grotamar® 82

Regulatory reclassification of grotamar ®82 in the European Union

grotamar ®82 is designed to safeguard fuel tanks and engines in boats, ships, trucks and other vehicles and vessels against the effects of diesel contamination. It has been widely used by the general public for many years.

However, a reclassification of chemicals in the European Union, Iceland, Liechtenstein, Norway, and Switzerland by The Risk Assessment Committee (RAC) of ECHA means the use of this product by the general public is now prohibited, and it may only be handled by professionals.

How can our customers prevent microbial contamination of diesel?
You will still be able to protect your tanks and engines with grotamar ®82; however you will not be permitted to buy or apply it directly. Instead, you can request your supplier to put grotamar ®82 in your vehicle or vessel. As long as the product is applied by them and in their name, this is considered professional use, and complies with the new rules.

Please note that this only applies to the European Union, Iceland, Liechtenstein, Norway, and Switzerland.


The first biocide with a new protective formula for modern diesel fuels

grotamar® 82 is a versatile additive and can be used in all types of diesel fuel and heating oil, each with bio diesel up to 20% and also in pure mineral oil diesel without bio component.
