Corrosion Resistant Coating Solutions

Extend Product Life, Prevent Contamination

Improve Performance and Reliability while Reducing Costs

SilcoTek corrosion resistant barrier coatings prevent flow path surface interaction with reactive chemicals, extending component life while preventing product contamination. Our customers use corrosion resistant CVD coatings like Silcolloy® 2000, Siltride® 1000, and Dursan® on stainless steel as a cost-effective replacement for exotic alloys. SilcoTek coatings are especially effective for fighting corrosion in high purity and sensitive processes in semiconductor, pharmaceutical, energy, and other complex chemistry applications. In addition to extending the usable life of stainless steel parts, SilcoTek coatings prevent nano-scale corrosive reactions that cause metal ion leaching and contamination. SilcoTek coatings help you and your customers achieve higher process up-time, yields, and overall value from critical processes.

Solvent - Metal Leaching

Metal ion leaching is invisible to the naked eye but a common issue, even when dealing with mild solvents. With SilcoTek CVD coatings, you can expect: 

  • Significantly longer usable life of stainless steel equipment
  • Reduced contamination and maintenance of chromatography systems 
  • Metal-free analytical flow paths
  • Prevention of metal ions leaching into process and sample fluids
See The Data

ICP-MS Data shows that Dursan and Siltride-coated frits experienced less leaching when exposed to methanol for 1 month.

Salt Spray

SilcoTek's coatings perform exceptionally well in salt spray exposure. Using our coatings, you can: 

  • Replace expensive exotic alloys
  • Preserve sample integrity 
  • Reduce downtime 
  • Lower maintenance costs 
See The Data
Both Silcolloy 1000 (middle) and Dursan (right) performed exceptionally well after enduring 8,064 hours of salt spray exposure! 4 weeks of pH-neutral salt spray (NaCl), then 4,032 hours of acidified salt spray per ASTM G85-A2.

Hydrochloric Acid 

SilcoTek coatings protect against hydrochloric and other aggressive acid damage to improve system performance and value.

  • Barrier coatings block HCl acid corrosion, pitting, and staining of base metals
  • Preserves the integrity of sample and process media
  • Outlasts uncoated equipment
  • Less expensive than exotic alloys, like Hastelloy®
See The Data

Passivated Dursan, Silcolloy 2000, and Siltride 1000 were compared to uncoated 316L stainless steel. The passivated Siltride resisted 5% HCl corrosion at a rate of 0.0012 mpy! Dursan and Silcolloy were closely following.

5% HCl, Room Temp, Pass

18.5% HCl is highly corrosive no matter what environment you're in. We compared Dursan, Silcolloy 2000, and Siltride with uncoated 316L stainless steel. The Siltride-coated sample outperformed the uncoated sample by more than 4,000%!

Fluorinated Gases

SilcoTek coatings protect equipment such as exhaust abatement systems from aggressive fluorinated gases and corrosive byproducts.

  • Resists NF3 and other fluorinated gases
  • Extends system life
  • Avoid frequent equipment replacement 
  • Significant reduction in heavy metal waste
See The Data

The mass loss graph below shows that over the course of 252 days in an exhaust scrubber, 3 control parts (red-dash line) failed during the test period with over 40% mass loss, while the Siltride-coated part (blue line) remained structurally sound with less than 2% mass loss.
