Although PTFE is an ideal lubricant for coating gun barrels, it is a difficult material to deliver, as the PTFE particles tend to settle out of a liquid carrier system. A proprietary blend of constituents was developed to prevent settling and buildup, so it is now possible to deliver PTFE micro-particles to the surface to be coated in a very uniform manner. Each particle is less than 0.0004 inches in diameter, which permits the particles to enter and fill the small imperfections in the microstructure of the bore. This results in a smoother bore, presenting a much lower friction coefficient to the bullet as it passes through. It also inhibits the buildup of lead and copper residues in the bore after firing.
Firearms cleaning is a much easier chore.
BORE COTE will outlast conventional gun lubricants. Petroleum distillates congeal and begin to polymerize immediately upon exposure to ultra-violet light. These coatings also stain clothing and holsters. When sprayed onto a surface, the product quickly dries to form a dry film that resists corrosion. A test plate coated with ARMS COTE withstood 216 hours of salt spray without showing evidence of corrosion.
