This product is designed for laboratory-scale preparation of uniform wet films in coating and material research. The four-sided fixed film applicator ensures consistent layer thickness across the substrate, with selectable coating depths ranging from 5 µm to 1000 µm in various step combinations (e.g., 100/150/200/250 µm or 25/50/75/100 µm). Its 80 mm wet film width accommodates standard substrate sizes commonly used in battery electrode coating, adhesive testing, or functional thin-film development. The durable construction and fixed-edge design minimize edge effects, making it suitable for reproducible drawdown applications in materials science laboratories. This applicator supports precise control over film thickness, enabling researchers to systematically evaluate coating performance, drying behavior, or layer property variations across multiple experimental conditions.
