VISCOPLEX 14-520 is a high-performance, silicone-free defoamer designed for a wide range of lubricating oil applications. Developed by Evonik Industries , it utilizes patented Organo-Modified Siloxane (OMS) technology to manage foam while minimizing the air entrainment issues common with traditional silicone defoamers. Quick Facts Product Type: Silicone-free defoamer (OMS-based) Manufacturer: Evonik Industries Appearance: Clear liquid Treat Rate: Typically 200–400 ppm Solvent: Ester-based for easy handling Technical Overview Unlike classic polydimethylsiloxane (PDMS) defoamers, VISCOPLEX 14-520 focuses on air release properties. Traditional silicone oils effectively break surface foam but often trap air within the lubricant, leading to spongy hydraulic response and cavitation. Key Properties Value (Approx.) Active Ingredient Silicon Content 0.9% (w/w) Density (15°C) 0.93 g/cm³ Viscosity (25°C) Flash Point > 120°C (ASTM D 3278) Core Benefits Advanced Air Release: Reduces air entrainment to ensure consistent pressure and lubrication. Stable Performance: Maintains defoaming efficiency even after long-term storage or high-shear conditions. Easy Handling: Low viscosity allows for direct blending without the need for pre-dilution in most plant operations. Wide Compatibility: Effective across various base stocks, including engine oils, transmission fluids, and biodegradable lubricants. Primary Applications VISCOPLEX 14-520 is primarily used in high-performance fluid formulations where air entrainment is a critical concern. Automotive: Engine oils and transmission fluids (ATF, CVT) that require rapid air release for smooth gear shifting. Industrial: Hydraulic fluids and gear oils used in heavy machinery and construction equipment. Bio-Lubricants: Specialized for use in biodegradable fluids where traditional additives may not be compatible.

Viscoplex 14-520 is a high-performance anti-foam (defoamer) additive developed by Evonik Industries . Unlike traditional silicone-based defoamers, it is a soluble-type additive specifically engineered as a "problem solver" for oil-based lubricants where conventional products fail . Key Functions & Benefits Superior Foam Control: It provides excellent foam suppression and is highly effective at maintaining demulsion performance (separating oil from water) over long periods. Minimal Impact on Air Release: One of its primary advantages is that it helps meet air release targets with minimal impact on other lubricant properties, which is critical for systems prone to air entrainment. Siloxane Technology: It utilizes a siloxane backbone for high surface activity but is formulated as an 8% active ingredient dilution in an ester solvent to simplify blending and ensure a high flash point. Surface Compatibility: It is suitable for oils where accidental contact with surfaces might occur, such as those requiring subsequent overpainting, as it doesn't cause the same "fish-eye" issues as some silicones. Technical Specifications Typical Value Appearance Clear, yellow viscous liquid Active Ingredient Approx. 8% Silicon Content Approx. 0.9 (w/w)% Density (15°C) Approx. 0.93 g/cm³ Viscosity (25°C) Approx. 27 mm²/s Flash Point > 120°C (ASTM D 3278) Recommended Treat Rate 200–400 ppm (parts per million) Common Applications Viscoplex 14-520 is frequently used in industrial and automotive lubricant formulations where foam control is vital, including: Hydraulic Systems and circulating oils. Compressor Oils . Automotive Transmission Fluids . Biodegradable Fluids and engine oils. For detailed safety information, you can refer to the Evonik Safety Data Sheet which highlights that the material is generally stable but should be stored in well-ventilated areas away from extreme heat.
