Introducing SurTec® 650 RTU ChromitAL TCP
(An Iridite or Alodine replacement)
RoHS Directive: Click here
We now supply RoHS Compliant
Aluminum Passivation
This finish is performed in accordance with MIL-DTL-5541F Type II Chromate Conversion Coating to meet the strict European RoHS Compliance Directive. The finished aluminum parts will look different than the traditional yellow or gold color you are used to seeing with chromate. The finished parts will appear clear to a very slight bluish tinge. Further details of this finish are described below.
- A superior Trivalent Chromium Passivation process for aluminum and its alloys.
- ChromitAL TCP, supplied by CST-SurTec Inc, provides excellent bare corrosion resistance on unpainted surfaces and enhances adhesion of organic coatings. Applications include plain and anodized aluminum.
