Reading Rheometer Graphs ② — Why Does the Gel Point Matter?
💡 In This Article What the gel point really means in a curing epoxy system How to interpret the G' / G'' crossover and when it can be used as a practical gel-point criterion Why the shape and slope of the curing curves can matter more than the gel time itself How gelation changes flow … Continue reading Reading Rheometer Graphs ② — Why Does the Gel Point Matter?
Reading Rheometer Graphs ① — Why Measure Viscosity Before and During Cure?
💡 In This Article Why a single viscosity value is not enough to describe an adhesive How shear rate connects rheometer data to real processing conditions How 3ITT can quantify thixotropic recovery What changes in rheological behavior matter when coating line speed increases An Adhesive Is Not a Solid Yet If you've been following this … Continue reading Reading Rheometer Graphs ① — Why Measure Viscosity Before and During Cure?
