Selecting the best catalyst
A catalyst determines many of the final properties of a STYCAST system. It's selection is as important as that of the resin as it has a significant influence on final cured hardness, mixed viscosity, temperature capabilities and physical properties.
Understanding viscosity
Viscosity is the measure of the internal resistance of friction when a material moves against itself. It is typically measured using a rotating spindle instrument (viscometer). The amount of force required to turn the spindle (torque) at a selected speed (rpm) is measured. A simple calculation converts this internal resistance to viscosity. Thicker materials equates to higher torque values, hence, higher viscosities.
