Astro Pak has over 50 years of experience in perfecting Passivation & Precision cleaning. Our wealth of experience and understanding of stainless steel surface chemistry led us to develop, Ultra Pass®, our proprietary passivation chemistry and process for stainless steel that produces an optimized passive layer on the surface of stainless steels.

We have cleaned and passivized parts and components for almost every cleanliness-critical industries and applications. Our extensive library of specifications and procedures enables us to meet any customer or end user requirements. Our dedicated and qualified staff of chemists, technicians and engineers evaluate components and determine the proper chemistry and method of cleaning to achieve cleanliness requirements.

Our CA facility is the largest if its kind, boasting state of the art ISO 9001:2008/AS9100 Certified Class 5 (class 100) and Class 6 (Class 1000) cleanrooms that are controlled and monitored.
