The QUICKTEST 38^® and the RAPIDTEST 38^® can be used to determine to what extent the pretreatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect.The liquid contained in the pen remains as a continuous line at a surface tension value of 38 mN/m or greater, below that it rolls off. The line applied with QUICKTEST 38^® or RAPIDTEST 38^® dries in a matter of seconds and no longer needs to be wiped off.

ATTENTION: The test liquid of QUICKTEST 38^® and RAPIDTEST 38^® contains solvents. Solvent-sensitive materials (e.g. PS) can be attacked by this, which can lead to misinterpretation!
