Abstract
A gelled solid adhesive for coating substrates, typically paper. The adhesive can be made available in stick form and is easily applied in even coats to any surface area of the substrate. The adhesive has sufficient tack enabling the coated substrate to instantly adhere to essentially any free contact surface upon gently pressing the substrate to the free surface. The adhesive coated substrate is easily removable from the contact surface by manually lifting it thereform. The adhesive permits readherence of the adhesive coated substrate to the same or different free contact surfaces. An adhesive coated paper substrate will readhere many times to free paper contact surface. The preferred gelled adhesive product is formed of an aqueous dispersion of components which include a rubber such as natural rubber latex component, a friction reducing agent, a tackifier, an antioxidant, a gelling agent and surfactant. Preferred classes of tackifiers are anionic aqueous dispersion of hydrogenated esters of rosin and anionic aqueous dispersion of esters of hydrogenated rosin.
