Production and supply of metal nano ink (conductive ink) | C-INK Co., Ltd.

The main solvent in DryCure Au-J and Ag-J is water. Non-polar solvents cannot be used.

Currently, we do not manufacture solvent-based nano ink.

C-INK currently does not manufacture nano inks made of copper Cu, nickel Ni, platinum Pt, etc.

C-INK nanoink is optimized for inkjet printing. For inkjets, please use DryCure Au-J and Ag-J. We can provide inks for all types of inkjet heads. If adhesion to substrates such as untreated PET, glass, and glass epoxy is required, please use DryCure Ag-JB, a binder additive grade. The DryCure series cannot be used for screen printing as the viscosity is a few millipascals. In regards to ink selection, we will propose the most suitable ink based on your equipment configuration, etc., so please do not hesitate to contact us about your requirements.

Resin films such as PET and glass substrates can be used. When printing on commercially available easy-to-adhere PET film, strong adhesion can be obtained by heating the film to 120°C for about 10 minutes after drying. For resin substrates, first try heating after printing. We have confirmed adhesion to various resin substrates such as polyimide with thermoplastic layers, liquid crystal polymer film, ETFE etc. For substrates where adhesion is not normally possible, binder-added grades (DryCure Ag-JB) can be used.

C-INK's nano ink aggregates and precipitates when salts are mixed. When using, use clean utensils and containers free of salt. In addition, please use up the ink filled in the cartridge or tank in about two weeks after filling. The filled ink is in constant contact with air, slowly oxidizing the nanoparticles. Oxidized nanoparticles can cause nozzle clogging. If you do not use the nano ink continuously, clean the channels and heads with cleaning liquid to remove the ink from the printer.

Please store the ink in a refrigerator. All DryCure series inks are insoluble in solvents once dried. When the ink is stored in a container that has expanded with gas, the solvent repeatedly evaporates and condenses in this space, causing dry metal solids to gradually precipitate out in the process. To prevent this, please remove as much air as possible from the container before storing to minimize contact with oxygen, preventing the ink both from drying and deterioration due to oxidation. (Deterioration due to oxidation can occur with DryCure Ag.) The DryCure series will also experience agglomeration upon contact with salts. Please use clean containers that do not contain salts for both storage and use.

The minimum sales amount is as follows. ・Gold nano ink (DryCure Au-J, JB) Gold solid content 3g (concentration 10wt%; ink volume approx. 27mL) ・Silver nano ink (DryCure Ag-J, JB) Silver solid content 10g (10wt%; about 90mL, 20wt%; about 40mL)

Once dried, DryCure is insoluble in water and other solvents. This property can be used to apply multiple coats of ink.

Store in a place with a room temperature of 40°C or less, out of direct sunlight, and tightly sealed.

Same quality.
