ODAKE CT8888 Biocompatible UV Adhesive: ISO 10993-5 Certified Medical Grade High-Toughness Shadowless Glue
In medical device manufacturing and food contact material processing, the biocompatibility and bonding reliability of adhesives are the most critical considerations. Catheters, masks, sensors — every product that comes into contact with the human body or food requires an adhesive that delivers both strong bonding and long-term safety without releasing harmful substances.
ODAKE CT8888 Biocompatible UV Adhesive is a professional-grade solution designed for these demanding applications. It is a medium viscosity, fast-curing, one-component UV curing adhesive that has passed ISO 10993-5 biocompatibility testing. It can be safely used in medical devices and food contact applications, offering excellent flexibility, impact resistance, and a wide temperature range (-54°C to 180°C).
1. What Is Biocompatible UV Adhesive?
A biocompatible UV adhesive is a UV-curable adhesive that has been validated through biological evaluation (such as ISO 10993-5 cytotoxicity testing) to have no cytotoxic effects on human tissue. It is primarily used in medical devices, food contact materials, wearable devices, and other applications with strict human safety requirements.
CT8888 is ISO 10993-5 certified and can be safely used in:
-
Medical catheters, masks, and sensor assemblies
-
Food contact grade transparent plastic bonding
-
Precision assembly of medical devices
