Fastrack HD-21A Binder was developed by DCM to meet the need for increasing durability and decreasing dry time when striping roads with waterborne traffic paint in excess of 15 wet mils. Featuring patented quick-dry technology and a patented cross-linking mechanism in the latex binder, Fastrack HD-21A Binder accelerates the dry speed of waterborne road stripes that are up to two times thicker than standard and durable enough to adhere to a variety of roadway substrates says the company.
DCM says Fastrack HD-21A Binder can also help raise the sustainability profile of traffic markings. The company recently conducted a Life Cycle Assessment (LCA) to compare the environmental and human health impacts of road striping facilitated by high-build paint based on Fastrack HD-21A High-durability Waterborne Binder versus hot melt thermoplastic. The results, validated by an objective third party, demonstrate a smaller impact potential when using Fastrack High-Build Binder Systems. Fastrack Systems were shown to reduce road striping's impact potential in 10 out of 10 categories documented by the LCA including a 250% VOC reduction, a 175% human toxicity reduction and a 250% chemical oxygen demand reduction.
"Moving from solventborne to waterborne paint traffic paint was a step-change for the traffic paint industry back in the 90s and we see another opportunity today to reduce the environmental impact of road markings considerably by replacing thermoplastic systems with high-build paint systems made with Fastrack HD-21A Binder," says Cindy Randazzo, technical service manager, Dow Coating Materials. "These benefits, along with the cost and material efficiency of a longer-lasting stripe, will go a long a way in helping the industry meet its sustainability goals."
