In order to address unique adhesive challenges, we developed 3M™ Scotch-Weld™ Surface Insensitive Instant Adhesive SI1500. This is a high viscosity instant adhesive that bonds rough, porous, contaminated and acidic substrates including wood, cardboard, veneer, fabric, cork and leather. This “instant glue” is ideal for filling small gaps and its rapid cure time helps keep processes moving forward
