Dyne Test Pens
For testing the surface tension
To determine the cleanliness of surfaces
Test Inks can make statements on the adhesive strength of printing inks, coatings and adhesives on all surfaces such as plastic, metal and glass as well as on the degree of cleanliness in dyne/cm (mN/m).
Dyne Test Pens PINK
Pink coloured Dyne Test Inks are special testing liquids in ranges of defined surface tension. They were developed to get “non-poisonous” Test Inks.
These pink Dyne Test Inks meant to substitue the blue coloured inks as they were declared to be toxic according to DIN 53364 / ISO 8296.
The Test Pens PINK are available
from 22 to 60 dyne/cm
• with accuracy +/- 1 dyne/cm
• observation time :
22 – 26 dyne/cm: 2 seconds
28 – 44 dyne/cm: 4 seconds
45 – 60 dyne/cm: 2 seconds
• simple handling
• no spilling
Pen sets available in sets
of 4, 6 and 8 pcs. or as single pens
QUICKTEST 38®
Quicktest 38® serves to check if the treatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect onto the material.
A stroke of the pen leaves a full line on the material if the material´s surface tension has a value of 38 mN/m or more. If the material´s surface tension is below 38 mN/m, the fluid contained in the pen will form small drops on the surface. The fluid applied to the surface will dry within seconds, it doesn´t need to be wiped off anymore.
• extremely easy to handle
• perfect for quick checks on polyolefins
• no wiping off necessary
• lasting display of result
• archiving of the image possible
• good readability due to striking red discoloration
• content: 5 ml
Application of the Test Pens
Apply the test ink as a line to the clean, dry surface. Observe the behaviour of the ink within the specified time: if it runs evenly without contracting, the surface energy is at least equal to the value of the ink used. If the line contracts or forms drops, the surface energy is below the specified value.
Service
Expert advice, guarantee of the specified values, reliable and punctual delivery, cooperation with our customers at home and abroad are our priorities.
Quality Assurance
For quality assurance, the inks are tested using a state-of-the-art contact angle measuring device, taking temperature and density into account. Safety data sheets provide information on handling, storage and transport regulations.
