The Novagard G641 is a 5 oz. tube of silicone heat sink grease compound that provides thermal conductivity, a high dielectric constant, and a long shelf-life for use in electric and electronic applications such as thermocouple wells, power diodes, transistors, semiconductors, and ballasts. The compound is formulated with polydimethyl siloxane fluids with metallic oxide fillers. It has a temperature range of -60 to +400 degrees F (-51 to 204 degrees C). The compound resists oil separation and has a white paste consistency.

Industrial lubricants can be found in most machinery performing one or more functions, including reducing friction and wear, preventing components from adhering to each other, distributing loads more evenly, dispersing heat away from moving parts, and preventing corrosion. Although many materials are used as lubricants, the most common are oil (also called fluid lubricants) and grease because of their versatility. Oil lubricants contain either a petroleum or synthetic base, the properties of which are modified by the addition of various additives. Grease lubricants, a mixture of oil lubricant and a thickening agent, have a thicker consistency than oil, enabling use wherever liquids cannot be retained and requiring less frequent changes.

Novagard Solutions manufactures industrial adhesives, sealants, and lubricants. The company, founded in 1977, is headquartered in Cleveland, OH.
