/ USE OF A MIXTURE COMPRISING SPHERICAL METAL PARTICLES AND METAL FLAKES AS LASER-MARKING OR LASER-WELDABILITY AGENTS AND LASER MARKABLE AND/OR LASER WELDABLE PLASTIC

摘要

In the form of volume average cumulative small particle size distribution, spherical metal particles and spherical metal particles in the mixture as measured by laser particle size D _mixture having a particle size distribution of less than 100 탆 _{, 90} value and D _mixture less than 60 탆 _{, 50} value And to the use of the plastic of the mixture comprising spherical metal particles and metal flakes as a laser marking agent or as a laser welding agent. The present invention also relates to a master batch comprising a mixture comprising spherical metal particles and metal flakes. The present invention further relates to a laser-markable and / or laser-weldable plastic comprising a mixture comprising spherical metal particles and a metal flake.
