Halogen free ink in the printing process should pay attention to what?
1. diluent choice: Standard diluent TPA-100, slow dry diluent TPA-200.2., the use of ink by the deployment method: TPA ink: 100 copies of curing agent: 15 diluent: 20-30 copies, according to the above proportion of mixing, thoroughly mix thoroughly, static for 20 minutes after printing (mixed ink life 8-10 hours)3. drying method: A, strengthening treatment of PC, acrylic, vacuum plating parts: 70 degrees -80 DEG C, bake for 60-90 minutes, B, metal, glass: 130 degrees -150 DEG C, bake for 30 minutes4. because of the complexity of printing materials, users should try a small number before batch use and fully confirm the requirements before they can be used in batches5.TPA ink and different series and brand of ink can not be mixed with each other, so as to avoid adverse reactions6.TPA ink should be stored in a cool and dry place. Sealed with the back cover. Avoid contact with open flame and high temperature7.TPA ink shelf life is 24 months

TPA halogen-free ink is a multifunctional advanced printing ink. On ABS, the surface enhanced wear process PC, acrylic, metal, glass, ceramic, melamine products, baking paint, vacuum plating, surface treatment, engineering plastics, PP, PE and other materials, has excellent adhesion and chemical resistance.
