Abstract
Polyamide coating compositions that demonstrate strength and toughness, flame and corrosion resistance and resistance to hydrolysis and thermal degradation at coating thicknesses of less than or equal to 0.25 mm or 0.15 mm are provided. Such coating compositions are extremely useful for coating wires or cables that are housed in automotive electrical harnesses.
Claims20
