What is Chemlok207LH?
Chemlok207LH is a low Hazardous Air Pollutant (HAP) primer designed to be used beneath Chemlok 6411LH covercoat adhesive. It is formulated to bond a broad range of rubber compounds—both vulcanized and unvulcanized—to metal and rigid substrates. This primer consists of polymers, organic compounds, and mineral fillers dispersed in a low-HAP solvent system, offering high durability with reduced environmental impact.
