Silane coupling agents are chemical compounds that are used to enhance the adhesion and compatibility between two dissimilar materials, typically in the context of polymer composites, adhesives, sealants, and coatings. These agents have a silane functional group (Si-O) at one end and a reactive organic group at the other end. They are primarily used to improve the bonding between inorganic surfaces (e.g., glass, metal, ceramics) and organic polymers, such as thermoplastics or thermosetting resins. Silane coupling agents play a crucial role in various industries, and their demand is driven by their ability to improve the performance and durability of composite materials. The global silane coupling agents market size is estimated to grow from USD 1.2 billion in 2021 to USD 1.6 billion by 2026, at a CAGR of 5.5% during the forecast period.
