Enhances interfacial adhesion between polar substrates (e.g., metals, glass, plastics) and non-polar polymer matrices.
Improves mechanical bond strength and long-term durability in demanding environmental conditions.
Compatible with polyolefins, thermoplastic elastomers, and reactive hot-melt formulations.
Enables low-addition-level performance—typically effective at 0.5–3.0 wt% loading.
Thermally stable up to 280 °C, supporting high-temperature processing such as extrusion and injection molding.
Automotive interior trim bonding (e.g., PP/TPO substrates to PVC or PU foams).
Industrial laminates for flexible packaging requiring metal-to-polymer adhesion.
Co-extruded multilayer films where interlayer adhesion between PE and EVOH is critical.
Adhesive primers for wire & cable jacketing over aluminum or copper conductors.
Engineering composites incorporating mineral-filled polypropylene and functional coatings.
