Direct Answer: (Basic) Copper Hydroxyl Phosphate(a.k.a Copper Hydroxide Phosphate) enables neutral gray laser markings by absorbing NIR radiation, converting it to heat and triggering char formation for precise polymer marking.
LaserMark-G™ is a zirconium nitride (ZrN) based marking additive designed to help glass surfaces develop visible contrast under laser irradiation. It is used by formulators and process engineers to build stable, production-ready marking systems for glass parts where direct laser marking is required.
Glass is optically transparent across much of the visible range and has low absorption at many process wavelengths. As a result, the laser energy may pass through or distribute without producing a controlled surface change. In addition, smooth glass surfaces provide limited anchoring points, so any mark that relies on deposited material must also pass adhesion and abrasion requirements.
Note: Mark appearance and durability depend on the complete system (glass type, laser, binder, dispersion, thickness). LaserMark-G™ is supplied as an additive material, not a finished marking ink.
LaserMark-E is a laser marking additive optimized for electronic plastics and precision components. It delivers clear, durable laser markings with controlled contrast while preserving electrical, mechanical, and surface integrity required in electronic and ESD-sensitive applications.
LaserMark-P is a laser marking additive designed for robust processing windows and consistent contrast generation on plastics. Unlike conventional pigments, it responds to laser energy through functional activation mechanisms, enabling reliable marking performance across varying molding and laser conditions.
Black titanium dioxide enables laser marking by absorbing 1064 nm laser energy and converting it into localized thermal energy, which induces controlled surface carbonization or contrast formation in thermoplastics without bulk material degradation.
LaserMark-SF is a laser-responsive functional additive that enables light, foamed contrast marking on dark or high-absorption engineering plastics. It generates clear, durable markings through controlled surface foaming rather than pigment burning, ensuring high readability without compromising polymer performance.
Antimony Tin Oxide (ATO) enables laser marking by free-carrier near-IR absorption that converts the laser beam into localized heat. The hot zone drives controlled surface chemistry and microstructure change (micro-foaming, carbonization, or mild ablation), producing durable high-contrast marks on engineering plastics.
LaserMark-W™ is an ATO-based laser-activation additive for high-contrast marking on light or low-absorption engineering plastics. It converts near-IR laser energy into localized heat so the scanned surface undergoes controlled micro-foaming, carbonization, or mild ablation to form permanent contrast.
