Sun Chemical: The polymer-encapsulated aluminum pigments are designed for single-coat applications that require a high level of acid and base resistance or non-conductivity. An expansion of the SunMetallics® aluminum pigment product line, these pigments maintain the brilliance and gloss of the base pigments while resisting tarnishing in areas that are exposed to acidic or basic materials. The polymer encapsulation makes the pigments less conductive, which is essential for the consumer electronics market.
