PO-1 is widely used as a high-performance polymer additive in advanced coating formulations. It enhances thermal stability and UV resistance, making it ideal for protective coatings in aerospace and automotive industries. Its strong adhesion properties improve coating durability on metal and composite surfaces exposed to extreme environments. PO-1 is also employed in specialty inks and electronic encapsulants due to its excellent dielectric characteristics and resistance to moisture absorption. In additive manufacturing, it serves as a crosslinking agent in photopolymer resins, improving print resolution and mechanical strength of 3D-printed parts.
