When you require performance, reliability, and quality the PK compounds are where to turn to. The PK-Zero offers many of the same excellent benefits of the PK line, but at a budget price. It is easy to apply, requires no burn-in time, has a long lifespan with low dry-out, and is not electrically conductive. The nanoparticles help to fill in microscopic imperfections in the surfaces between the heat sink and contact surface, providing leading brand thermal dissipation!
