We are specialists in Liquid Color Management. With 50 years experience of running liquid color, we don't just understand the process, we invented it.

Riverdale Global brings something truly new to the Plastics Industry - the opportunity to enjoy the economy of liquid color in a clean, sealed delivery system that adds value without adding costs. Our technologies enhance the quality and repeatability of liquid color, increase its cost advantages over concentrate, free you from every complication of handling liquids, and reduce your environmental impact. We offer the most economical and sustainable way to color plastics. Three key components:
1 Single-Pigment Dispersion (SPD)™ Technology
While the conventional method of manufacturing liquid color is simply to add pigments one at a time to a liquid carrier and then blend them, Riverdale Global disperses only one pigment in liquid, then mills this dispersion to maximize color strength, brightness, and uniformity. As a result, processors using colorants based on SPDs can achieve full color at lower let‑down rates than with conventional liquids. The SPDs are produced at one location only and inventoried at Riverdale Global satellite locations, where they are blended to match customer specifications. Additives can be included in blends along with colorants. Because of this 'single-sourcing' of SPDs, multinational customers are supplied with precisely the same colors at multiple plant locations.
2 Riverdale Gravimetric Stand (RGS)
RGS is the first complete Sealed Delivery System™ for Color and Additives, designed exclusively for Riverdale Global by Maguire Products, to prevent the handling complications and workplace mess traditionally associated with liquid color. In this system, the pump is permanently installed inside a standard‑size drum that stays sealed from any contact with the workplace or environment. During processing, color is precisely metered with automatic shutoffs preventing spillage and GlobalTacker™ monitoring software tracking inventory levels. Through Riverdale Global's "return for refill" sustainability program, the processor is credited for residual color in the container and avoids the problem of discarding it.
3 Satellite Network
Riverdale Global satellite's service customers within a narrow radius, providing fast, customized support, ready access in the event of emergencies, and the opportunity for customers to reduce inventories.
