About Technical Chemical Company (TCC)
Technical Chemical Company (TCC) has been a cornerstone of the automotive aftermarket chemical industry since 1928, when it launched its flagship Johnsen's brand of automotive fluids and aerosols. Based in the Dallas/Fort Worth metroplex, TCC has grown from a regional packager into a nationally and globally recognized manufacturer trusted by professional technicians and everyday drivers alike.
What sets TCC apart is the breadth and depth of its chemical expertise. Refrigerant oils and A/C leak sealants represent some of the brand's strongest areas, reflecting decades of specialization in air conditioning system maintenance. Whether you're recharging a vehicle's A/C system or stopping a slow refrigerant leak before it becomes a costly repair, TCC's formulations are engineered to keep HVAC systems running efficiently.
On the braking side, TCC's brake fluid lineup — including DOT-rated formulas — meets the demanding standards required for safe, reliable stopping power. Brake fluid is often an overlooked service item, but its hygroscopic nature means it degrades over time; TCC offers solutions that help maintain the integrity of hydraulic braking systems.
The Johnsen's brand also covers everyday maintenance essentials. Their windshield and headlight washer fluids keep visibility clear in all weather conditions, while power steering fluid formulations help preserve the responsiveness and longevity of power steering systems — both traditional hydraulic and compatible modern setups.
Beyond its own Johnsen's house brand, TCC provides private-label packaging services for well-known names throughout the automotive aftermarket and HVAC industries, a testament to the manufacturing quality and consistency that other brands trust. TCC also produces stock and custom plastic bottles for the aftermarket chemical industry, making it a vertically integrated partner across the supply chain.
