Precision cleaning and deposition solvent technology for today's world

Growing public concern about the effects of chemicals on human health, safety and the environment have led to restrictions on the use of many kinds of process solvents used by the medical device industry for precision cleaning and coating deposition. In evaluating alternatives, users of these materials must balance the need for cost-effective performance with that of a sustainable, long-term solution – a solution that will still be viable for many years to come.

3M™ Novec™ Engineered Fluids were designed to help you achieve that balance. Based on 3M's proprietary segregated hydrofluoroether (HFE) chemistry, Novec fluids combine proven performance with an outstanding environmental and safety profile:

  • Zero ozone depletion potential
  • Low global warming potential
  • Non-flammable
  • Low in toxicity
  • HAPs-free
  • U.S. EPA SNAP-approved

Because of these favorable properties, Novec fluids have been accepted by regulatory agencies around the world as alternatives to ozone-depleting substances such as HCFCs – and they are ideal candidates to replace process solvents targeted for phaseout, including trichlorethylene, methylene chloride and n-propylbromide (nPb).

3M™ Novec™ Engineered Fluids offer a number of advantages for manufacturers of medical devices and equipment. They have demonstrated excellent compatibility with sensitive materials such as acrylic and polycarbonate, as well as a wide range of other plastics, elastomers and metals. Their low surface tension, low vapor diffusion rates and high liquid densities make Novec fluids ideal for use in vapor degreasing equipment. They are fastdrying, and typically offer lower drag-out losses than conventional degreasing solvents.

What's more, Novec fluids easily penetrate tight spaces on complex parts, then drain off easily so they don’t become trapped in small spaces. Compared to aqueous cleaning, therefore, Novec fluids increase confidence in the ability to validate a process free of bioburden, and are less equipment- and energy-intensive. In addition, parts cleaned in Novec fluids dry quickly and spot-free, with less chance for corrosion.

The versatile process solvent solution

Novec fluids are available in "neat" form – for light duty precision cleaning and contaminant removal. They are also available as azeotropes, which offer higher solvency for more difficult-to-remove soils. Novec azeotropes are used for tube swelling, lubricant and coating deposition, and other applications. Novec fluids are also used as rinsing agents in conjunction with low volatility solvating agents. This co-solvent cleaning process is effective for removal of the most challenging soils, such as heavy oils, greases, buffing compounds, waxes pitches, and high temperature solder pastes.

Medical Device Applications

Lubricant and Coating Deposition

Novec fluids offer you a safe, effective, sustainable solution as deposition solvents for a wide variety of coatings and lubricants – including silicone, fluorocarbons, PTFE and heparin. These nonflammable, fast drying solvents can be used for lubricant and coating deposition on many different types of surfaces, including metals, plastics and elastomers.

Precision Cleaning

The low surface tension, low vapor diffusion rates and high liquid densities of Novec fluids make them ideal for use in vapor degreasing equipment. They are fast-drying, and typically offer lower drag-out losses than conventional degreasing solvents. What's more, Novec fluids easily penetrate tight spaces on complex parts, then drain off easily so they don’t become trapped in small spaces. They have proven to completely evaporate from the surfaces making them ideal for cleaning medical devices.

3M EMSD Medical Device Policy

3M™ Novec™ Engineered Fluids are intended for use as process solvents in applications, such as cleaning and coating, that historically used CFCs and HCFCs. They are not intended, nor approved, for incorporation into medical devices or for use in pharmaceuticals. 3M will not support applications such as lung perfusion or blood substitutes, that involve temporary or permanent implantation of the Novec engineered fluid.
