Low Viscosity, One Part Cyanoacrylate
Master Bond MB250NT is widely used for a variety of applications ranging from repair to high speed production for disposable/reusable medical devices and passes ISO 10993-5 testing requirements. It also resists EtO and gamma sterilization processes.
This single component ethyl cyanoacrylate cures rapidly depending upon the atmospheric humidity—the higher the level, the faster the rate of cure. There is no mixing or heating required for curing. Since the cure is usually fast, only minimal contact pressure is required for bonding. MB250NT will typically set up within 10-40 seconds. It has a low viscosity of 100-110 cps.
Featuring high tensile laps shear strength values, MB250NT bonds well to a variety of substrates especially metals, composites, most plastics and rubbers. The service temperature range for this system is -60°F to +250°F. It has a shelf life of about 6 months in its original, unopened containers.
