피나트 FTM 9

Loop Tack Test Method

그만큼 루프 택 테스트 방법, standardized as 피나트 FTM 9, is a crucial procedure for evaluating the tackiness of pressure-sensitive adhesives (PSAs). Tack is one of the most vital properties of adhesives, particularly for applications involving labeling, tapes, and packaging materials. This test helps manufacturers and quality control professionals determine the adhesive’s initial grab, making it especially valuable in industries where fast adhesion is required.

What Is Loop Tack?

Loop tack refers to the force required to separate a loop of adhesive-coated material from a standard surface at a controlled speed. The test results indicate the ability of an adhesive to create an immediate bond with a substrate.

Test Procedure for FINAT FTM 9

Test Equipment and Conditions

To ensure reliable and repeatable results, the test is conducted using a 루프 택 테스터 with a vertical jaw separation rate of 300 mm per minute and an accuracy of ±2%. The standard surface used is a float glass plate, ensuring a uniform testing environment. The test is performed under controlled conditions of 23°C ± 2°C and 50% RH ± 5% RH to eliminate environmental influences.

Step-by-Step Loop Tack Test Process

1. 샘플 준비: A strip of adhesive-coated material (25mm wide, 175mm long) is cut from the test sample.
2. 루프 형성: The strip is formed into a loop with the adhesive facing outward and clamped into the upper jaw of the tensile tester.
3. Contact with Glass Plate: The loop is brought into contact with the glass plate at 300 mm per minute.
4. Separation Measurement: The machine immediately reverses direction to measure the force required to separate the loop from the glass surface.
5. 결과 기록: The peak force (loop tack value) is recorded in Newtons. If paper tearing (PT) or adhesive transfer (AT) occurs, it is noted in the results.

Factors Influencing Loop Tack Test Results

Several variables can affect the 루프 택 테스트 outcome:

• Adhesive Composition: Different adhesives exhibit varying tack properties.
• Backing Material Rigidity: Stiff materials may alter test results.
• Surface Cleanliness: The glass plate must be free from contaminants like grease or dust.
• 테스트 조건: Variations in temperature and humidity can impact adhesion behavior.

Why Traditional Methods Fall Short？

While older methods like the roll ball test (GB/T 4852-2002) are still used, they suffer from inconsistencies due to manual handling and environmental variables. The 루프 택 테스트 eliminates these issues by standardizing speed, pressure, and contact area, making it the preferred choice for global compliance.
