Do you know why tackifying PP resin enhances adhesive bonding strength? Tackifying resin exhibits excellent compatibility with EVA, SBS, and SIS resins. When it bonds with polymer molecules, the resulting macromolecular system forms an interlocking network structure. This network can be reinforced through chemical or physical cross-linking, thereby generating stronger adhesion. Another function of tackifying resins is to enhance the rheological properties of adhesives, improving their flowability and adhesion performance. This enables more uniform coating application on substrates. Follow me to learn more about chemical engineering knowledge.
