ABSTRACT:
A standardized test for measuring the stringiness of room temperature vulcanizable silicone sealant compositions is disclosed wherein a tube of sealant is held at a constant angle to the surface upon which the sealant is being applied. The surface is movable and once a small bead of sealant has been deposited upon the surface the surface is moved at a constant rate of speed until the sealant bead breaks off from the source. The length of any string of sealant formed thereby is measured. This measurement for a given composition is compared to the measurement for other compositions and thereby allows optimization of sealant compositions to minimize an undesirable feature.
