Overview
A.shine Type 72 Dyne pen is a professional tool for testing the surface tension of materials. It can accurately test whether the surface tension of Plastic film reaches the test pen value, help users determine whether the material is suitable for printing, compounding or vacuum aluminizing processes, effectively control the mass and reduce the loss caused by the material failure.
Features
1. Built-in 15ml test solution, can be used more than 100 times
2. Shelf life is 6-8 months
3. The pen tip is carefully designed to reduce the chance of contact between dyne liquid and air
4. Each pen has undergone multiple inspections and the quality is guaranteed
Principle
Dyne pen uses the nib to scribe the test liquid on the surface of the material and observe whether the liquid cissing within 3 seconds to determine whether the surface tension of the material reaches the selected Dyne Level. If the liquid has no cissing, it meets the standard, otherwise it does not meet the standard.
Applications
Plastic film: PS, PE, PP, PET, PI, PC, NY, CPP, OPP, PVC, conductive materials: aluminum foil, copper foil, carbon foil, vapor coating, Miscellaneous materials: Glass, ceramics, plastic sheet, plastic pipe
Standards
ASTM Standard D2578、TAPPI T698
Steps
1. Choose the right Dyne Level corona pen
2. Clean the film surface and lay it flat on a horizontal table
3. Use a corona pen to stroke lightly on the film surface
4. Observe whether the liquid cissing within three seconds: if there is no cissing, the selected dyne will be reached, otherwise it will not be reached
Notice
• Avoid skin/eye contact
• Avoid inhaling vapors, mists or gases
Keep away from heat and ignition sources
• The valid period is 6 months from the date of opening
