Silicone Lubricant And Sealant MOLYKOTE 111 For Valves / Pressure Systems

MOLYKOTE 111 Silicone Lubricant and Sealant for Valves, Pressure Systems

Product Properties

Molykote 111 is a silicone-based compound thickened with inorganic agents. It features a broad service temperature range (-40°C to 200°C), excellent water resistance, low vapor pressure, and low volatility, complying with global standards including NSF 51/61 and FDA 21 CFR 175.300 for water contact.

Product Introduction

MOLYKOTE 111 Compound is a silicone-based lubricant and sealant formulated with silicone oil and an inorganic thickener. It offers a wide service temperature range of -40°C to 204°C, excellent water resistance, and compatibility with numerous plastics and elastomers. The compound has low vapor pressure and volatility, and it contains no intentional PTFE or PFAS additives, meeting global standards for water contact such as NSF 51, NSF 61, and FDA 21 CFR 175.300.

Enhanced Properties

The special properties of MOLYKOTE 111 Compound enhance its reliability in demanding environments. Its low bleed and evaporation rates (0.2% and 0.8% respectively at 204°C per AMS8660) ensure minimal loss under high-temperature conditions, while the volume change of -0.4% with rubber indicates minimal swelling or shrinkage. Electrical characteristics, including a dielectric strength of 320 volts/mil and high volume resistivity (up to 1.09×10¹⁴ ohm-cm at 23°C), make it suitable for electrical and electronic applications. Additionally, its thermal conductivity of 0.248 W/mK at 30°C supports use in heat dissipation scenarios, and the compound's resistance to dilute acids, alkalines, and aqueous solutions per TDS chemical resistance section adds to its versatility.

Application Scenarios

MOLYKOTE 111 Compound is primarily used for lubrication in control valves, pressure plug valves, water softener valves, and faucet valves. It serves as a sealant for vacuum and pressure systems, outdoor equipment exposed to washing and harsh environments (e.g., shipboard meters and underground connections), and as a damping medium in electrical dash pots. Specific applications include anti-stick and sealing for transformer gaskets, preventing weathering and water washout. Online sources, such as DuPont's product page, confirm its use in food and beverage processing equipment due to NSF and FDA certifications for potable water contact, though no new unique data was found beyond TDS.
