Abstract

A synthetic material comprises a base material providing at least one tacky surface that is tacky at a temperature of less than about 80.degree. C.; and a powder layered upon the base material which has a substantially non-tacky surface at a temperature of up to about 40.degree. C. and exhibits adhesiveness at a temperature of greater than 120.degree. C. The powder includes one or more correspondence components such as an epoxy resin which is either i) substantially identical to a component of the base material, or ii) the monomer or oligomer configuration of the correspondence component is substantially identical to a component of the base material but may have a greater molecular weight or longer polymer chain structure, or iii) is insubstatantially different from a component of the base material (e.g. has the same characteristics and a similar structure but a higher molecular weight).
