1.Britain imported sherman corona pen2.accurate testing result
SHERMAN DYNE PEN :32-72 dyn/cm common dyne:38/40/42/44
usage: when testing, for example, using 38dyn/cm pen to scribe a long line slightly on the treating materials , after two seconds, if ther is no glob formed ,or does not spread all around, it means the surfac tension reached or exceed 38dyn/cm , in contrast , if a glob formed, it means the surface tension can not reach 38dyn/cm In general, the first test for accuracy and measurement, to be prepared with 4 different types of dyne pen; if the film surface tension value changes little, you need at least 3 different types of dyne pen.
