Abstract
A rosin composition includes a gum rosin, an emulsifier, a randomizing additive and a bonding agent. This rosin composition may be used as a temporary or permanent adhesive for the soldering of components. The rosin composition may be temporary as it is easily removed from a surface without damaging the surface.
