Modified Polyester Acrylate 5335B is the "Performance Hexagon Warrior" of UV Printing Coatings. In the field of UV printing and coating, modified polyester acrylate 5335B—with its comprehensive properties of rapid curing, excellent flexibility, high gloss retention, superior adhesion, and outstanding pigment dispersion and flow characteristics—has emerged as the innovative engine behind UV color inks, varnishes, and offset inks. It enables the industry to break through dual bottlenecks in both efficiency and quality.
Under UV activation, complete crosslinking is achieved within 3 seconds (energy density ≥100 mJ/cm²), making it compatible with high-speed offset printing lines running at 120 meters per minute. This represents a 50% efficiency improvement over conventional resins.
The cured film exhibits a fracture elongation greater than 150% (ASTM D638) and achieves a 5B adhesion rating (ASTM D3359) on substrates like BOPP and aluminum—effectively resolving ink delamination challenges.
Its nano-level leveling properties impart a 60° gloss value of at least 95 GU (ISO 2813). Exceptional pigment dispersion (D50 ≤0.5 μm) enhances color saturation by 30% for high-gloss book covers and luxury packaging.
A low viscosity (≤300 cps at 25°C) combined with high shear-thinning characteristics guarantees uniform ink spreading during high-speed offset printing, achieving a dot reproduction rate of over 98%.
