Non Stick and Release Coating Properties

Improve Product Quality and Efficiency

SilcoTek® Non Stick Coatings Improve Productivity and Product Quality in Extrusion and Mold Release Applications 

SilcoTek coatings can improve efficiency and prevent damage to molds or extruders, while solving common material problems like corrosion and mold release.  Outgassing, moisture acidity, and abrasive wear take their toll on mold quality and result in costly replacement or repair. SilcoTek® coatings, like Dursan®, reduce friction and stiction while improving moisture and corrosion resistance. SilcoTek coatings bond to process surfaces and act as a non stick, hydrophobic barrier that improves surface performance.

Even under extreme pressure and temperature, SilcoTek® coatings significantly improve mold release and corrosion resistance , allowing more efficient and easy release of product from molds and extending the life of extruders and dies.  

Mold image 6.png Coating features and benefits include:

  • Low surface energy, high contact angle surface
  • Better wear resistance for higher durability, and erosion prevention.
  • Higher lubricity to improve operation of moving cores and slides and improved resin flow for reduced energy cost and wear.
  • Takes the Place of release chemicals
  • Prevent contamination by release chemicals and oxidation by-products in medical and electronic applications.
  • Change in our luminescent release agent rainbow finish signals a loss of coating.  Visual inspection of the surface signals coating loss without precision measurement. 
  • Does not transfer onto the plastic part during molding.  
  • Eliminate Diamond finish release problems by improving surface lubricity. 
  • Improved corrosion resistance of extruder and mold components.

Solve Release Problems

SilcoTek's patented silicon chemical vapor deposition (CVD) coating technology can be applied to complex or narrow part configurations without impacting even extremely tight tolerances.  Comparative studies show SilcoTek coatings outperform most materials commonly used in mold and extrusion applications.

Solve common extrusion and mold release problems:
  • Critical surface pitting due to corrosion
  • Poor release of product from mold
  • Product damage due to surface irregularities
  • Frequent extruder tool replacement
  • Mold damage

Our low surface energy (high contact angle) surface combined with a low coefficient of friction improve mold flow and release.  Comparative testing shows the Dursan® coated surfaces significantly improve hydrophobicity by reducing surface energy by up to 8x.  Surface energy water droplet testing below compares various coated surfaces.  Stainless steel, a high surface energy material, exhibits significant wetting and a very low water droplet contact angle (36 degrees), causing sticking and mold release problems.  The Dursan low energy surface shows minimal wetting and a high contact angle of 143 degrees, promoting better mold release.

 Comparative pin-on-disk wear and friction testing shows the Dursan® coated surface improves lubricity by 36% over uncoated stainless steel while reducing wear by over 50%.
