Kynar Coating

Kynar series coatings are used to form a “polymer barrier” which is 20 to 30 mils. thick.  This protective coating is typically used to line chemical processing industry (CPI) vessels.  It is specified because of its unique properties: unaffected by most chemicals and solvents, abrasion resistance, mechanical strength, and toughness.  Examples of other industrial operations which utilize Kynar include: acid etching associated with the manufacture of electronic components; bleaching operations in pulp & paper mills; and corrosion protection of valves, pipes and fittings found in insecticide manufacturing facilities.

Less well known properties of Kynar are its high thermal stability (no weight loss at 250ºC), ability to self-extinguish (will not burn in air), high dielectric strength (950 volts per mil), and excellent resistance to weathering, ultraviolet (UV) rays, and nuclear radiation.  These properties suggest that Kynar’s use in applications such as electrical insulation, protection of architectural/structural members, and water treatment equipment located in nuclear power stations.
