Corrosion Resistant Coating Properties

Extend Product Life, Prevent Contamination

SilcoTek® Corrosion Resistant Coatings Improve Product Reliability and Reduce Cost

SilcoTek corrosion resistant barrier coatings prevent flow path surface interaction with corrosives; extending component life while preventing product contamination.  Our corrosion resistant coatings, Silcolloy®, Dursox® and Dursan®, are particularly useful for fighting corrosion in high purity or otherwise sensitive processes in semiconductor, pharmaceutical, research, and complex chemistry applications.  In addition to extending the usable life of precision stainless steel parts, SilcoTek coatings even prevent nano-scale corrosive reactions that can cause metal ion leaching and contamination, ultimately increasing process yield and reducing failure rates.

Solve Difficult Corrosion Problems

SilcoTek coatings help to prevent common corrosion related problems including:

  • Frequent component replacement
  • Process or product contamination problems
  • High maintenance costs
  • Sample probe damage and failure
  • Lost productivity due to excessive downtime

ASTM immersion testing proves SilcoTek® coated stainless steel enhances corrosion resistance by orders of magnitude, matching the performance of super alloys in many applications. Even after immersion in concentrated hydrochloric acid (below) the Dursan and Silcolloy coated stainless steel coupons continue to perform with minimal corrosion, demonstrating performance comparable to super alloys. 


SilcoTek coatings perform in a variety of corrosive environments including sulfuric acid and bleach.
