About ACL
Additiv-Chemie Luers GmbH & Co. KG (ACL) is an independent manufacturer of additives for metalworking fluids, industrial lubricants, cleaners, corrosion protection agents and specialties. The portfolio includes synthetic and natural sodium, barium and calcium sulfonates, EP and AW performance additives, corrosion inhibitors, surfactants, fatty acid amides, esters, defoamers and custom additive packages, among others for hydraulic oils according to DIN 51524. In addition to standard products, ACL develops tailored formulations in close collaboration with customers, with a focus on products with an improved sustainability profile, for example through biobased components and reduced hazard labeling. Production takes place at the Delmenhorst site with über 80 heatable and coolable mixing and tank vessels, a sulfonation plant and three production halls. The company is part of the Diersch & Schröder Group and supplies customers in around 50 countries in Europe, Asia, Africa, North and South America as well as Australia. Subsidiaries and shareholdings are Alpha Chemie GmbH (Freital) and EstiChem A/S (Denmark).

Products and Raw Materials
Sodium sulfonates
Core of the product range; synthetic, natural and mineral-oil-free, molecular weights 420–600 g/mol, with corrosion protection and emulsifying capability.
Barium sulfonates
Neutral and overbased types for corrosion protection with good demulsifying properties.
Calcium sulfonates
In neutral and overbased form a component of EP additives and rust inhibitors.
Amine borates and amine carboxylates
Corrosion inhibitors for water-soluble and water-miscible coolants, standardly DEA-free.
Phosphoric acid esters (AW additives)
Oil-soluble and water-miscible AW additives with excellent wear protection and corrosion protection properties.
Polysulfides TPS® 20/32/44 (Arkema)
Sulfurized EP additives, for which ACL acts as distribution partner in DACH, PL, SK, CZ and TR.
Synthetic mono- and pentaerythritol esters
Esters with high hydrolytic stability and good lubricating properties for metalworking fluids and release agents.
Fatty acid amides and ethoxylated fatty alcohols
Co-emulsifiers and emulsifiers for water-miscible metalworking fluids and cleaners.
Non-ferrous metal inhibitors (benzotriazole, tolyltriazole)
Oil- and water-soluble protection for copper, brass, red brass and bronze.
Oxidates and butyl esters
Based on oxidized waxes and white oils, component of temporary corrosion protection agents.
