What is Multi-Applicator™?

The Multi-Applicator™ is designed to simultaneously test multiple coating thicknesses. The standard specification comes with three compartments to test three thicknesses (M3), and can also be made reversible to test six thicknesses (M6). The compartment size and numbers can be customized to fit the customer's needs. Its high precision, wire cut, single-piece structure makes it easy to use and clean. It can be used to coat by hand or on a test coater such as Mini-Labo™ (R2R Tabletop Test Coater), Mini-Labo Deluxe™ (R2R Lab Coater) and βCoater™ (Precision Sheet Coater).
