The support of a passionate team of experts with over 100 years of cumulative experience in the medical device sector.

Routine Coating services

Routine coating of your products/components in an ESD safe, class 5 cleanroom environment including:

• Proprietary surface preparation techniques

• Masking/demasking options

• Downstream subassembly steps (upon request)

Full traceability in compliance with ISO13485 requirements.

Relevant Lab Testing 

Routine testing of your feasibility, industrialization and production batches per our quality management system (QMS).

Verification and validation testing to support you in meeting ISO and FDA requirements.

Dedicated performance test methods such as:

• Adhesion testing

• Helium diffusion testing

• Thickness measurements

• Accelerated aging

• Surface insulation resistance (SIR)

• Bending test

10 microns multilayer provides same protection as 2 cm Epoxy layer or 60 cm silicone layer

Technology Platform 

Our coating platform typically combines organic and inorganic layers deposited at ambient temperature via a modified proprietary Chemical Vapor Deposition (CVD) process.

Our single-chamber CVD reactor allows a 3D conformal deposition of Parylene, ceramic or combined Parylene/ceramic multilayers on a variety of substrates and complex geometries.

The proprietary design of our third generation of reactors offers a tight control of the coating’s thickness as well as full flexibility of the layer combinations.

Using our multilayer as a super-flexible super-thin printed circuit board offers exciting perspectives for smart foldable devices.

Coat-X’s novel technology can replace conventional and expensive metal, glass or polymer encapsulation/protection solutions.

It can be used for many different applications such as: barrier protection for implants and wearables PCBs, encapsulation of corrosion sensitive micromagnets, protection and electrical insulation of instruments…

The technology can be tailored to your application, providing a variety of potential benefits such as:

  • Biocompatibility
  • Superior corrosion and humidity resistance
  • Excellent electrical insulation
  • Very low coefficient of friction
  • Ultrathin conformal chemically inert interface
