U.S. Chemical has added two new low-VOC primers to its lineup – 2520 DTM Primer and 2720 2K Urethane Primer. The 2520 Primer is a fast-drying, high-build, direct-to-metal primer with excellent adhesion to bare metal. The 2720 2K Urethane Primer is a two-component acrylic urethane that’s easy to sand and can be applied to a variety of substrates. It provides quality fill, build and color holdout and is ideal for repairs requiring the use of low-VOC primers.
