Acrylic Resin for Solar Backsheet Coating
HN-2604 Series
Product Introduction:The HN-2604 Series is a solvent-based acrylic resin that, when combined with an isocyanate curing agent, can be used in high-performance solar photovoltaic backsheet coatings. It has excellent compatibility with various types of trifluorinated and tetrafluorinated FEVE resins, allowing for blending in any ratio to reduce fluorine content and save costs. It also offers excellent adhesion to PET and EVA substrates, and performs well in humidity and heat aging, passing the PCT 48h aging test with proper formulation. The resin exhibits excellent mechanical properties and can be directly used in the grinding of coatings.
