The classic full-shade chrome yellow — for industrial/export use

Middle Chrome is the classic full-shade chrome yellow — richer and warmer than the lemon grade, delivering the deep, saturated yellow associated with industrial and traffic applications, with exceptional hiding power and outstanding acid, alkali, and solvent resistance. As a lead chromate pigment it is intended for industrial and export markets; it is restricted or prohibited in many consumer and toy applications. Always verify compliance with applicable regulations in your destination market before use.
