Base Estuco PPL-624: High-Leveling White Primer for Flexography
Base Estuco PPL-624 is a premium water-based white coating designed specifically for paper substrates. Its primary function is to create a smooth, leveled surface that drastically optimizes printability in flexographic processes. It acts as a high-performance preparatory layer to enhance ink anchorage, reduce irregular absorption, and guarantee a uniform finish, even on cellulose substrates with variable textures. Formulated with advanced water-based technology, it offers excellent compatibility with both coated and uncoated papers, adapting seamlessly to different basis weights and the rigorous operational demands of the modern packaging industry.
- Homogeneous and leveled surface: Reduces inherent paper irregularities, preventing the undesired mottle effect and significantly enhancing the visual quality of the final print.
- Superior ink anchorage and stability: Promotes excellent color adhesion, preventing migrations and printing defects, which is critical in high-quality graphic applications.
- High industrial processability: Fully compatible with high-speed flexography presses, offering outstanding mechanical behavior during post-processing operations such as die-cutting, creasing, and folding.
- Sustainability and low impact: Water-based formulation with low Volatile Organic Compounds (VOC) emissions, contributing to the development of cleaner and highly recyclable packaging solutions.
