Anti electrochemical migration and insulating adhesive

TEISANRESIN is a low-Tg acrylic ester polymers manufactured using our suspension polymerization technology. It is widely used in electronic material adhesives, and as an epoxy resin modifier, for example, to improve flexibility and stress relaxation. It provides excellent electrical insulation and adhesion reliability.

TEISANRESIN contributes to providing following solutions:

1. Improving adhesive strength

Issues

In general, electronic materials often consist of a combination of different materials, such as metals, ceramics, and plastics, making it challenging to ensure sufficient adhesive strength. In particular, adhesives are prone to deterioration and peeling in high-temperature and high-humidity environments.

Solution by TEISANRESIN

• Excellent adhesive reliability: Provides excellent adhesion to various substrates (Cu, PI, Glass, and Epoxy resin, etc.)

• Flexibility and stress relaxation: Disperses stress when bonding hard materials together, reducing the risk of peeling

• Heat resistance: Maintains adhesive strength even at high temperatures (85℃ or above), ensuring long-term reliability. This enables longer life and improved reliability of electronic components

2. Ensuring electrical insulation reliability (prevention of leakage current and short circuits)

Issues

Adhesion to electronic materials requires not only adhesive strength but also electrical insulation. In particular, leakage current around high-voltage circuits and sensors can cause malfunctions and failures.

Solution by TEISANRESIN

• Excellent electrical insulation reliability: Maintains excellent electrical insulation even in a 50V application test under 85℃ / 85%RH

• Resistance to electromigration (electric corrosion resistance): Free of unsaturated bonds, preventing the deterioration of electrical properties due to oxidation and aging.

• Moderate elasticity and adhesion: Fills gaps at the adhesive interface, preventing moisture from entering through the gaps and maintaining long-term insulation

• Providing Flexibility and Stress relaxation

• Insulation reliability

• Adhesion reliability

• Heat resistance
