To enhance chemical resistance

Inter-Ion  has been validated for Vacuum autoclaving of Nylon coated medical parts.
Inter-Ion applies nylon coatings to medical devices and a wide range of other industrial parts. Temperatures range from -60 C to 150 C and can be autoclaved in medical applications. Nylon coatings can adhere to practically any material: most metals, including steel, aluminum, copper.

Nylon properties:

  Excellent chemical and corrosion resistance
  Impact resistant
  High abrasion resistance with a very smooth finish
  High Wear Resistance
  High mechanical strength and elasticity, even at low temperature
  Low coefficient of sliding friction in dry motion contact with metals and other polymer materials
  Very good resistance to fats, oils, fuels, hydraulic fluids, saline solutions & many other organic solvents
  Good dielectric strength
  FDA approved


Complies with FDA regulations

Nonstick and abrasion resistance properties ideal for vessels used in pharmaceutical and biotechnology manufacturing, providing clean ability, durability and low maintenance cost


Xylan  is  a complete line of fluoropolymer coatings.

Xylan® Coatings are designed for use on machined components and fasteners to prevent corrosion and facilitate makeup torque.

Xylan/PTFE coating on Bolts, Studs & Nuts provides an ideal protection in corrosive environments, salt water conditions specially where lubrication is needed.


These coatings have excellent  properties:

  Nonstick - Very few solid substances will permanently adhere to a PTFE coated finish. Although tacky materials may show some adhesion, almost all substances release easily.
  Low coefficient of friction - The coefficient of friction of PTFE is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular Teflon® coating used.
  Nonwetting - Since surfaces coated with PTFE are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough - in many cases, surfaces are self-cleaning.
  Heat resistance - PTFE industrial coatings can operate continuously at temperatures up to  500F.
  Unique electrical properties - Over a wide range of frequencies, PTFE has high electric strength, low dissipation factor, and very high surface resistivity.
  Chemical resistance - PTFE is normally unaffected by chemical environments.
  Cryogenic stability - Many PTFE industrial coatings withstand severe temperature extremes without loss of physical properties. PTFE industrial coatings  can function between   -450F to +500F.

These coatings are very effective against bacteria, as well as a wide array of fungal organisms.

Suitable for Class I - III medical devices


Halar® / ECTFE coatings have a unique combination of properties with excellent chemical resistance, good electrical properties, a broad-use temperature range, outstanding abrasion resistance, and excellent impact strength.

Halar® / ECTFE Coatings resist a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics making them ideal for vessels and process equipment for many industries including the chemical and petrochemical  industry.


Kynar coating is primarily used on chemical processing equipment due to excellent chemical  resistance, excellent wear and abrasion  resistance and heat tolerance.

Kynar coatings have excellent resistance to weathering and can withstand harsh environments  while maintaining high dielectric strenghth and Kynar coating are especially resistant to solvents, acids and heat.


PEEK polymer is regarded as one of the highest performing materials in the world.
PEEK provides a unique combination of properties including mechanical strength and high temperature performance.

Benefits of PEEK polymer:

  Excellent strength, stiffness and dimensional stability in high temperature and harsh environments
  Low coefficient of friction and high wear resistance without lubrication
  Chemically resistant and insoluble in common solvents including acids, salts and oil
  Features low outgassing, low particle generation and inherent purity for reduced contamination
  Delivering extended high temperature performance

We have developed some novel applications in coatings, specifically in powder coating. For example, we have developed our own formula to apply powder coating to non-metals, such as wood. These types of know-how's set us apart from the rest. Examples include:

Powder Coating on Non-metals
Wood, ceramic, glass, fibergalss
Lead Replacement for X-ray Blocking
Inter-Ion has developed the process and application technology to replace lead based coatings that traditionally have been used in X-ray blocking areas.

Sequence of Coating System
Depending on the requirements for the final finish and the condition of the un-processed parts as they arrive, the parts would go through the following sequence of processes:



Surface Preparation
Surface preparation capabilites include:
Other surface conversion
Application techniques include:
Electrostatic and Fluidized Bed Coatings
Dip Coatings
Conventional Spray Coatings

Powder coating is usually applied by electrostatically charging the dry particles and blowing them on to a grounded part. A second powder technique is fluidized bed method, which may be recommended depending on your part and the coating you select.

Each individual part's geometry is analyzed in order to determine the appropriate method of curing/fusing for that application. The curing and fusing methods fall into two basic categories, namely infrared and convection. Gas fired, electrical, and/or infrared ovens are incorporated in order to induce curing/fusing.
