MX-510

Thickening System for Oil Systems

Manalox 510 is a reactive form of poly-oxoaluminum stearate capable of thickening and gelling many types of aromatic, and non-aromatic petroleum distillates oils including white oils, kerosene, diesel fuel, fuel oils, and naphthenic oils. MX-510 comes supplied as 60% aluminum alkoxide in technical white oil solvent and offers the following benefits.

  • Liquid – ease of handling

  • Reactive form of Aluminum Stearate – provides rapid thickening

  • Excellent solubility – soluble in a variety of aliphatic, aromatic, and naphthenic hydrocarbons

  • Consistency – the overall aluminum content is tightly controlled resulting in a more consistent product

  • Non-hazardous classification – not considered flammable per shipping regulations

Use Information

MX-510 can be used to thicken and/or gel inert oils and solvents. The degree of thickening is controlled by the amount of MX-510 added. The rate at which the oil thickens is temperature dependent. The level of MX-510 required varies depending on the type of oil used and the gel structure desired, but generally falls between 4.0% and 8.0% by volume relative to oil. Thickening is accomplished by reacting MX-510 with suitable fatty acids and a small amount of moisture, forming aluminum soaps in-situ in the solvent. The type of gel structure obtained can range from stringy to buttery depending on the choice of fatty acid used.

Example Formulations

Example 1

Parts by weight
Petroleum oil91
MX-5104.0
Ricinoleic acid5.0

Dissolve the MX-510 in the petroleum oil followed by the ricinoleic acid. Mix well then let stand to develop gel. Ratios of reactants may be changed to modify end results.

Example 2

Parts by weight
Petroleum oil91
MX-5104.0
2-ethylheanoic acid4.5
Water0.5

Dissolve the MX-510 in the petroleum oil followed by the 2-ethylhexanoic acid. Mix well and leave for one hour. Add water and mix thoroughly. Let stand to develop gel.

HANDLING AND STORAGE OF MX-510

MX-510 will react rapidly and irreversibly with atmospheric moisture to form partial hydrolysis products with consequent loss in expected chemical reactivity. Drum quantities should be stored in dry surroundings, away from the possibility of water collecting on the lids. Laboratory quantities should be kept tightly sealed to maintain reactivity. Partial hydrolysis is evidenced by a skin quickly forming on exposure to moisture in the air. This further develops into a dry crust which may sink to the bottom of the container. If possible, this material should be separated and not used. Only the clear material can be relied upon to provide all the expected reactivity. Personnel should use gloves and eye protection and be provided with adequately ventilated surrounding.
