Most motor factory used insulating paint volatile acid composition mainly has four kinds:

No reactions of low molecular paint raw acid composition ( anhydrous isopropyl neighbor and terephthalic acid, anhydrous maleic acid, fumaric acid ).

The paint curing is generated when the acid composition ( with phenolic paint, by formaldehyde water into formic acid ).

The heat or oxidative decomposition of fatty acids ( formic acid, acetic acid ).

The paint curing water decomposition generated acid composition. Insulating paint the main component of acid is formic acid, formic acid amount and corrosion degree there is a close relationship between the.
