Dynamic Absorption Tester

Dynamic Absorption Tester

Introduction

Contact angle measurement is an empirical tool for understanding the wetting between a liquid and a substrate. The DAT Dynamic Absorption Tester offers a range of integrated instruments, for research as well as quality control. These instruments enable real-time, automatic analysis at full video speed of the interaction between a liquid droplet and a specimen surface. The time-dependent wetting and liquid penetration correlates to many experienced production problems in surface coating, sizing, printing and adhesion.
