Single-hand line bar

A single-hand wire-wound rod is a coating tool used to evenly spread paint on a substrate surface by manually pulling a stainless steel rod, forming a wet film of a specific thickness. Its principle relies on the grooves wound around the rod to control the amount of coating material. It is suitable for small-scale coating tests in laboratories, uniformity evaluation of ink printing, and preparation of paper coatings.
Selection
When selecting, consider the substrate roughness to match the wire-wound gap, choose the corresponding model based on the target wet film thickness, and opt for stainless steel material, which is suitable for most solvent-based coatings. Maintain a constant speed while pulling to avoid shaking. Narrow-width wire-wound bars are suitable for small samples, and clean the grooves with solvent promptly after use to prevent clogging.

The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
