This resins series are stabilized low colour penta esters of gum rosin. Main applications are hot melt adhesives and PSAs.
In this series, resins promote different melt viscosities, open time and service temperature on hot melt adhesives made with them. As a rule, adhesives made with penta esters are higher in melt viscosity, tensile strength and service temperature compared to glycerol esters.
Our products are high softening point resins used in adhesives requiring good flexibility, no embitlement and high tensile strength. The main use for those resins is the production of wood assembly hot melt adhesives.
Penta esters can be used in other industries like road marking paints.
