The industrial gel instant adhesive 3M Scotch-Weld SIGel is primarily designed for bonding natural materials with a higher surface pH, such as wood, leather, fiberboard materials, cork, etc. Thanks to its gel viscosity, it better fills the irregularities of bonded surfaces of porous materials. Does not drip. Technical parameters system:cyanoacrylate base:ethyl hybrid cyanoacrylate temperature resistance:80 °C UV resistance:very good moisture resistance:good chemical resistance:very good application:application nozzle of the glue bottle
