Cemedine Y-358AB: Innovative High-Performance Speaker Magnetic Circuit Adhesive

Cemedine is a top Japanese adhesive brand with a history dating back to 1923. The name "Cemedine" is derived from the combination of "Cement" and "Dyne" (a unit of mechanical force), symbolizing its strong bonding capability. Since its inception, Cemedine has focused on developing and producing high-performance adhesives, including silicone, epoxy, acrylic, and other bonding solutions widely used in electronics, machinery, automotive industries, and more. The company possesses proprietary modified silicone technology and has obtained international certifications (e.g., UL certification). Its products are known for ​high strength, fast curing, and resistance to extreme environments​. Cemedine is not only a synonym for the Japanese adhesive industry but also an exemplary story of a local brand going global.

Cemedine Y-358AB is an epoxy AB adhesive specifically designed for ​speaker magnetic circuit assembly, also known as speaker magnetic circuit adhesive. It consists of Agent A (blue) and Agent B (orange-red), which undergo a chemical reaction when mixed to form a high-strength, durable bond. Its core features include:

• ​Rapid Curing: Initial hardening within 5–6 minutes after mixing, suitable for high-efficiency production lines.
• ​Environmental Resistance: Withstands high temperatures (150°C), low temperatures, vibration, impact, and aging, ensuring stability in extreme conditions.
• ​Eco-Friendly and Safe: Complies with EU ROHS directives and is free of prohibited hazardous substances.
• ​Versatility: Besides speaker magnetic circuits, it can be used for bonding electrical components, metal crafts, stone, plastic, and wood.

The physical and chemical properties of Y-358AB are precision-optimized for industrial needs:

The primary application of Y-358AB is ​speaker manufacturing, especially for bonding neodymium magnets, where it prevents sound distortion. It is also widely used in:

1. ​Electronic Mechanical Components: Such as circuit board encapsulation and sensor fixation, providing insulation and shock protection.
2. ​Metal and Stone Crafts: Bonding decorations and sculptures, with weather resistance ensuring durability for outdoor use.
3. ​Industrial Maintenance: For equipment sealing and pipeline loosening prevention (e.g., screw anti-vibration), replacing traditional welding.

To ensure optimal results, follow these steps when using Y-358AB:

1. ​Mixing Ratio: Mix Agent A and Agent B at a 1:1 weight ratio until the color is uniform.
2. ​Working Environment: Operate in a well-ventilated area away from open flames (due to flammable content).
3. ​Storage Requirements: Store sealed in a cool place, avoiding environments with humidity above 60%.

• Wear gloves and goggles during application to avoid direct skin contact.
• The curing process produces no volatiles, but those sensitive to odors should wear masks.
