Aluminium stearate (also aluminum stearate) is a fine white powder which can be used primarily as an effective defoamer in many types of water-based drilling fluid systems. It is non-water soluble surface-active antifoam agent and can reduce surface tension. Aluminium stearate is effective at low concentrations by minimizing the foaming tendency of the drilling mud. Bichain is a reliable and professional defoamer manufacturer of aluminium stearate and aluminum stearate as mud defoamers and antifoaming agents in oilwell drilling mud and hydraulic fracturing.
Molecular formula: C18H35LiO2
CAS No.: 637-12-7
♦Effective in low concentrations 
♦Less effect on drilling mud properties
♦Can be used in most water based fluids 
Technical Data:
Aluminium aluminum stearate
Recommended dosage 
Aluminum stearate is not water soluble and must be mixed with glycol, diesel or alcohol before adding it to the drilling mud. In brine drilling fluids, its effectiveness will decrease. High polymer concentrations in drilling fluid systems also affect its effectiveness.
Normally, 15-30 Kg/m3 of mud can give adequate defoaming results.
Package and Storage
Package: 25Kg net weight WPP or PE bags or packed according to the clients' requirements. Store in dry cool and ventilation environment. Avoid moisture and damp. Don't pile up in the open air.
