Laser aluminum paste

Laser aluminum paste is an optical color-changing pigment. The laser paint/laser ink prepared with it can show different colors with the change of the observation angle, that is, the phenomenon of different angles. It has an obvious dynamic color-changing effect and appears under direct light. Bright and vivid "rainbow phenomenon". Its main components are specially treated flake metal aluminum powder/oxide and dispersant, and the appearance is paste-like.

 

What industry does it apply to?

The screen printing laser ink prepared by the laser aluminum paste can be printed on the surface of various transparent substrates (glass, PET, PC, PMMA, PVC, etc.), used for the surface decoration of home appliance glass, mobile phone panels, home decoration glass sliding doors, etc., and can also be used as Anti-counterfeiting ink.

The spraying laser paint prepared by the laser aluminum paste can be sprayed on any substrate (metal, plastic, wood, paper) surface, used for home appliance housing, mobile phone housing, toys, handicrafts, cosmetics packaging, wine bottles, cigarette packs, car wheels, sports Surface decoration of equipment and leather.

 

how to use?

The laser aluminum paste is a non-floating pigment. The rainbow effect is related to the particle size of the pigment. When 10μm is used, the appearance is uniform and fine, and the 50μm appearance is a thicker bright rainbow flash. The effects of 20μm and 35μm are somewhere in between.

Add an appropriate amount of organic solvent to the laser aluminum paste and stir slowly. Excessive stirring will damage the surface coating of the aluminum paste and reduce the gloss. Therefore, ball milling can not be used for dispersion. It should be used as soon as possible after being fully immersed, dispersed, and unsealed. If it cannot be used up at one time, it should be completely sealed immediately to prevent the solvent in the laser aluminum paste from volatilizing.

The rainbow effect is related to the resin and solvent used in the preparation of paint or ink. Mirror silver resin should be used for preparation. Use a small dose to test before use to determine the best laser effect.
