Metal Finishing Industry

Metal and 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

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.
Many metals are structurally weakened by the oxidation process, but not aluminum. Aluminum is actually made stronger and more durable through anodizing. Anodizing provides corrosion protection, decorative surfaces, and can provide electrical and mechanical properties. Pacifica specializes in the chemistry and technical support for sulfuric acid, chromic acid, hard coat and PTFE (Teflon) anodizing. (Our Anodizing chemistry meets Mil Specs MIL-A-8625 and MIL-A-63576, types I, II and III. )

Alkaline/Acid Pre-cleaning

Cleaning is the most important phase of metal working, fabricating and finishing. A clean surface is the critical foundation for subsequent operations.  Alkaline cleaning is the mainstay of industrial cleaning. Cleaners are many in number and vary in type and formulation.  Working solutions of alkaline cleaners may employ both physical and chemical actions. Proprietary alkaline cleaners are specifically formulated chemical blends.  These products typically consist of alkaline builder salts, surfactants, emulsifiers and chelators.The correct cleaner is determined by consideration of a number of factors.  First, it is necessary to determine the base metal undergoing the cleaning process.  This is the most critical step to assure that the alkaline builders chosen will not attack the basis metal.  Soft metals such as aluminum, zinc and zinc alloys such as brass require a milder (lower pH) cleaning solution.

Military, Aerospace & Decorative Plating markets

We strive to use Lead and Cadmium free chemistry during during the entire course from Pretreatment and Plating, and Post treatment stages.

Brighteners

Levellers

Rust & Tarnish Preservatives

Zincates

Chromates

Anti-Pitting Agents

Nickel Strike Chemistry

We carry liquids and powders that can either emulsify or split out soils once removed ACIDIC CLEANING is used for the removal of primarily inorganic soils from hard surface substrates. These soils include rust, oxides, scale and mineral deposits and are also applied though an immersion or spray application. There are many types of acids in our product line available.
