We see brightly colored and intricately patterned PVC (polyvinyl chloride) products everywhere, from advertising signs and packaging labels to electronic product casings, automotive interiors, and even building material surfaces.
In modern industrial manufacturing, labeling, decoration, and functional printing on metal surfaces are ubiquitous—from text labels on home appliance panels to warning symbols on device casings, from serial numbers on electronic products to anti-counterfe
Since the surface energy of PE material is low, the ink needs to have good leveling properties to ensure adhesion.
Specialized PVC inks maintain film integrity and toughness under extreme deformation conditions due to their unique formulations, which are deeply integrated with materials science principles.
Thixotropy refers to the property that the viscosity of ink decreases under the action of shear force and recovers after standing.
During the cross-linking reaction of the curing agent in the resin system, its reaction behavior and the resulting film quality are significantly affected by ambient temperature and humidity.
