Applicable Base Polymer Properties
Natural rubber is generally available as a light brown, slightly viscous solvent solution. It has poor elevated temperature resistance without vulcanization. It has good resistance to water and to mold, but poor resistance to oil, solvents, and low temperatures.
Solvent based natural rubber adhesives are based on solutions of the solid rubber in solvents such as toluene, naphtha, and trichloroethane. Generally solvent-based natural rubber adhesives have a solids content of 10-25%.
