The technical name for the adhesive backing is Transparent Solvent Polyacrylate which basically translates to an adhesive that has great sticking power. The self-stick is ready to attach itself to your glass window. The adhesive sticks so well you can roll your window up and down and it will not stick or peel off. In addition, the self-stick adhesive is easily removable without leaving any residue (see Q & A for details).
