Promoter adhesion additives are specialized compounds that enhance the bonding strength between different substrates, especially in challenging applications where adhesion is difficult to achieve. By modifying the surface properties of materials, these additives improve the wettability and chemical compatibility of adhesives, coatings, and sealants, leading to stronger and more durable bonds.
