Cemedine 1500: A Reliable Solution for Speaker Magnetic Circuit Bonding and Sealing

In the speaker manufacturing industry, the bonding and sealing of the magnetic circuit system are critical factors determining sound quality and product lifespan. Cemedine 1500, as a standard two-component epoxy resin adhesive, has become the preferred material for many audio manufacturers due to its excellent bonding strength and insulation properties.

• High Bonding Strength: According to product data, its tensile shear strength reaches 15.7 MPa, enabling it to firmly bond metal components such as magnets and pole plates, effectively preventing magnetic circuit loosening or detachment under severe vibration.
• Excellent Insulation: With a volume resistivity of up to 7.1*10¹⁵ Ω·cm, it effectively isolates the magnetic circuit system from the voice coil, preventing short circuits and ensuring electrical safety.
• Weather Resistance and Stability: It features low curing shrinkage and good resistance to heat, weather, and chemicals, ensuring the stability of the bonding layer during long-term use or in harsh environments, without degradation in sound quality due to aging.

• Magnetic Circuit Bonding: Used for bonding the magnet and pole plate (T-Yoke) of the speaker to form a robust magnetic circuit structure.
• Center Glue: Used for bonding the voice coil to the spider, ensuring the voice coil remains centered in the magnetic gap to prevent rubbing.
• Electronic Component Sealing: Used for potting and sealing circuit boards or electronic components, providing moisture and dust protection.

Cemedine 1500 not only solves the structural bonding challenges in speaker production but also provides a "zero-defect" manufacturing guarantee for audio products through its stable physical and chemical properties, making it a key material for enhancing product reliability and sound quality performance.
