Viscosity

The right viscosity and the right viscosity curve ensure the optimum performance for your adhesive system. Tackifiers are the enabling raw materials to fine-tune for your viscosity requirements. Figure 1 represents the variety of viscosities that can be achieved for a given polymer system depending on the choice of tackifier. For a given temperature the viscosity can vary up to 5 times and more. The example shown uses SIS as the base polymer. Figure1: Influence of tackifiers choice on the viscosity of the adhesive
