Bentone is an absorbent aluminium phyllosilicate, essentially a fine clay used as a non-melting thickener.
Bentone has a high drop point, up to 300°C. This is used as a thickener to give grease/gels good water resistance as well as good mechanical operating stability.
Bentone gels have a low sensitivity to temperature variations and therefore provide greater dynamic viscosity and temperature stability.
The IKV Lubricants bentone thickened grease/gel range includes:-
IKV TRIBOSTAR MGI 462 is a high viscosity mineral oil with bentone thickener. It does not melt or become fluid at high temperatures. It has good anti-corrosion properties and good resistance to high loads. It is compatible with most good quality seals and is ideal for use on bearings, slides and gears operating at high temperatures.
IKV TRIBOSTAR MGI 461 BM is a medium to high viscosity oil with bentone thickener. It is reinforced with Molybdenum Di-sulphide (MoS2) as a boundary lubricant and EP additive. It is non-melting and ideal at high temperatures.
IKV TRIBOSTAR PGI 42 is a PAO with bentone thickener. It is ideal for use on bearings subject to high temperatures or high rotation speeds or where a weak torque resistance is required.
IKV TRIBOSTAR PGI 102 contains a medium viscosity synthetic base oil with bentone thickener. It offers excellent corrosion protection, resistance to high loads and good mechanical stability.
IKV TRIBOSTAR EGI 102 GM is a synthetic ester with bentone thickener. It is for use on bearings subject to very high temperatures and heavy loads.
IKV TRIBOSTAR MGI 102 is an inorganic grease without dropping point for special applications in high and low temperatures. It has a mineral base and is NLGI grade 2. The working temperature is -10 to 150°C.
IKV TRIBOSTAR BGI 12 is an inorganic grease without dropping point for special applications in high and low temperatures. It has a synthetic base and is NLGI grade 1/2. The working temperature is -50 to 130°C.
