Inner-Wall Coating on Narrow Tubing
A PTFE film of ~4.0 microns was coated on the inner wall of this tube, 1.3 m x 3.9 mm inner diameter). Coating penetrated entire length of tube. Variation in thickness with length can be controlled.

The chemical resistance, high purity, biocompatibility, thinness, smoothness and integrity of GVD coatings make them highly suitable for medical devices. Due to the flexibility of the process, GVD can coat practically any substrate, regardless of size, shape or material. GVD technology is suited for coating of fine wires, complex surfaces and inner surfaces of ultra-fine catheters.
