ZyCoat ZyBar Thermal Coating

ZyCoat ZyBar thermal coating is a high temperature thermal dissipation coating for headers, manifolds, turbos, and exhaust systems. By greatly reducing radiant engine heat, ZyBar improves scavenging performance to boost torque and increase horsepower. Utilizing advanced, micro-surface technology, even a very thin .001 to .0012 mil coating of ZyBar outperforms conventional tapes, wraps, ceramic, or powder coatings. ZyBar's improved engine performance was confirmed by measuring header surface temperature reduction versus stock, uncoated headers. Utilizing revolutionary, lightweight micro-surface technology, ZyBar significantly reduces surface temperatures which, in turn, lowers under-the-hood temperatures, and lessens the need for heavy wraps, tapes and shields. Additional features of ZyCoat ZyBar thermal coating include: * Lower applied cost … less than 1/3 the cost of ceramic coating * Increased scavenging performance for increased engine performance * Color stability and corrosion resistance * Conquers temperature extremes up to 2000+ degrees F * Reduces radiant heat by over 90 percent * Accelerates thermal flow to increase horsepower * Resists rust and corrosion--won't chip or crack * Spray, dip, or wipe application * Choice of colors
