Product Introduction
Cemedine SX720B is a black, single-component elastic adhesive formulated with a special silyl-group polymer, making it ideal for electrical and electronic assemblies. This adhesive cures easily at room temperature, providing rapid bonding, excellent mechanical strength, and superior electrical insulation. It also features high thermal conductivity for effective heat dissipation. Engineered with safety and environmental compliance in mind, SX720B is free from halogens, low molecular weight siloxane, and other harmful substances. Its balanced properties of flexibility, strength, and insulation make it a reliable choice for high-performance sealing and fixing tasks.
Cemedine SX720B Features
- Simple Application: One-part adhesive system cures at ambient temperature and humidity.
- Efficient Processing: Black paste consistency with a tack-free time of 10 minutes.
- Elastic Bonding: Moderate viscosity of 45 Pa·s and Shore A hardness of 78 make it ideal for flexible bonds.
- Strong Adhesion: Delivers high tensile shear strength of 3.4 N/mm² for a secure bond.
- Excellent Flexibility: A 100% breaking extension allows it to absorb vibration and thermal stress.
- Thermal Performance: Features high thermal conductivity of 1.09 W/m·K and a glass transition point of -63°C.
- Reliable Insulation: Offers high volume resistivity of 2.3×10¹² Ω·cm.
- Environmentally Compliant: Halogen-free and does not contain antimony oxide or phosphorus-based compounds.
- Contamination-Free: Free from low molecular weight siloxane compounds (D3–D10).
Cemedine SX720B Applications
- Bonding and fixation of electronic components such as capacitors and coils on circuit boards.
- Sealing of transformers and power units to improve insulation and durability.
- Waterproofing of electronics to protect against moisture, dust, and environmental exposure.
