Aerospace Specialty Coating
Section 211.284 Aerospace Specialty Coating
"Aerospace
specialty coating" means a coating that, even though it meets the
definition of a primer, topcoat, or self-priming topcoat, has additional
performance criteria beyond those of primers, topcoats, and self-priming
topcoats for specific applications. These performance criteria may include,
but are not limited to, temperature or fire resistance, substrate
compatibility, antireflection, temporary protection or marking, sealing,
adhesively joining substrates, or enhanced corrosion protection. Aerospace
specialty coatings are listed in 35 Ill. Adm. Code 219.204(r)(2).
