Leak Indicator-Clariant

Heat Transfer Fluid

Edition Date :
October 07, 2022
Leak Indicator-Clariant is a liquid, tinted green, for use as a leak-detection-fluid after mixing with water for double-walled tanks. The product is inhibited without the use of nitrites-, amines-, borates-, silicates- and phosphates. The optimization of the corrosion inhibition system was performed without the use of CMR-substances (cancerogenic, mutagenic, reprotoxic).

Safety

Flash point (DIN 51758) °C119 
Ignition temperature (DIN 51794) °C410
Temperature class (DIN/VDE 0165)-T2
Leak Indicator-Clariant/water mixtures have neither a flash point nor a fire point. Spent Leak Indicator-Clariant/water mixtures can be disposed off in accordance with local regulations. According to the 2nd general administrative regulation relating to the German waste management act of 10.04.1990, reuse is preferable to disposal. The product is recyclable. Leak Indicator-Clariant contains more than 90 % ethylene glycol together with some water and additives, which are present in a well balanced combination and act as corrosion inhibitors with a long-lasting effect. The product is harmful to humans and animals if swallowed. Consult a doctor immediately if the product is swallowed inadvertently. The lethal dose for humans can be assumed to be 100 ml taken at once. In the majority of reported cases of poisoning cerebral damage and pulmonary edemas in particular have been observed besides renal damage. Ethylene glycol, the product on which Leak Indicator-Clariant is based, is classified in water hazard class WGK 1 (slightly water-polluting) according to the list of water-polluting substances (VwVwS from 17.05.1999). This also applies to mixtures of Leak Indicator-Clariant with water. In concentrations up to 1000 mg/l, Leak Indicator-Clariant/water mixtures show no acute harmful effects on fish and bacteria. They are readily biodegradable.

Applications

Leak Indicator-Clariant is officially approved as a detection fluid for double-walled tanks and pipes for the transport of mineral oils. The product can be used for equipment to fill and store fluids hazardous to water as well, if no dangerous reaction with fill mass is possible. This has to be proven for every individual case.
