LAT-01 Lasting Adhesiveness Tester

Introduction of Tape Holding Power Tester

The Tape Holding Power Tester is an essential testing instrument designed to measure the adhesion strength of pressure-sensitive tapes and labels under constant load conditions. It assesses the ability of adhesive tapes to resist slippage and maintain their bond when subjected to stress, making it a crucial tool for industries that rely on adhesive tape performance, such as packaging, medical, pharmaceuticals, and more.

This tester provides a reliable means to evaluate the long-term stability and durability of tapes, ensuring that they adhere to the required standards for various applications. It is used to determine how well tapes stay adhered to surfaces, even under challenging conditions, offering vital insights into their performance over time.

Tape Holding Power Tester Application

The Tape Holding Power Tester is commonly used in the following industries:

• Packaging: Ensures that tapes used in packaging materials maintain their adhesive properties during transport and storage.
• Medical and Pharmaceutical: Verifies the adhesive strength of medical tapes, bandages, and pharmaceutical packaging materials.
• Adhesives: Essential for testing the performance of pressure-sensitive adhesives used in labels, tapes, and other adhesive-based products.
• Textiles: Helps assess the adhesion of textile tapes and labels under stress conditions.
• Quality Inspection Agencies: Provides objective data on tape performance, aiding in quality control for manufacturers and suppliers.

It is primarily used to test the holding power of pressure-sensitive tapes and labels to ensure they meet the necessary specifications for real-world applications.

Test Principle

The Tape Holding Power Tester operates on the principle of shear adhesion under constant load. The test involves the following process:

• A strip of tape is applied to a standard steel panel under controlled conditions.
• A standard mass is attached to the free end of the tape to apply a constant load.
• The panel is then positioned vertically, and the time taken for the tape to fail (i.e., slippage or complete detachment from the surface) is recorded.

This test helps simulate real-world conditions where tapes may be subjected to forces that could lead to adhesive failure. The Tape Holding Power Tester is capable of testing various types of pressure-sensitive tapes, including those used in industrial, medical, and consumer applications.

Test Methods

ASTM D3654

The ASTM D3654 standard is one of the most widely recognized methods for testing the shear adhesion of pressure-sensitive tapes. According to ASTM D3654:

• The tape is applied to a standard steel panel and subjected to a constant mass at a specified angle.
• The tester measures the time to failure or the amount of slippage that occurs as the tape is subjected to constant shear stress.
• This method evaluates the ability of the adhesive to resist sliding under stress, providing a quantitative measure of the holding power.

PSTC-107

The PSTC-107 is another critical industry standard for testing the holding power of pressure-sensitive tapes. This standard specifies how to measure the ability of tapes to withstand forces applied parallel to the adhesive surface, which mimics conditions seen during actual use.

• Like ASTM D3654, PSTC-107 assesses the time to failure or the amount of slippage that occurs when a specific mass is applied.
• It ensures that tapes used in various products maintain their adhesive properties under constant load conditions over time.

Both ASTM D3654 and PSTC-107 are essential standards for ensuring the performance and reliability of pressure-sensitive adhesives.
