Method for determining rheological characteristics at particular unhardened adhesive sample, involves introducing adhesive composition in free-flowing state between two nonstick mold plates, and compressing mold plates

摘要

#CMT# #/CMT# The method involves introducing an adhesive composition (1) in a free-flowing state between two nonstick mold plates (2), and compressing the mold plates while reducing the distance to a predetermined adhesive thickness. The thick calibrated adhesive composition is frozen in unhardened condition in a dimensionally stable manner and is demolded. The calibrated adhesive composition is measured as a calibrated adhesive sample in a characteristic value-testing device and is directly heated before starting the measuring process from the frozen condition to test temperature. #CMT#USE : #/CMT# Method for determining rheological characteristics at a specific unhardened adhesive sample. #CMT#ADVANTAGE : #/CMT# The calibrated adhesive composition is measured as a calibrated adhesive sample in a characteristic value-testing device and is directly heated before starting the measuring process from the frozen condition to test temperature, and thus ensures accurate testing measurement of the calibrated adhesive sample through the rheological characteristic determining method in a simple manner, where the formation of condensate on the adhesive composition is prevented. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an unhardened adhesive composition applied to a nonstick mold plate. 1 : Adhesive composition 2 : Nonstick mold plates 3 : Spacers.
