Zschimmer & Schwarz offers phosphonates and surfactants for a variety of different application areas. With products from a single source, we provide tailor-made solutions for our customers’ requirements:
CUBLEN phosphonates are the products of choice for use as high-performance antiscalants, dispersants and chelating agents or as corrosion inhibitors.
Our surfactants stand for multifunctionality, efficiency and sustainability. For example, products from our hydrotropic surfactant range are ideal for the clarification and stabilisation of alkaline or electrolyte-containing formulations.

The CUBLEN A series (ATMP) is a good complexing agent and a universally applicable inhibitor for various mineral deposits (scale). Selected ATMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water. CUBLEN ACS 402 is also compatible with active chlorine.
The CUBLEN B series (BHMTMP) is an excellent inhibitor for both carbonate- and sulphate-based mineral deposits with high hydrothermal stability.
The CUBLEN D series (DTPMP) represents the most versatile phosphonic acid in the CUBLEN product range and impresses with its outstanding price–performance ratio. DTPMP is an excellent inhibitor for mineral deposits (for example CaCO3, BaSO4, SrSO4) and a powerful complexing agent. Selected DTPMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water.
The CUBLEN E series (EDTMP) is a particularly powerful complexing agent with high calcium tolerance. EDTMP has a high dispersing power for ceramic slurries and retards setting in building materials.
The CUBLEN F series (HDTMP) acts as an excellent inhibitor for mineral deposits (especially for gypsum) and has high hydrothermal stability. HDTMP shows corrosion-inhibiting properties on aluminium under alkaline conditions. Selected HDTMP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water.
The CUBLEN K series (HEDP) is a very good CaCO3 inhibitor, water hardness stabiliser and complexing agent for trivalent metal ions (for example Fe3+). Selected HEDP products are certified according to the North American standard NSF/ANSI/CAN 60 for use in the production of drinking water. In addition to aqueous products, HEDP is also available as a granular, dust-free solid with various active contents.
The CUBLEN R series (HEMPA) is an excellent dispersant for calcium-based deposits. HEMPA significantly improves the rinsing properties of washing and cleaning formulations.
In highly saline systems of oilfield applications, HEMPA shows its excellent calcium tolerance.
The CUBLEN P series (PBTC) consists of an active chlorine-compatible phosphonic acid with high calcium tolerance – even under strongly alkaline conditions.
CUBLEN phosphonates are also used in secondary mineral oil production. They are used both in topside and downhole treatment. They stabilise water with a very high salt and/or sediment load and prevent the formation of mineral deposits of sparingly soluble salts. Furthermore, they disperse mineral or sediment particles that have already formed.
CUBLEN phosphonates are an integral constituent of packages for effective water treatment. As powerful threshold-active substances, they prevent the deposition of insoluble carbonate- and sulphate-based minerals and counteract fouling thanks to their good dispersing properties. Furthermore, phosphonates are good corrosion inhibitors, especially in combination with other inhibitors. In addition to individual phosphonates, Zschimmer & Schwarz also offers synergistic mixtures for special applications such as reverse osmosis.
CUBLEN phosphonates present a valuable contribution to the building materials industry. Due to their dispersing properties, they are used as plasticisers or rheology modifiers in ceramic slurries and as stabilisers in pigment paints. In addition, CUBLEN phosphonates are also used as setting retarders for concrete or gypsum.
CUBLEN phosphonates are high-performance complexing agents. They are required in paper and pulp production to bind heavy metals and in this way increase the efficiency of bleaching baths. Furthermore, CUBLEN phosphonate complexing agents help to remove heavy metals and alkaline earth metal compounds from raw cotton (demineralisation).
CUBLEN phosphonates are ideally suited as additives for cleaning corroded metal surfaces. Both the acidic effect of phosphonic acids and their complexing character can accelerate the removal of rust, for example, and at the same time provide temporary corrosion protection for the cleaned surfaces. CUBLEN phosphonates are an environmentally friendly alternative to cyanide complexing agents for galvanic coating baths.
In addition to the extensive standard phosphonate range, Zschimmer & Schwarz offers a large number of products with special properties for special applications. In addition to oxidation-stable modifications of ATMP (CUBLEN ACS 402), there are also chloride-free products based on CUBLEN series E and D, for example. Furthermore, Zschimmer & Schwarz boasts a readily biodegradable aminomethylene phosphonate (according to OECD Standard 301) with novel surface-active, corrosion-inhibiting and hydrotropic properties.
Zschimmer & Schwarz also offers proprietary formulations consisting of phosphonates and other auxiliaries which have been optimised for use in certain fields of application. Thanks to the application of our long-standing expertise, these synergistic mixtures impress with their enhanced performance compared to individual products, thereby creating significant added value for the customer.
In addition to aqueous solutions, the CUBLEN product range also comprises phosphonates/phosphonic acids which are available either as dust-free granulated solids or as crystalline powder. The spectrum of products we offer ranges from industrial-grade solids with a large production volume to fine chemicals of high purity.
