However, these impacts have moderated as of late.

Importantly these advances also now allow color to be combined with additional functional additives without impacting process stability. At four global ColorWorks centers, teams of experts work to establish high-impact color concepts at the earliest stages of product development to help you heighten shelf impact, differentiate brands, control costs and time- to-market, and manage color across multiple resins all around the world. Some key questions to consider when implementing liquid color: • Is your colorant addition negatively impacting or enhancing your process efficiency?
