Key FeaturesExperimental Doctor Blade Automatic Small Testing Coating Machine
How to use
Place the applicator on a perfectly flat test surface. Adjust the squeegee so that the required gap is twice the amount of wet film thickness required.
In front of the applicator, pour a small amount of test sample onto the end plate at a slow, even rate of about 1-2 cm per second.
Move the instrument over the surface until all of the liquid has been applied and or any remaining liquid has been removed from the end of the coating path.
The exact ratio of wet film thickness to any coater gap depends on the material used, the viscosity and texture of the liquid.
The actual wet film to be applied should be adjusted to your desired thickness using a thickness gauge to adjust the gap.
Frequently Asked Questions
How do I determine the initial gap setting for the squeegee?
You should adjust the squeegee so that the gap is set to twice the amount of the target wet film thickness you require for your test.
What is the correct speed for pouring the test sample?
Pour the test sample slowly and evenly onto the end plate at a rate of approximately 1 to 2 cm per second to ensure uniform application.
When should I stop moving the applicator instrument?
Continue moving the instrument until all the liquid sample has been applied, or until any excess liquid is cleared from the end of the coating path.
Does the wet film thickness always equal exactly half of the coater gap?
No, the exact ratio is not always fixed. It depends on several variables including the specific material used, its viscosity, and the texture of the liquid.
How do I ensure the applied film matches my exact target thickness?
You should measure the actual applied wet film using a thickness gauge, and then fine-tune the squeegee gap based on those measurements to reach your desired thickness.
