Cabosil M-5 LD Silica (1 Gallon)

• For a shiny finish
• 1 Gallon

CAB-O-SIL M-5 untreated fumed silica is a synthetic, amorphous, colloidal silicon dioxide that is generally regarded as unique in industry because of its unusual particle characteristics. CAB-O-SIL fumed silica’s extremely small particle size, its enormous surface area, its high purity, and its chain-forming tendencies set it apart in a class of its own. CAB-O-SIL fumed silica is a light, fluffy powder that is white in appearance and is used in many applications and a variety of industries.

CAB-O-SIL M-5 is a medium surface fumed silica which imparts significant increase in viscosity in liquid systems, free flow of powders and reinforcement of silicone and organic rubbers.

All untreated fumed silicas are characterized by:

• High purity
• Aggregated structure
• Submicron particle size
• Low bulk density
• Hydrophilic surface

Application Information

Rheology Control for Coatings, Adhesive and other Liquid Systems:
CAB-O-SIL M-5 is widely used to provide thickening, thixotrophic (shearthinning), and anti-settling behavior in liquid systems. M-5 is most efficient in non-polar to medium polarity systems. For more polar systems, treated fumed silicas are more ffective. M-5 offers the best balance of thickening efficiency and dispersibility.

Free-flow of Powder Systems:
When blended into sticky and poorly flowing powder systems, M-5 reduces angle of repose and improves powder flow. During storage of powder systems, M-5 reduces caking and blocking.

Reinforcement of Silicone and Organic Rubber:
CAB-O-SIL M-5 can be used for reinforcement of silicone rubber and can be used to reinforce organic rubbers. It imparts good increase in hardness, tensile and elongation.
