For Transforming Surface Performance

When Reducing Friction Matters

Many medical and industrial applications require lubricious or non-stick surfaces that don’t react with the sensitive chemistries and materials contacting these surfaces. Traditional coating methods often fall short of these requirements, but not GVD’s PTFE lubricious and non-stick coating. Unlike conventional spray and liquid phase coating methods, GVD’s chemical vapor deposited PTFE is conformal in three dimensions with excellent thickness control, requires no solvent, is chemically inert, and is well-adhered to the coated surface.

Creates a Lubricious Surface

The PTFE coating process transforms surfaces to be non-stick, low friction and hydrophobic. A variety of materials can be coated, from flexible elastomers to rigid plastics and metal.

Applies Conformal & Ultra-Thin

GVD’s PTFE coatings are applied at 50 nanometers to 10 microns thick, transforming the surface with a conformal and ultra-thin membrane without pooling or degradation of surface texture.

Applies Dry & at Room Temperature

Unlike traditional spray-and-bake PTFE coatings, GVD’s PTFE coating is applied through a vacuum deposition process. The coating is formed in a dry, solvent-free environment, and there is no need to expose the coating and substrate to a high temperature post-bake.

Withstands High Temperatures & Corrosive Agents

GVD’s PTFE coating is chemically identical to bulk PTFE—it has all the benefits without the harsh processing required of traditional PTFE coatings.

PTFE FAQs

GVD’s PTFE coating is chemically identical to bulk PTFE, ploytetrafluouroethylene. PTFE is a widely-used polymer that has unique properties including lubricity, excellent release characteristics, high chemical resistance, and hydrophobicity.

Yes! PTFE has been used for years to reduce friction in food and medical device industries. Contact GVD for more information on application compatibility.

Typically most applications require 50 nm to 10 microns thick of coating on a substrate. GVD will work with you to determine the ideal thickness for each application.

GVD’s coating technology utilizes vacuum deposition techniques. Substrates must be vacuum compatible, meaning they will not outgas, shrink, or expand when exposed to a vacuum environment. GVD has proven their technology can scale-up, so please contact us even if your substrate is larger than the current size limit of 40”x40”x2”.

Yes. GVD’s coating is being used commercially for a wide variety of applications and industries, mainly as a lubricious coating for elastomers but other materials as well.

GVD has two plants where production coatings are completed. We’ve completed rapid scale-ups in the past which have included expanding resources, increasing number of coating machines, and/or increasing the size of coating machines. Contact GVD to discuss any high-running parts production requirements.

It depends on the application. GVD’s PTFE coating is a good release coating on metal substrates. It should not be used in applications that require significant mechanical abrasion, such as a sharp metal edge scraping the surface.

Most likely the answer is no. If attempting to coat inside a tube with an aspect ratio larger than 1:4, then GVD’s PTFE coating may not be best suited for the application. While the coating is conformal, it does not have good “throw” down long tubes.

It depends on the substrate and application. GVD’s coating can be IR transparent or it can have a hazy appearance at high thicknesses.

No. GVD’s coating, even though it is chemically resistant, should not be used as a chemical barrier layer.

Yes!
