At the 2016 World of Concrete Trade Show in Las Vegas, New Riverside Ochre reported a large attendance and significant traffic at their booth. In addition to the strong interest shown by U.S. manufacturers, companies from Nigeria, Canada, Spain, Dubai, Qatar, China and many from South America also requested samples of their natural iron oxide pigments.
New Riverside used the trade show as an opportunity to showcase 5 new granular pigments with emphasis on the block and paver industry. While two of the colors, NIROX™412 and Redwood are produced from cost effective 100% natural iron oxide pigments, Rosetta Buff, Riverside Tan and Moss Green are granular pigments made by blending both natural and synthetic iron oxides.
While many block and paver companies utilize color dispensers that are set-up for running super sacks of a yellow, two shades of red, and a black pigment, most reported that the second red is rarely or never used. Director of Sales for New Riverside, Chris Sims stated that, “Plant managers have chosen to replace the second red with a cost effective “buff”. This allows them to run either their most commonly used color from just one super sack or a formula that blends the cost effective buff with their yellow, red, and black pigments. The single super sack buff color approach has been a real hit with plant managers because it provides cost savings, improves color consistency and reduces waste from inconsistent batching.”
Are granular pigments widely used? Sims stated that, “over 75% of all pigments used for the block and paver industry in the U.S. are now granular.” As a result, New Riverside is installing a spray dryer to granulate pigments which will begin production in the 4th quarter of 2016.
