【HC Silk Screen Printing NetworkReport】 Recently, Shanghai Union Chemical Co., Ltd. launched a new product one-component cross-linking agent UN-7038 for ink. 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. As an ink cross-linking agent, it is added to screen printing inks, gravure inks, retort-resistant composite inks, roller coating inks, industrial coatings, polyurethane systems, PU systems, nylon systems, with particularly good miscibility and improved light resistance of inks. Physical properties, heat resistance, cooking resistance, weather resistance, abrasion resistance, scratch resistance, solvent resistance, acid resistance, alkali resistance and other properties, obviously assist the stability of ink quality, especially can enhance adhesion and speed up ink , the drying speed of coatings and adhesives, and increasing the glass transition temperature (TG point). Typical properties Appearance: light yellow viscous liquid Solid content: about 85% PH value: 7-8 Specific gravity: 1.05 Recommended use Suitable for all solvent-based inks, 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 addition amount is 1-5%, and you can try it according to 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
