431 Surface Insensitive Gap Filling Instant Adhesive

LOCTITE® 431 is a medium viscosity (medical device grade) adhesive designed especially for the fast bonding of plastics and rubbers. Using primer LOCTITE® SF 7701, the assembly of difficult-to-bond materials (PP, PE, PTFE) is possible. It has a fixture time of 15 seconds and is well-suited for porous and/or acidic surfaces. LOCTITE® 431 is tested to ISO 10993 protocols for use in disposable medical devices.
