Base Fondo Elite SP-18: High-Whiteness Primer and Perfect Sealing for MDF
The Base Fondo Elite SP-18 is a high-whiteness technical primer specifically engineered for application on fiberboard (MDF/HDF and derivatives). Its advanced water-based formulation acts as a powerful sealer that fills the pores and significantly reduces fiber lifting, creating an ultra-smooth, leveled surface with outstanding opacity. Developed for the technical wood printing industry, this primer optimizes the performance of flexographic inks, ensuring superior color reproduction and maximizing color intensity within a sustainable production framework.
Operational Advantages on Press
- High whiteness and maximum opacity: Drastically improves coverage and color fidelity, allowing for a significant reduction in flexographic ink consumption during the print run.
- Superior leveling and pore sealing: Generates a perfectly homogeneous surface that prevents typical printing defects such as mottle and banding.
- Excellent flexographic ink anchoring: Stabilizes the surface energy of the substrate, ensuring clean, uniform printing with high adhesion for both water-based and UV ink systems.
- Versatile industrial processability: Suitable for application by roller, curtain, or spray. It offers fast drying and optimal sandability in processes requiring refinishing.
- Sustainable profile (Eco-friendly): Its water-based formulation ensures low VOC (Volatile Organic Compounds) emissions, aligning with current environmental regulations.

Logistics, Handling, and Applications
- Recommended Uses: Ideal for manufacturing printed decorative elements (panels, cabinet fronts, furniture), premium technical wood packaging (boxes, cases), and signage or displays demanding perfect legibility.
- Substrate Preparation: It is necessary to validate the density and quality of the MDF. A preliminary fine sanding process is highly recommended to enhance the leveling of the primer.
- Application Adjustments: Viscosity and coating weight on the press must be adjusted to achieve full coverage without oversaturating the substrate.
- Post-processing and Machining: The printed material is suitable for subsequent cutting, milling, and assembly operations. Abrasion resistance and final topcoat adhesion must be tested and validated.
