Product Introduction
The initial tack tester operates on the inclined plane rolling ball principle. A specimen is adhered to the inclined plate, and the plate is adjusted to the specified angle. A standard steel ball is released from a defined position by the ball release device and rolls down the inclined plane. As it passes over the adhesive surface of the specimen, it is decelerated or stopped by the adhesion force. The initial tack is characterized by the largest steel ball number that can be held by the specimen. The device has a simple structure, is intuitive to operate, requires no power supply or complex setup, and is a classic standard instrument for evaluating the initial tack of adhesive products.

Main Technical Specifications 

FAQ 
1. What products is the Initial Tack Tester suitable for?
It is suitable for initial tack testing of various adhesive products, including pressure-sensitive tapes, medical patches, self-adhesive labels, and protective films.
2. What is the principle of initial tack testing?
It uses the inclined plane rolling ball method. The initial tack of the specimen is evaluated by the adhesion effect of the adhesive tape on a steel ball when brief contact occurs under slight pressure, characterized by the largest steel ball number that can be held.
3. How is the inclination angle adjusted?
The inclined plate angle is adjustable from 0 to 45°. Set the appropriate angle according to the applicable standard or testing requirements.
4. What specifications of standard steel balls are available?
Standard steel balls from 1/32 inch to 1 inch are provided, covering testing needs across different initial tack performance ranges.

5. How is test accuracy ensured?

The adjustable leveling base ensures the instrument is placed horizontally, the inclination angle is set accurately, the ball release position is standardized, and the testing environment should be clean and vibration-free.
6. Does the equipment require maintenance?
The purely mechanical structure requires only daily cleaning. Avoid contamination or rust on the inclined plate and steel ball surfaces.
