LaserMark-W™ is a laser-responsive functional additive designed to improve marking contrast on light-colored or difficult-to-mark polymer systems. It is used to enable clearer, higher-contrast codes under common industrial laser wavelengths by promoting controlled, localized surface/optical change during irradiation.
Under laser exposure, LaserMark-W acts as a laser-activation additive (not a conventional color pigment). It helps convert laser energy into a localized response at the marking zone, improving visual contrast and edge definition. Final mark appearance depends on polymer chemistry, filler/pigment package, additive loading, and laser parameters.
LaserMark-W is typically evaluated in light or natural polymer systems where contrast is limited by base formulation. Compatibility must be confirmed by trials on your exact resin grade and color package. Common evaluation families include PP, PE, PA, ABS, PC, and relevant blends/compounds used for industrial parts.
The effective process window is defined by your laser configuration and the compounded formulation. During trials, vary one factor at a time (loading, speed, power, focus) and verify: (1) code readability, (2) edge definition, and (3) repeatability across parts/batches. Establish acceptance criteria based on the end-use environment.
Conventional pigments primarily provide color and broad absorption, but may not yield sufficient contrast or clean edges on certain light substrates. LaserMark-W is positioned as a functional laser-response additive aimed at improving the marking response under irradiation rather than serving as a colorant. Selection should be based on readability targets and process robustness.
When conductive fillers are used (e.g., for ESD parts), laser marking response can change due to altered optical/thermal behavior. Validate LaserMark-W on the full conductive formulation, focusing on code readability and surface integrity. Related material: SWCNT Slurry.
