Name: Addivant ROYALTUF 498 Coupling Agent
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Addivant ROYALTUF 498 Coupling Agent

High-efficiency silane-based coupling agent designed for enhanced interfacial adhesion between inorganic fillers and organic polymer matrices.
Improved hydrolytic stability compared to conventional amino-silanes, enabling longer shelf life and consistent processing performance.
Enables superior mechanical property retention—especially tensile strength, flexural modulus, and impact resistance—in filled thermoplastics and thermosets.
Low volatility and reduced amine odor, supporting safer handling and improved workplace air quality during compounding operations.
Compatible with a broad range of resins including polyolefins, engineering plastics (e.g., PA6, PBT), epoxies, and unsaturated polyesters.

Typical Applications Of Addivant ROYALTUF 498 Coupling Agent

Reinforced polypropylene (PP) compounds for automotive interior and under-hood components.
Calcium carbonate and talc-filled polyethylene (PE) for high-stiffness packaging and construction profiles.
Glass fiber-reinforced nylon (PA6/PA66) used in electrical connectors and structural housings.
Mineral-filled epoxy composites for printed circuit board (PCB) laminates and encapsulation materials.
Hybrid filler systems (e.g., silica + clay) in rubber and thermoplastic elastomer (TPE) formulations.
