Pigmentation Study of NARPOL Primer,

摘要

The work was concerned with attempts to optimize the formulations of NARPOL thermally stable aircraft coatings. NARPOL is a partially fluorinated polyphenyl ester polymer. The NARPOL coatings exhibit most of the requisite qualities of a high temperature (500F) resistant aircraft coating system except for sufficient adhesion to aircraft metals. The report covers the further evaluation of the most promising aluminum hydroxide pigmented primer along with other attempts to upgrade the adhesion of the NARPOL coating system by changes in the pigmentation. Variations in pigmentation of the NARPOL primer has not resulted in any improvement in the adhesion of the NARPOL coating system. However,the use of camouflage topcoats instead of gloss,combined with a bake cycle improve the adhesion of the NARPOL coating system. (Author)
