Performance, Features & Benefits of CASTROL BioTac MP are:
- Good protection of equipment under loaded conditions to minimise wear
- BioTac MP provides a strong oil film to give better protection than a lower viscosity oil, at slow speeds and high loads.
- BioTac MP is specifically developed for use in marine applications, providing good resistance to the effects of salt water and corrosion.
- BioTac MP retains its ease of application and flow at lower temperatures than mineral-based alternatives.
- Due to its white colour, BioTac MP stains less than dark greases and better shows contamination making visual inspection far easier.
- Limited strand formation helps to minimise the safety risk posed by grease strings on deck, as well as the potential for water pollution.

Product Description CASTROL BioTac MP
BioTac MPTM is an environmentally responsible, multipurpose EP grease based on a combination of Lithium Complex thickener technology, biodegradable base oil and an optimised performance additive system to impart corrosion protection, oxidation stability and load carrying capability. The inclusion of polymer technology enhances the adhesive properties of the grease, improving water resistance and thus reducing the potential for contamination of both the open deck and the marine environment. Castrol BioTac MPTM has been registered according to OSPAR (Oslo and Paris Convention) requirements and approved by the UK regulators for use offshore. It therefore meets the requirements for being an environmentally acceptable lubricant under the 2013 US Vessel General Permit.

Additional Information
It is preferable to completely remove and clean all used grease from components before applying BioTac MPTM. If this is not feasible, during transition period, it is advisable to apply BioTac MP more frequently, to purge the old grease and monitor the operating conditions to ensure optimum performance. Whilst traditional ways of applying grease on wire ropes may be utilized, use of a proprietary pressurised grease applicator in accordance with manufacturer’s instructions may assist in applying the appropriate quantity of grease and may also help to protect the core of the wire rope. Care should be taken to ensure that only a thin film of grease is applied to the external surfaces of the wire ropes as excessive greasing could potentially lead to contamination of surrounding areas. Crew on board should always ensure that relevant equipment and surfaces are properly lubricated and coated with grease.
Storage
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60C, exposed to hot sun or freezing conditions.
