE 960 NN has emulsifying, corrosion protection and lubricant properties – all in one molecule!

ESTIMOL CX-N is a self-emulsifying, lubricant additive, which may be applied in the metal working fluid concentrate or as tank-side lubricant additive for metal working processes that require extra lubricity.
