Used as a surface modifier in coatings and adhesives to provide water repellency, oil resistance, and low surface energy. Enhances durability and weather resistance in outdoor coatings. Commonly applied in optical materials and electronic encapsulants due to its transparency and thermal stability. Improves release properties in mold coatings and facilitates smooth demolding. Frequently utilized in specialty silicone formulations where fluorinated groups are needed for chemical resistance.
