Exclusive Polymer Nation Distributor · Indiana
ATC Supply in Merrillville stocks the Polymer Nation line deep — epoxies, polyaspartics, urethane cement, primers, topcoats, flake, and aggregates — for same-day pickup or jobsite delivery across Northwest Indiana, South Chicago, and Southwest Michigan.
Why buy Polymer Nation here
This isn’t a paint counter with two colors on order. It’s a working Polymer Nation inventory built for coating pros who need product now.
I drive to the Polymer Nation plant in Waukegan, Illinois every week for material. That keeps the shelves deep and makes same-day pickup the norm: walk in, load out. When you need a hard-to-match color, a bulk quantity, or something outside the standard catalog, I stage it on my next Waukegan run so it’s ready when your crew rolls in.
Before opening ATC Supply, I spent years inside Polymer Nation as National Alliance Manager and in Technical Sales, then ran my own installation jobs across the Midwest. So when you call with a spec question, you’re talking to someone who has trained crews on this chemistry and put it down on real floors.
