Used as a protective coating material due to its excellent resistance to weathering and UV degradation. Commonly applied in outdoor coatings where long-term stability is required. Serves as a compatibilizer in polymer blends, improving phase adhesion between dissimilar polymers. Employed in photoresists and lithography processes in microelectronics due to its favorable thermal and chemical resistance. Also utilized in specialty adhesives and sealants where enhanced durability is needed.
