- Biodegradable and non-toxic
HYDROX BIO 150 will absorb sea or fresh water entering the sterntube to form a fluid emulsion. This reduces the risk of free water being present and continues to provide the required lubrication and corrosion protection. (Conventional oils do not emulsify in the same way and tend to separate, exposing components to free water and potential wear damage.)
HYDROX BIO lubricants achieve a biodegradability of greater than 60% in the 28 day OECD 301B and OECD 306 tests and are considered non-toxic in the marine environment based on the following results:
|LC50 exceeds 1000 mg/l||EC50 exceeds 1000 mg/l||EC50 exceeds 1000 mg/l|
HYDROX BIO 150 meets the detailed ecological definitions and requirements laid down in the 2013 Vessel General Permit (VGP) published by the US EPA in March 2013.
HYDROX BIO 150 is for use if the shipyard recommends an ISO VG 150 sterntube EAL in order to give improved oil film thickness under severe conditions as may arise if the aft bearing is subject to edge loading. This can occur when the design tolerances or other factors are marginal.
This product is approved by many of the leading OEMs such as KEMEL, SKF Marine (B+V) and Wärtsilä and for up to 5 years when used with OEM elastomers recommended for EALs. For specific details please contact us.
