Abstract
A method of making a contact adhesive includes the steps of mixing a solvent with a rubber blend and/or resin for making a contact adhesive and then processing the solvent/rubber/resin blend until a desired lowered viscosity is reached while obtaining a solids content of greater than 30 weight percent. The contact adhesive has a viscosity capable of allowing atomization of an adhesive which contains a solids content of greater than 30 weight percent.
