Advantage of Slick SilŪ on Silicone for Medical Devices
Silicone is a perfect biomedical material, except for one fault, it is too tacky for most applications. When silicone rubber comes in contact with other surfaces including other silicone it will resist motion with a coefficient of friction that exceeds 1.0.
Some solutions that have been used in the past are a thin dry coating like Parylene. Two major issues with Parylene is that it does not flex or bend with the silicone substrate, the other is that the Parylene can actually change the durometer of the silicone making it much harder than desired. Silicone oils, and other lubricants have been used on silicone but have limitations. While the oils are highly effective at lubricating the silicone, they tend to migrate away from the silicone surface and end up all over your device or work area, and the cost of these oils and lubricants that are approved by the FDA are extremely expensive.
A few years ago, Surface Solutions Group had introduced a new solution to the tackiness problem of silicone, it's called Slick Sil®. Slick Sil® is a translucent coating that chemically bonds with silicone rubber and reduces the coefficient of friction by 30% sometimes more. Because of the chemical bond to the silicone, Slick Sil® will elongate, bend and flex with the substrate without the flaking and cracking that you may have experienced with using Parylene, and with it adhering to the silicone substrate you do not have to worry about it migrating away for the surfaces that need to be lubricated. This makes Slick Sil® an ideal addition to any silicone rubber that needs to be slippery.
Slick Sil® is a unique coating in that it can be applied to many different types of silicone, and to many different durometers of silicone It also has an advantage over Parylene as it does not need to be applied in a vacuum deposition chamber, it can be sprayed, dipped, or even brushed on to the silicone substrate. Another advantage of Slick Sil is it can be infused with antimicrobial agents and has a kill rate of 99.9% for a long list of common bio-pathogens but have extremely low toxicity to people.
