New product recommendation: UN-7038 single component crosslinking agent UN-7038
Time: 2020-05-22
[Huicong Silkscreen Special Printing Network Report] Recently, Shanghai Youn Chemical Co., Ltd. launched the new ink single-component crosslinking agent UN-7038. UN-7038 is a water-dispersible closed polyisocyanate cross-linking agent, which can be used for single-component cross-linking agents such as acrylic or polyurethane solvent-based inks and water-based inks.
As an ink crosslinking agent, it is added to screen printing inks, gravure inks, retort-resistant composite inks, roll-coating inks, industrial coatings, polyurethane systems, PU systems, nylon systems, and miscibility is particularly good, improving the light resistance and resistance of the ink. Thermal properties, cooking resistance, weather resistance, abrasion resistance, scratch resistance, solvent resistance, acid resistance, alkali resistance and other properties, obvious stability of auxiliary ink quality, especially to enhance adhesion, accelerate ink, paint, The drying rate of the adhesive and increase 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
Applicable to all solvent-based inks, water-based inks; undead inks!
After the ink is formed into a film, the adhesion of the ink to substrates such as PET is improved.
Resistant to various solvents such as acetone, alcohol scrubbing! More than 20 times, adhesive tape resistance! Dishwasher resistance!
Recommended formula
The general dosage is 1-5%, try it according to demand. The heat treatment temperature must be above 100 ℃, the optimal temperature is 160 ℃, usually 10-30 minutes to get the cross-linking effect. Adding a certain amount of organotin catalyst can shorten the crosslinking time. The higher the temperature, the shorter the processing time.
Storage and packaging
Store at room temperature for 12 months. Packaging is 5KG
