DOWSIL SILASCON RTV 7500 W/C is a medical-grade silicone sealant built for precision industrial uses. It comes as a transparent liquid, cures fast at room temperature (20-30 minutes tack-free), has Shore A hardness of 50, tensile strength >5 MPa, elongation ≥300%, and stays stable from -40°C to 200°C (short-term 250°C). Certified by ISO 10993 and FDA 21 CFR 175.300, it performs well in medical device sealing and automotive engine compartments, offering >4 N/mm² adhesion to glass, metals, and ABS plastics for better reliability.
Medical-Grade Compliance: Holds ISO 10993 and FDA certifications, enabling direct tissue contact in medical scenarios.
Broad Temperature Tolerance: Maintains stable performance under 121°C/30min steam sterilization and freezing conditions.
Strong Mechanical Performance: 5 MPa tensile strength and 300% elongation prevent deformation during use.
Medical Devices: Used for ventilator sealing and surgical tool potting, meeting GB 9706.1-2020 standards.
Automotive: Applied in engine wire sealing and sensor waterproofing to protect automotive components.
Electronics: Serves as PCB conformal coating, providing moisture protection for electronic circuits.
Construction: Used for structural glazing joints, featuring UV resistance to endure outdoor environmental impacts.
