Eastman CAP-482-0.5 is a low - odor modified resin in the cellulose acetate propionate series, specially customized for high - performance systems such as printing inks and overprint varnishes. With high propionyl content, it has excellent solubility and miscibility, can accelerate solvent release to shorten drying time, inhibit intercoat bleeding and lifting
Low - Odor & Environmental Adaptability - Almost odorless, suitable for odor - sensitive scenarios such as printing and packaging, meeting food - contact related standards
Efficient Drying Acceleration & Oil Resistance - Accelerate solvent volatilization to shorten touch - dry time, improve coating oil and stain resistance, and ensure long - term quality of printed matter
Broad Compatibility & Stability - Miscible with acrylic, polyurethane and other ink and coating resins, optimize leveling, eliminate shrinkage cavities and prevent sagging
High Hardness & Blocking Resistance - Endow coatings with high hardness and blocking resistance, improve the wear resistance of overprint varnishes, and adapt to high - speed printing processes
High - end Printing Inks - Improve ink leveling and anti - sagging capabilities, enhance adhesion and oil resistance, and ensure clear and bright printed patterns
Overprint Varnishes - Endow varnishes with high hardness and blocking resistance, improve the gloss and wear resistance of printed matter, and adapt to food packaging printing
Paper & Fabric Coating - Improve the surface properties of paper and fabric, enhance oil resistance and printing adaptability, and adapt to high - grade packaging materials
Cigarette Filter Coating - Take advantage of low odor and oil resistance to improve the surface stability and use safety of filters
