With roots tracing back to aerospace applications—including coatings originally applied to the X‑30 Space Plane fuselage—Tech Line Coatings has spent over three decades refining high-performance coatings for automotive, industrial, and commercial use. Based in Tennessee, the company’s global reach is supported by a network of over 1,000 applicators worldwide.
What sets Tech Line apart is their mastery of thin-film ceramic technology—coatings that not only endure extreme heat (up to 2,000 °F/1,093 °C) but also offer thermal management, corrosion resistance, lubrication, and aesthetics. Their portfolio spans from CermaKrome metallic finishes to powder coatings and thermal dispersants.
🖤 Spotlight on Black Satin™ (Part #BHK)
Arguably Tech Line’s flagship product, Black Satin™ is a ceramic-reinforced, satin-black coating engineered for the harshest exhaust environments:
-
Extreme Temperature Resistance
Capable of withstanding substrate temperatures over 2,000 °F, while maintaining stability up to ~1,600 °F in prolonged service. -
Superior Thermal Barrier
Its ceramic nature significantly reduces radiant heat, lowering under‑hood temps, improving exhaust gas velocity, and enhancing horsepower and torque. -
Tuning Aid
Black Satin undergoes colour shifts with temperature—offering a visual indicator of heat levels, potentially beneficial for engine tuning. -
Flexible Application & Cure
Designed for air drying and exhaust-heat curing, it also supports full oven cure (~700–750 °F for 1 hour) to achieve maximum chemical, moisture, and corrosion resistance -
Durable & Adhesive
Exhibits excellent adhesion (ASTM tape test 5B), pencil hardness of 8+, and strong flexibility—surviving thermal shocks and cycling
🔧 Application Guide
-
Surface Prep: Grit-blast with 120 grit aluminium oxide (no glass bead). Clean thoroughly with acetone or lacquer thinner.
-
Coating: Apply a single thin coat (.001–.0015″) with spray equipment. Avoid multiple passes to preserve adhesion
-
Cure Cycle: Air-dry quickly, then cure via exhaust heat or in an oven per guidelines (500 °F partial, 700+ °F full cure)
-
Caution: High initial exhaust temps can compromise the resin—engine tuning must be dialled first
-
Compatibility: Can be applied over base-coats like PrevCor, MCS, or HHBK to enhance thermal and corrosion protection
🌟 Why Choose Black Satin?
-
Performance Impact: Reducing radiant heat delivers meaningful gains in under-hood temperature and engine efficiency.
-
Longevity & Protection: Excellent resistance to corrosive agents like salt, water, fuel, and solvents—especially after full cure
-
Visual & Functional: Classic satin-black finish looks great and delivers thermal benefits.
-
Pro Proven: Trusted by performance tuners, OEMs, and industrial customers who require advanced thin-film technology.
