Product Introduction
Cemedine SX720BH is a black, high-hardness, one-component adhesive featuring a silyl-group polymer base, designed for robust electronic assembly. It cures quickly under ambient conditions, providing excellent adhesion, thermal stability, and reliable electrical insulation without the need for mixing. With its high viscosity, it is ideal for vertical or gap-filling applications. This adhesive ensures superior performance in demanding industrial environments due to its strong mechanical properties and resistance to moisture and heat. SX720BH is also environmentally responsible, formulated to be free from halogens, low molecular weight siloxane, and other hazardous substances.
Cemedine SX720BH Features
- One-Component Formula: Cures at room temperature and humidity, eliminating the need for mixing.
- Fast & Efficient: Features a quick tack-free time of 8 minutes and a high viscosity of 85 Pa·s for efficient application.
- High Hardness: Offers strong mechanical rigidity with a Shore A hardness of 82 and a breaking strength of 3.2 N/mm².
- Durable Flexibility: Provides moderate flexibility with 50% elongation to withstand mechanical stress.
- Thermally Stable: Performs reliably in extreme conditions, with a glass transition point of -69°C.
- Excellent Electrical Insulation: Ensures reliable performance with a high volume resistivity of 1.4×10¹² Ω·cm.
- Environmentally Safe: Free of halogen-based substances, antimony oxide, and phosphorus-based compounds.
- Clean Formulation: Does not contain low molecular weight siloxane (D3–D10), preventing contact failure in electronics.
Cemedine SX720BH Applications
- Fixing and sealing of circuit board components such as capacitors and inductors.
- Sealing transformers and power modules for insulation, strength, and environmental resistance.
- Moisture-proof sealing of electronic parts in environments requiring higher mechanical rigidity.
