LOCTITE® 431

Features and Benefits

This instant adhesive is ideal for difficult-to-bond materials such as porous and acidic materials. Also used in the assembly of disposable medical devices.
LOCTITE® 431 is a medium viscosity (medical device grade) instant adhesive designed especially for the fast bonding of plastics and rubbers. By 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 Henkel's ISO 10993 protocols for use in disposable medical devices.
