Barrier Coatings

Recent advances in coating technology and manufacturing has made it possible to apply barrier coatings on nearly any substrate. Whether you require coating on glass, ceramics, metal, plastic, fiberglass, polymers, leather, or cloth, chances are it is possible to apply a barrier coating that meets your needs.

Examples of different types barrier coatings include creating moisture barrier, gas barrier, chemical barrier, UV barrier, and thermal barrier.

The property of the barrier coating material has to be matched with that of the underlying substrate. The challenge is to find a way to chemically/physically bond the topcoat to the substrate. Because of the diversity of barrier coatings available there are several methods of applying these coatings to a substrate. The method of application is chosen based on the coating material characteristics as well as the substrate material, finish requirement and application convenience.

The application process most commonly used is wet spray, dip application is also used. Some specialty barrier coatings are applied through vapor deposition and others are plasma sprayed. Regardless of the application method, barrier coatings are chosen to meet specific needs and experts at FNG Precision Coatings are here to assist you in selecting the coating most appropriate for the intended purpose.

Here are some examples of barrier coatings:

Turbine Blades and Vanes

Turbine engine blades and vanes can operate at 1200C and beyond! The operating environment is hot enough to significantly diminish the strength of turbine blades and vanes. Without internal cooling and external thermal barrier coating, these parts would fail. Thermal barrier coatings in turbine engines typically start with a metallic bond-coat, then a thermally grown oxide layer (TGO) and an yttria-stabilized zirconia (YSZ) ceramic topcoat.

Textiles

Outerwear and textiles are coated with nanoparticles and polymers to improve the certain characteristics such as water proofing wind proofing, stain resistance and antimicrobial. There are also coatings that provide superior characteristics such as flame retardant, thermo-chromic, super-hydrophillic, EMI shielding, heat conduction, photochromic and self-healing.
