Product Description:
Used primarily as a key component in the production of safety glass, it enhances the durability and safety of laminated glass by acting as an interlayer. This interlayer helps hold the glass together upon impact, reducing the risk of injury from sharp shards. It is also employed in coatings and adhesives, providing excellent adhesion, flexibility, and resistance to UV light. In the automotive and construction industries, it improves the performance of glass used in windshields and architectural applications. Additionally, it finds use in the manufacturing of photovoltaic modules, where it serves as an encapsulant for solar panels, ensuring longevity and efficiency.
