Those who passivate earlier run into less trouble later. Whether it’s in pharmaceuticals, food production, semiconductors, or automotive supply – wherever processes are running, you can be sure there’s water running, too. And it’s basically the same in electrical engineering, chemicals, petrochemicals, railways, and shipping – all industries where water (steam) is typically indispensable.
When it comes to heat exchangers and cooling systems or steam boilers, for you as the responsible engineer, this means one thing above all: the equipment and the medium are of equal importance. Only if you have 100% clarity about the water quality will your systems run reliably, economically and, above all, faultlessly.
The problem is that the valuable resource water often has different characteristics depending on its region and source of origin. Constituents like magnesium, calcium, sodium, potassium, or iron can enrich the water, and in some cases you actively want these minerals to be in it. Some water, however, is polluted with heavy metals, nitrates, germs, or bacteria – making it difficult or even impossible to use that water without treating it first.
The rule is: only when you have all environmental parameters under control and the water quality is just right will the quality of your processes and products be equally assured. The technical solution of choice is often deionized or softened water. While it does have to be prepared in elaborate processes, it makes up for that with its barely detectable electrical conductivity. Except, it doesn’t solve the problem of corrosion. Unwanted reactions between metals and deionized and/or softened water cannot be prevented, and can in fact become even worse.
Corrosion can occur anywhere, at differing degrees of severity. The only way to influence this is through parameters you have control over, such as the choice of equipment design or measures for maximum reduction of oxygen ingress into a system. And don’t forget the materials used. Whether non-alloy iron or copper compounds, aluminium, or stainless steel is used – these are also decisive as to the risk of corrosion.
So, if you also wish to increase process stability and system reliability without increasing effort, for virtually all materials, you would be making an excellent choice with our film-forming amines. With our high quality amines, you take care of the metal passivation of your systems inside containers and piping systems – quickly and easily.
The results will speak for themselves: after employing our film-forming amines, the corrosion in your pipeline network or tank will noticeably recede; and for new installations, it may never even set in at all.
Conversely, this also means that in the event of oxygen ingress, maintenance work, or even prolonged standstills, the risk of corrosion of metal-passivated systems is proactively minimized. Another advantage: film-forming amines have a cleaning effect and mobilize deposits and any oxide layers that have already formed. This makes it an ideal helper for cleaning old systems as a first step before establishing effective protection in the second step – for the prolonged service life of your systems.
There is another thing that speaks for using our high quality amines: avoiding deposits of iron oxide layers on the inner walls of boilers and pipelines quantifiably increases heat capacity. This has a positive effect on the balance sheet especially for operators of heat recovery systems or hospitals with water boilers, for example. The water and/or gas costs of a system are measurably reduced.
As the engineer in charge, are you looking for alternative ways to improve your heat capacities and lower your operating costs?

All in all, we are proud to be able to help companies save energy and water with our film-forming amines and thus help reduce their CO2 footprint.
You will be impressed with the versatility of the new generation of anticorrosion additives: whether it’s for industrial heating circuits, ceiling cooling, or even an antique steam locomotive boiler.
We don’t like to think about them, but they can still be an issue in the industrial reality: leaks and accidents. If worst comes to worst and process water ever does escape, our film-forming amines also ensure that, with monitored system drainage, no harm comes to people or the environment.
Moreover, our film-forming amines like to show off what they can do! As a service technician, you can perform a routine check at any time: simply use our test kit to determine the free amine quantity in your water and thus the degree of protection of your equipment. Using a test strip, a colour scale and a water sample, you will know the prevailing “parts per million” (ppm) in a matter of minutes, which you can simply extrapolate to your total volume or to the given amount of water. Monitoring water quality, and with it system efficiency, has never been easier.
Our film-forming amines keep their promises. More than just oxide layers:
