SmartDrop-E or SmartDrop-F test inks : guidelines for the right choice
AcXys Technologies has released two types of inks: SmartDrop-E and SmartDrop-F. Their characteristics apply to specific situations and a deeper look at these various features will guide you to the right product. Both our products comply with applicable standards and regulations (ASTM D2578-09 for SmartDrop-E and ISO 8296 : 2003 for SmartDrop-F). Moreover, they are super reliable and provide trustworthy results thanks to a very strict manufacturing process that guarantees their maximal stability.
What type of material are you measuring?
PP: polypropylene, PMMA: Polymethyl methacrylate (Plexiglas), PTFE: Polytetrafluoroethylene or Teflon, PVC: Polyvinyl chloride.
If you are planning to use SmartDrop test inks on materials compatible with SmartDrop-E, this should be your first choice. SmartDrop-E is made of water, ethanol and dye. It is a non-toxic ink. SmartDrop-F has a degree of toxicity because it contains water, 2-ethoxyethanol, formamide and dye. It can be used on any material. The value range of SmartDrop-E is larger (22 to 72 mN/m) than SmartDrop-F (28 to 72mN/m).
The material colour to be tested can also influence the choice of the test ink to be applied: SmartDrop-E ink shines with a bright neon yellow, highly visible on dark backgrounds. SmartDrop-F has a deep blue shade, we can only recommend to use it on (for example) a PET yellow background – the results of your surface energy measurement will not be missed!
