Delo XLI is based on low toxicity inhibitors and is readily biodegradable. The extended service life characteristic of this product reduces waste due to less frequent fluid disposal. The toxicological and environmental properties of Delo XLI were evaluated by an independent laboratory. The results are listed below: • LD50 >2000 mg/kg (Oral toxicity according to OECD Guideline No. 401) • LC50 >1000 mg/l (Fish toxicity according to OECD Guideline No. 203) • Biodegradability: 92% (18 days) (Test according to OECD Guideline No. 301E)
2. Corrosion Protection
Provides long-life protection against most forms of corrosion on the majority of metals including the aluminum heat transfer surfaces contained in modern engines.
3. Cavitation Protection
Offers cavitation protection without using nitrite or nitritebased supplemental coolant additives (SCAs).
4. Seal Compatibility
Has no adverse effect on rubber hoses and gasket materials as shown in testing a wide range of seal materials.
5. Heat Transfer Efficiency
The carboxylic acid inhibitor inhibitor forms a targeted mono-molecular protective layer on metal surfaces, thus providing efficient heat transfer.
Long life corrosion protection and low additive depletion often result in less maintenance and repair costs.
