Conductive adhesives have gained increasing importance alongside the evolution of electronic devices. This section introduces their basic principles, formulation technology, historical development, and the innovative advantages offered by ONE-HAND MIXING®.

✅What Are Conductive Adhesives?

A conductive adhesive is a material that conducts electricity after curing, achieved by dispersing conductive fillers - such as silver or copper particles - within a resin matrix.

• Resin matrix: Provides mechanical strength and durability. Typical systems include epoxy or acrylic resins.

• Conductive fillers: Such as silver or silver-coated copper particles, which provide electrical conductivity.

By combining these two components, conductive adhesives simultaneously offer both adhesion and electrical conductivity in a single material.

✅Advances in Formulation Technology

The performance of conductive adhesives is largely determined by optimizing filler composition and resin design, including particle size, shape, ratio, and surface treatment technologies.

• Filler design: Spherical silver particles provide good flow characteristics, while flake-shaped particles ensure reliable conductivity. Recent advances in nanoparticle and surface modification technologies have enabled lower resistance and more stable bonding.

• Resin design: Formulated to balance curing speed, heat resistance, and flexibility depending on the application. Automotive applications emphasize durability, while electronic components require flexibility for fine-pitch patterns.

Through these formulation improvements, conductive adhesives now achieve low electrical resistance comparable to solder while maintaining high bonding reliability.

✅Historical Development

The practical use of conductive adhesives dates back to the 1970s, when they were primarily used for semiconductor packaging and defense applications.

• 1980s–1990s: With the expansion of mobile phones and LCD displays, their use spread to flexible circuits and transparent electrodes.

• 2000s onward: Driven by lead-free initiatives and environmental regulations, conductive adhesives gained attention as an alternative to solder.

• Recent years: The electrification and digitalization of automobiles, along with the rise of wearable electronics, have accelerated their adoption.

As a result, conductive adhesives have evolved from a specialty material into a mainstream, mass-production-compatible technology.

✅Growing Demand and the Innovation of ONE-HAND MIXING®

Within this long history of conductive adhesive development, ONE-HAND MIXING® was designed with the concept of “making high performance easier to use.”

1. Room-temperature curing without heat damage: Safe for precision components and flexible substrates.

2. Low resistance and strong adhesion: Achieved through optimized silver filler formulation

3. Excellent coating durability: Once cured, it resists wiping and abrasion, maintaining long-term stability.

4. Revolutionary ease of use: With its special dual-cartridge system, the two components automatically mix and dispense with a single push - eliminating manual mixing and ratio management.
