What SEM Products, Inc does
SEM Products, Inc. is a Rock Hill, South Carolina-based manufacturer of specialty automotive refinish chemicals, founded in 1949 (some sources state 1948) and operating as a privately held corporation with 101-250 employees. The company formulates and produces repair, refinishing, and protective coating products — including adhesives, seam sealers, plastic-repair systems, flexible coatings, primers, clearcoats, truckbed liners, and rust/corrosion treatments — distributed primarily under proprietary sub-brands such as Dual-Mix, Color Coat 3, 4Plastic, Gladiator XC, Rock-It XC, Bumper Coater, and Trim Black Ultra. Its underlying technology base includes patented and patent-pending innovations (Mix'n'Shake automated stirring device and cup, ORBiT ripple-bead installation tip, T3 True Tint non-yellowing technology) plus specialty systems such as the VCS cup system and Power Station aerosol filler; the Mix'n'Shake device is engineered to integrate with the PPG LINQ digital ecosystem.
The company generates revenue through one-time product and equipment sales, sold exclusively via a tiered distributor and jobber network across the United States, Canada, and — as of May 2026 — Mexico, with an additional private-label program for qualifying partners. Pricing is quote-based and not publicly disclosed. Customers span collision repair centers (the primary segment), commercial fleet operators, marine repair facilities, aerospace repair facilities (FAR-compliant lines), and restoration/Upholstery specialists; OEM endorsements include Fiat Chrysler Automobiles (14 recommended products) and General Motors (52 recommendations covering 218 SKUs), which are central to shop-level trust and switching inertia. The go-to-market motion combines distributor-channel sales with content marketing, I-CAR alliance training, and technical support infrastructure (Tech Support and Customer Care), reinforcing the role of distribution and technical credibility as the primary economic moat.
SEM has accelerated product cadence and geographic reach over 2025-2026, launching four new product platforms (Mix'n'Shake, 4Plastic, Purple AVS Abrasives, Color Coat 3) and entering Mexico, while continuing its 2019 exclusive U.S./Canadian distribution partnership with Mothers Professional products. Founded by Don and Marilyn Scranton, the company is currently led by President Steve Fussy and remains headquartered at 1685 Overview Dr., Rock Hill, SC.
