Bondloc - B401 Medium Viscosity Cyanoacrylate 20g - BONB40120
Bondloc B401 is a medium viscosity Cyanoacrylate. It bonds metals, plastics, wood, ceramics, rubber, leather, card, glass and many other materials.
Cyanoacrylate adhesives cure through reaction with moisture held on the surface to be bonded. They need close fitting joints and usually solidify in seconds which has resulted in the universal generic name of 'superglues'. Curing is started the by film of moisture found on most surfaces which is usually slightly alkaline and it is this alkalinity which causes the polymerisation.
Most grades have varying viscosities and therefore they need close fitting joints. Newer developments of gelled variants allow cure in wider gaps and application to vertical surfaces. Cyanoacrylates are suited to small plastic parts and to rubber bonding.
