Eliminate the Stickiness of Silicone Rubber with Slick Sil® LSR

Surface Solutions Group has developed a totally conformable yet flexible and low friction Slick Sil® LSR coating for silicone rubber that is bonded chemically to the silicone substrate. Slick Sil® LSR is a replacement for parylene, which is a physical bond and tends to crack and peel when the substrate is flexed or stretched. This dramatic low friction coating Slick Sil® for silicone rubber allows designers and engineers to have the benefits of silicone rubber without the high friction surface.

All molded or extruded silicone rubber components can be processed with the SSG Slick Sil® LSR low friction technology. SSG’s Slick Sil® LSR is a great parylene replacement coating that makes silicone slippery.

Low Friction & Flexible Replacement for Parylene

Slick Sil® LSR is a translucent matte coating designed to reduce the coefficient of friction (CofF) and hence, the friction force of molded and extruded silicone elastomers. The ability of Slick Sil® LSR coatings to reduce the surface friction of elastomeric silicone parts enables LIM® (Liquid Silicone Rubber), HCR, and RTV materials to be used in areas that were previously closed to silicones due to their high inherent CofF.

Key Features

  • Low friction (.31) vs. raw silicone (.65)
  • Chemical bond
  • Thin film (.0005” – .001”)
  • Elastomeric
  • Excellent elongation
  • Reduces surface dust pick up
  • VOC (Volatile Organic Compound) free
  • Biocompatible (USP class VI requirements)
  • Can be tinted by using silicone compatible pigments
  • Anti-microbial properties (optional)

Disadvantages of Parylene & Silicone Lubricants


  • A rigid coating that cracks on flexible silicone (physical bond)
  • Requires time-consuming and expensive vapor deposition process
  • No anti-microbial properties

Silicone Lubricants

  • If not applied correctly, the lubricant can migrate
  • Extra cost and step in manufacturing process
  • Contamination of other manufacturing areas in facility
  • Extremely expensive
  • No anti-microbial properties
