Laboratory stainless steel wire Rods

Laboratory stainless steel wire rods are metal bars wound with a specific diameter of steel wire on the surface. By immersing them in the coating material and pulling them up at a constant speed, they form a fixed wet film thickness on the test substrate. They are used for controlling coating thickness and evaluating uniformity in paints and inks, and are combined with dry film measurements to calculate parameters such as hiding power and saturation.
Selection
When selecting, consider the wire diameter specification corresponding to the required wet film thickness, choose 304 or 316 stainless steel for corrosion resistance, ensure the wire winding is uniform and without gaps, check that the handle is ergonomic for comfortable grip, match the length to the dimensions of common substrates, and use a matching wire rod cleaner and storage rack to extend service life.
