Product Description
LOCTITE® 4013™ is a one-part, medium-viscosity ethyl cyanoacrylate adhesive formulated for rapid bonding of plastics and metals. Designed specifically for the assembly of disposable medical devices, the adhesive cures quickly at room temperature through exposure to ambient humidity and provides fast fixture times on a wide variety of substrates. LOCTITE 4013 has been evaluated using Henkel test protocols based on ISO 10993 biocompatibility standards, making it suitable for medical device manufacturing applications where dependable performance and rapid production throughput are required. The transparent adhesive delivers strong bonds, excellent handling characteristics and reliable mechanical performance after cure.
