The Jiaoshuilao JSL 401 is formulated specifically for wood, paper, and metal substrates where standard super glues may not provide optimal adhesion. Its medium viscosity (110mpa.s) allows for controlled application on porous surfaces like wood grain and paper fibres, penetrating just enough to create a strong mechanical bond without soaking through. With a 15-second initial cure and full strength in 24 hours, it is a reliable choice for woodworking repairs, paper craft assembly, and metal component bonding.
