Aplicaciones de hoja de aluminio prepintado PVDF

Polyvinylidene fluoride (PVDF) coatings are factory-applied resin-based coating systems, typically embedded with colored pigment particles, that support a variety of matte finish colors. They are most commonly used in architectural coating applications because of their excellent resistance to weathering by sunlight, moisture or temperature. The main material of PVDF is polyvinylidene fluoride resin; the maximum negative characteristic of Fl atoms can form very strong high-strength Fl-C bonds. And the product has a special symmetrical molecular structure, which has strong weather resistance, UV resistance, long durability and anti-corrosion performance, and can maintain a very bright color even if it is used indoors for 20 years. surroundings.
Aluminium wall cladding, curtain walls and roof panels are some of the most common applications of PVDF coatings. PVDF Prepainted Aluminum Sheets are the highest priority of choice for high-class aluminum composite panels, and its composite products are widely used in airports, exhibition centers, administration centers, star hotels, and other symbol buildings.

PVDF coatings for aluminium are applied in a paint booth by means of a liquid spray gun. The following steps outline the complete process to complete a high-quality PVDF coating:
Surface Preparation - A good surface preparation is required for any high quality coating. Good PVDF coating adhesion requires cleaning, degreasing and deoxidation (rust removal) of the aluminium surface. A good PVDF coating requires a chrome-based conversion coat prior to primer.
Primer - Primer effectively stabilizes and protects metal surfaces while improving the adhesion of topcoats.
PVDF Topcoat - Colored pigment particles are added with the topcoat. The top coat is used to provide the coating with resistance to damage from sunlight and water, as well as to increase abrasion resistance. The coating must be cured after this step. The topcoat is the thickest layer in a PVDF coating system.
PVDF Clearcoat - In a 3-layer PVDF coating process, the final coat is a clearcoat, which provides additional environmental protection and allows the color of the topcoat to pass through without damage. The coating must also be cured.

Los recubrimientos de PVDF tienen buena resistencia a la corrosión debido a su buena inercia química. La película de pintura es resistente a productos químicos como ácidos, álcalis, sales y diversos disolventes químicos y actúa como barrera protectora para nuestras bobinas de aluminio recubiertas de PVDF. La película de pintura protectora tiene una alta dureza superficial, alto límite elástico, resistencia al impacto y a la abrasión, y excelentes propiedades físicas y mecánicas.
