Formulation Note
The Shellflex 371 Extender Oil is added to improve the compatibility and reduce the melt viscosity of the Escorez 5280 Hydrocarbon Resin with the Kraton 1107 Thermoplastic Crumb Rubber. A better compromise between melt viscosity and pressure sensitive adhesive properties might be with less or no Shellflex 371 at all.
