Extrusion coater" means an apparatus in which a coating material is applied by means of a slotted die to a moving substrate, which is fed from an unwinding roll.
Specialty coating means any coating that is manufactured and used for one (1) of the following specialized applications:
Basecoat means a coat of colored material, usually opaque, that is applied before graining inks, glazing coats, or other opaque finishing materials and is usually topcoated for protection.
Hood means a respiratory inlet covering that completely covers the head and neck and may also cover portions of the shoulders and torso.
Clear coating means a transparent coating designed to provide the final gloss and resistance properties of the coating system;
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Nuclear coating means any protective coating used to seal porous surfaces, such as steel or concrete, that otherwise would be subject to intrusion by radioactive materials. These coatings must be resistant to long term (service life) cumulative radiation exposure (ASTM D4082-83**), relatively easy to decontaminate (ASTM D4256-83**), and resistant to various chemicals to which the coatings are likely to be exposed (ASTM 3912-80**). General protective requirements are outlined by the Department of Energy (formerly United States Atomic Energy Commission Regulatory Guide 1.54**).
Pretreatment coating means a coating which contains no more than 12% solids by weight, and at least 0.5% acid by weight, is used to provide surface etching, and is applied directly to metal surfaces to provide corrosion resistance, adhesion, and ease of stripping.
