Here's what our customers say about our coatings:

"So often you get bounced to and from departments that you forget why you were calling. Not the case with you guys, you made us feel you were with us all throughout the project. I would not hesitate to recommend SilcoTek and your amazing team."

SilcoTek Coatings Optimize Performance

Extrusion and injection mold machines can benefit from precision CVD coatings to prevent damage to molds or extruders.  Outgassing, moisture acidity, and abrasive wear can take their toll on mold quality and result in costly replacement or repair.  SilcoTek® coatings offer greater wear resistance while reducing friction and improving corrosion resistance.

SilcoTek Coating benefits:

Even under extreme pressure and temperature, SilcoTek® coatings significantly improve mold release and corrosion resistance. Coating benefits include:

  • 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.
  • Prevents contamination by oxidation by products in medical and electronic applications.
  • A change in our luminescent release agent rainbow finish signals a loss of coating.  Visual inspection of the surface signals coating loss without precision measurement. 
  • Mold complexity does not significantly impact coating price. 
  • Eliminate Diamond finish release problems by improving surface lubricity.   

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 surface improves lubricity by 36% over stainless steel while reducing surface energy by up to 8x.
