ASCOTEC® designs, manufactures and markets ranges of liquid anticorrosion additives, namely ASCONIUM®, ASCOTRAN® and ASCOTRUST® that meet almost all needs. These innovative additives, efficient and eco-aware, can be used in various fields such as paints, metallurgy and cleansing products.
Over the years, ASCOTEC® has developed an expertise serving its customers by offering customized solutions as well as a well-tried technical support.
ASCOTEC’s portfolio:
ASCONIUM® are organic liquid-type additives which can provide excellent long-term anticorrosion performance to pigmented or clear coatings. They can be used as the sole anticorrosion additive or combined with other anticorrosion pigments to improve their performance. As liquids, they are easy to incorporate into coatings’ formulations and will not reduce the gloss of the coating’s dry film, and can be used in a wide range of either waterborne or solvent-based coatings for Industry, Architecture or Do It Yourself.
ASCONIUM’s Key Benefits:
- Highly efficient at low dosage
- Improve films’ water resistance
- Usable in clear coatings
- Multi-metal protection
- Maintain film gloss
- Improve paint adhesion
- Reduce film blistering

ASCOTRAN®– Flash-rust inhibitor for water-based coatings
Flash rust inhibitors:
Every time a waterborne coating is applied on metal, flash-rust phenomenon, which is immediate corrosion of metal substrates, is of concern. ASCOTEC® has developed a complete range of bio-based flash-rust inhibitors containing bio-based substances that are effective in many different situations, whatever the substrate which needs to be protected or the coatings nature will be.
The product range:
- ASCOTRAN-H10- the most universal
- ASCOTRAN-H14- multi-metal substrates and high water-resistance properties
- ASCOTRAN-H30-for very sensitive flash-rust substrates
- ASCOTRAN-H18-high compatibility level, including into 2K systems
- ASCOTRAN-AL4-multi-metal systems; nitrite free
- ASCOTRAN-HPB- complies with most international & national standards for eco-friendly labels, nitrite free.
Anticorrosion Additives for Coolants / Antifreeze / Heat Transfer Fluids
In the absence of any adequate treatment, Heat transfer fluids, based on glycols, alcohols or mineral salts, can cause many disorders, like corrosion. They can affect all components making up the circuit (generators, exchangers, pipes, circulation pumps…).
To solve these corrosion problems in circuits, ASCOTEC® offers efficient anticorrosion additives, Organic Acid Technology type, meeting almost all the needs in this type of application.
The product range:
- ASCOTRAN-RCX- for glycol-based engine coolants
- ASCOTRAN-R- for machines, boilers and solar panel heat transfer fluids
- ASCOTRAN-DMC- for organic salts-based heat transfer fluids
- ASCOTRAN-BR1- for CaCl2-based fluids
- ASCOTRAN-R4D- for low conductivity heat transfer fluids
Anticorrosion Additives for Metalworking
During metal working processes, metals are in contact with fluids of different natures and of different functions : lubricants, degreasers, cutting oils, grinding fluids, etc… These fluids must protect both the metals and cutting tools from corrosion. Water-based fluids (emulsions or solutions) are more and more replacing mineral fluids, but are more harmful and difficult to dispose. It is the reason why ASCOTEC® has developed a complete range of anticorrosion additives for metal working, designed for each application.
Key Features:
- VOC Free
- Fully hydro-soluble
- Nitrite & Borate free
- Heavy metal free
- Multi-metal protection
The Product Range:
ASCOTRAN-L- the most universal
ASCOTRAN-L44- reinforced protection of aluminum alloys
ASCOTRAN-NSC- reinforced protection of yellow metals
Anticorrosion Additives for Metal packaging Protection
Cleansing and maintenance products are highly corrosive and can cause corrosion of metallic packaging (as aerosol cans) which contain them. With its range of anticorrosion additives ASCOTRAN®, ASCOTEC® can offer the ideal solution for each system.
Anticorrosion Additives for Metal Cleaners
Before painting or receiving surface treatment, metals can be cleaned or stripped; these processes can be very aggressive / corrosive to the metal. Either in the household or industrial segment, corrosion problems can be addressed in the same way.
Key Features:
- Cover a wide range of pH
- Heavy metal free
- Cover a wide range of metals
- Low use dosages
- Nitrite & Borate free
The Product Range:

- ASCOTRAN-Z- Reinforced protection of Zinc and Zinc alloys
- ASCOTRAN-110C- Protection of solvent-borne paint removers
Anticorrosion Additives for Hydrostatic Tests
A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, (which may be dyed to aid in visual leak detection) and pressurization of the vessel to the specified test pressure. During the test procedure, corrosion of metallic parts of the device can occur due to the contact with water, even if only for a short time.
ASCOTEC® has developed a specific corrosion inhibitor for this application, ASCOTRAN®-L. When added to the test process water at very low dosages, the ASCOTRAN®-L provides a total protection of metallic elements, both during and after the test procedure.
Key Benefits:
- VOC free
- Heavy metal free
- Multi-metal protection
- Low use dosages
- Nitrite and Borate free
Anticorrosion Additives for Metals Temporary Protection
During machining, metals can be stored for varying periods of time and be exposed to an aggressive environment such as humidity or polluting gases.
Corrosion developing on the surface will then disturb subsequent operations (coating application, chemical treatment, etc.). Protection during these periods is then necessary. We refer to this as temporary or inter-stage protection.
Anticorrosion additives developed by ASCOTEC® for temporary protection are the ideal solution to replace greases and protecting varnishes which are often difficult to remove and not easy to use. The way ASCOTRAN® will interact is very specific. Their barrier effect is ensured by the formation of a monolayer of chemically sorbed molecules on the metal surface. There is no need to eliminate this molecular protecting film before an assembly or painting operation.
The Range:
- ASCOTRAN-L – Ferrous metals protection in aqueous media
- ASCOTRAN-L13 – ferrous metal protection for mineral and solvent-based media
- ASCOTRAN-NSC – multi-metal protection for aqueous media
ASCOTRUST® – Rust converter additives
ASCOTRUST® is a range of innovative, liquid-form, and tannic acid-free rust-converting additives for waterborne coatings that is ecolabel compliant and VOC free.
These additives provide rust-converting properties to the coating layer and enable direct applications on rust or on poorly prepared substrates.
They ensure an efficient rust-blocking effect as soon as the paint is applied and form a passivation layer between the substrate and the coating layer; this helps to maintain the coating’s anticorrosion performance, despite adverse substrate conditions.
They can be used in both waterborne clear-coatings and paints. A waterborne anticorrosion clear-coating containing ASCOTRUST® can be used as a rust-converting pre-treatment which will perform better than tannic acid-based formulations or solvent borne alkyd-based oils.
A waterborne metal paint based on ASCOTRUST® provides the following properties:
- Prevention of the rust “migration” through the paint layer, even on recently rusted surfaces.
- Preserving the coating’s color.
- Avoiding strong de-rusting operations before painting, without loss of performance.
- Not compromising the coating anticorrosion performance on non-rusted substrates.
In addition, ASCOTRUST® completes the action of the antiflash-rust additive on very reactive substrates.
The Product Range:
- ASCOTRUST-X1-The most universal. Ideal for iron oxide-based coatings
- ASCOTRUST-X2- Good compatibility in clear coatings
- ASCOTRUST-X3- High synergy with flash-rust inhibitors. Mainly used for primers.
- ASCOTRUST-X4- High water resistance. Ideal for DTM coatings.
