Tape Coating Metering Rod

The coating metering rod controls the transfer amount of coating through grooves or patterns engraved on its surface. As the coating passes over the rod, excess coating is scraped off, and only the coating within the grooves is transferred to the substrate. It is used in laboratories to simulate the coating process and adjust coating thickness and uniformity. It is suitable for coating process testing of materials such as paper and films.
Selection
When selecting a metering rod for tape coating, considerations should include the surface characteristics of the substrate, the viscosity of the coating, and the desired coating thickness. Deep-grooved rods are suitable for rough substrates, while wide-grooved rods are recommended for high-viscosity coatings. The groove volume should be matched to the required coating thickness, and attention should also be paid to the chemical compatibility between the rod material and the coating. Stainless steel or chrome-plated steel rods are commonly used in laboratories.

Cross-cut tester combined with adhesion test tape for evaluating coating peel-off.
The cross-cut test, paired with adhesion test tape, is a commonly used method for evaluating coating adhesion. It involves using a cross-cut knife to score a grid pattern on the coating surface, followed by the rapid peeling of specialized tape. The adhesion level is then assessed by observing the extent of coating detachment.
Standard Procedure for Cross-Cut Test of Ink Adhesion
The cross-cut test is a standard method for testing ink adhesion. It involves cutting a grid pattern on the coated surface, applying and then peeling off adhesive tape, and observing the extent of ink peeling to evaluate the adhesion grade.
Application of Initial Tack Tester in the Adhesive Products Industry
The initial tack tester is used to measure the adhesive force of adhesive products upon initial contact, which is important for the research, development, and quality control of products such as tapes and labels. It simulates the process of materials making contact and then separating, records relevant data, and helps evaluate performance.
Tensile testing machine tests the tensile strength of industrial tape.
This article explains how to use a tensile testing machine to test the tensile strength of industrial tapes. Tensile strength is a key indicator for measuring the mechanical properties of tapes, and testing must comply with international standards such as ISO and ASTM.
The 180-degree peel strength test for tape shows a 50% deviation in data due to misalignment of the sample.
In the 180-degree peel strength test of adhesive tape, if the sample is misaligned, the test data may drop by about half. This is because misalignment causes uneven force distribution during peeling, reducing the effective peel strength.
