Plastic Laser Marking additives Must involve Injection molding or extrusion process and can work only with Fiber and Yag lasers.
It is NOT something you can apply on pre-existing plastic parts and mark with laser. It has to be processed with molding. Lazact Black or Lazact white is available in master batch form (small plastic granules) which can be mixed with your resin at 2-5% LDR by weight of the molding shot. The molding machine screw then mixes it with your resin in the barrel at 200 to 400 F and is then injected in your steel mold at a high pressure.
