Metal Finishing


Metal finishing involves a broad range of processes that are practiced by most industries which manufacture metal parts. Finishing, typically done after completion of a part, can be any operation that alters the surface of a work-piece to achieve a certain property.

PCI produces a number of performance chemicals for the industrial treatment of metal surfaces. Our range of products are deployed across the entire process chain from pre treatment to post treatment.

Pacifica carries the complete line of chemistry which is used in the following surface finishing processes:

  • Corrosion resistance
  • Hardness
  • Wear resistance
  • Thermal conductivity
  • Appearance Improvement


Anodizing represents an electrochemical technique that transforms the surface of a metal into an enduring, aesthetically pleasing, and corrosion-resistant anodic oxide finish. While aluminum is the most suitable candidate for anodizing, other nonferrous metals like magnesium and titanium can also undergo this process.

Contrary to many metals that experience structural weakening due to oxidation, aluminum actually gains strength and durability through anodization. This process not only furnishes protection against corrosion but also imparts decorative attributes, along with the potential for enhanced electrical and mechanical characteristics. Within this realm, Pacifica specializes in formulating and offering technical support for an array of anodizing techniques, including sulfuric acid, chromic acid, hard coat, and PTFE (Teflon) anodizing. (It is noteworthy that our Anodizing chemistry adheres to the stringent Mil Specs MIL-A-8625 and MIL-A-63576, encompassing types I, II, and III.)

Alkaline/Acid Pre-cleaning

Effective cleaning plays a vital role in metal working, fabricating, and finishing. A surface that's thoroughly cleaned sets the important groundwork for all the next steps. When it comes to industrial cleaning, alkaline cleaning is the go-to method. There are various types of cleaning products available, each with different ingredients and formulas. Alkaline cleaners, specifically designed chemical blends, are commonly used. These cleaners usually contain alkaline builder salts, surfactants, emulsifiers, and chelators.

Choosing the right cleaner involves considering a few important factors. Firstly, it's crucial to identify the type of metal being cleaned. This step is really important to make sure that the chosen alkaline cleaner won't harm the metal. For softer metals like aluminum, zinc, and zinc alloys like brass, a gentler cleaning solution with a lower pH is needed to avoid any damage.

Military, Aerospace and Decorative Plating Markets

We strive to use Lead and Cadmium free chemistry during during the entire course from Pre-treatment and Plating, and Post treatment stages.  Some of our products include:



Rust & Tarnish Preservatives



Anti-Pitting Agents

Nickel Strike Chemistry

In our inventory, we offer both liquid and powder solutions that have the ability to either break down or separate dirt and grime when ACIDIC CLEANING is employed. ACIDIC CLEANING is particularly effective for eliminating mainly inorganic dirt from solid surfaces. This type of grime comprises elements like rust, oxides, scale, and mineral deposits. The process involves immersing or spraying the affected area. Our product range includes a variety of acid options tailored for different needs.
