HELMIPLAST 2526-2 is a flammable solventborne polyurethane cement used to bond various shoe materials such as leather, vinyl, urethane, rubbers, and most synthetic materials. It can also be used for direct injection molding of vinyl to cemented uppers. Used in conjunction with 5% HARDENER 505 for higher adhesive strength, increased heat resistance and improved adhesion, particularly to metal surfaces. Can also be cold-bonded as a contact adhesive while still in a semi-dry state.
