【Huicong Silk Screen Printing NetworkReport] Recently, Shanghai Youn Chemical Co., Ltd. launched a new productink single-component cross-linking agent UN-7038. UN-7038 is a water-dispersed blocked polyisocyanate cross-linking agent that can be used as a one-component cross-linking agent such as acrylic or polyurethane solvent-based inks and water-based inks.

(Jiangxi New Materials Co., Ltd.)

As an ink cross-linking agent, it is added to screen printing inks, gravure inks, retort-resistant composite inks, roller coating inks, industrial coatings, and polyurethane System, PU system, nylon system, particularly good miscibility, improve the ink’s light resistance, heat resistance, cooking resistance, weather resistance, wear resistance, scratch resistance, solvent resistance, acid resistance, alkali resistance and other properties , obviously assists the stability of ink quality, especially can enhance adhesion, speed up the drying speed of inks, coatings, and adhesives, and increase the glass transition temperature (TG point).

Typical properties

Appearance: light yellow viscous liquid

Solid content: about 85%

PH value: 7-8

Proportion: 1.05

Recommended uses

Suitable for all solvent-based inks and water-based inks; immortal inks!

After the ink film is formed, the adhesion of the ink on PET and other substrates is improved.

Resistant to various solvents such as acetone and alcohol scrubbing! More than 20 times, resistant to tape adhesion! Dishwasher resistant!

Recipe suggestions

The general dosage is 1-5%, and you can try it out based on your needs. The heat treatment temperature must be above 100°C, and the optimal temperature is 160°C. The cross-linking effect can usually be obtained in 10-30 minutes. Adding a certain amount of organotin catalyst can shorten the cross-linking time. The higher the temperature, the shorter the processing time.

Storage packaging

Stored at room temperature for 12 months. Packaging is 5KG
