Manufacturing Partner:
Erichsen Model 494 washability tester is used for the testing of the washing, brushing and scrubbing resistance as well as cleanability of dispersion paints. Adjustable parameters of the machine cycle allows for customized testing such as testing using cleaning agent and solutions. Also a wide range of accessories are available to enhance testing.
Design of washability tester:
- Steel top cover plate for testing
- High precision stepper motor, which is operated by micro controller device
- Three parallel Abrasion tests can be done by the machine
Washability Tester – Result of test can be determined by:
- Number of cycles needed to remove a film completely
- Amount of film material (weight) removed per unit of tested surface and per cycle.
Frequently Asked Questions
A washability tester is a device that allows the user to understand by how much the coating on a substrate has degraded by repeated scrubbing (simulated by a back and forth movement) over a specified distance repeatedly.
Washability testers are used by the glass and the automotive industries.
