Square Frame Preparator

The square frame applicator uses a metal frame to spread paint evenly on a substrate, forming a wet film of uniform thickness. It is used in laboratories to simulate the coating process and test properties such as paint leveling and hiding power. It is commonly employed in quality control within the ink and paint industries.
Selection
When selecting, consider matching the frame material with the substrate type, determine the frame gap size based on coating thickness requirements, let the operating environment dictate the corrosion resistance of stainless steel or aluminum alloy, and choose between manual or automatic models to suit the laboratory throughput.

Film applicator standardized preparation of test samples.
The film applicator is a crucial tool in fields such as coatings and inks for preparing test samples, ensuring uniform thickness and a smooth surface through standardized operations. The article introduces its scraping-based working principle and the selection between manual and automatic types.
Coating film preparation techniques: comparison between wire-wound applicators and wet film preparators
This article compares two commonly used tools in laboratory coating film preparation: the wire rod coater and the wet film applicator.
The importance of maintaining a constant speed when using a wet film applicator for coating.
When using a wet film applicator, maintaining a constant speed during the scraping process is crucial for coating uniformity. The scraping speed directly affects the wet film thickness, and fluctuations in speed can lead to defects such as streaks and uneven thickness, compromising the repeatability and accuracy of experimental results.
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.
