tesa® 7475 Silicon Coatings Charactersation Test Tape – Transparent – 25mm x 50m Roll
£79.24
- Purpose: Designed for the characterization of silicone coatings, particularly in the manufacture of release papers and films.
- Adhesive Type: Features a modified acrylic adhesive, which is essential for recording the interaction between silicone and acrylic adhesives.
- Backing Material: Made from PETP (Polyethylene Terephthalate) backing material, providing durability and stability.
- Liner Type: Utilizes a glassine liner, which aids in the easy application and removal of the tape.
- Testing Standards: Commonly used with FINAT 10 and FINAT 11 test methods to assess release properties and the degree of cure of silicone coatings.
- Comprehensive Characterization: For a thorough evaluation of release properties, it is recommended to use both tesa® 7475 (acrylic adhesive) and tesa® 7476 (natural rubber adhesive).
- Significant Adhesion: Provides significant adhesion even to easy-release silicone coatings, ensuring reproducible measurements.
- Long-Term Use: Successfully deployed for many years in assessing the release properties and curing of silicone coatings.
- Storage Conditions: Recommended to be stored at 23°C (73.4°F) and 50% relative humidity to maintain its properties.
- Shelf Life: Has a shelf life of 24 months from the date of manufacture when stored under recommended conditions.

Description
Product Features
tesa® 7475 and 7476 are especially designed for the characterisation of silicone coated liners. A typical test method represents FINAT 10 and FINAT 11.
For a comprehensive characterisation of release properties it is recommended to use both tapes.
tesa® 7475 features a typical modified acrylic adhesive to record the interaction of a silicone and an acrylic adhesive.
Additionally it shows a significant interaction with SiH Groups for measurement of the grade of curing of a silicone by measuring the subsequent adhesion according FINAT 11.
tesa® 7476 features a typical rubber adhesive to characterise the interaction between a silicone and a rubber adhesive. Both tapes feature a significant adhesion even to easy-release silicone coatings to provide reproducible measurements.
To characterise the test tapes themselves it is recommended to use their adhesion to steel.
Temperature Resistance
Long-Term Temperature Resistance
The tesa® 7475 test tape can withstand long-term exposure to temperatures up to 80°C. This makes it suitable for applications where the tape will be subjected to moderately high temperatures over extended periods.
Short-Term Temperature Resistance
For short-term applications, the tape can endure temperatures as high as 120°C. This higher resistance is beneficial for processes that involve brief exposure to elevated temperatures, such as certain manufacturing or testing procedures.
Freon-Proof Feature
The tape is also freon-proof, indicating its resilience to certain chemical exposures, which can be relevant in environments where temperature fluctuations are accompanied by chemical interactions.
Storage and Shelf Life
To maintain its properties, including temperature resistance, the tape should be stored at 23°C (73.4°F) and 50% relative humidity. Under these conditions, the tape has a shelf life of 24 months from the date of manufacture.
Conclusion
The tesa® 7475 test tape demonstrates robust temperature resistance, capable of withstanding long-term exposure to 80°C and short-term exposure to 120°C. Its freon-proof feature further enhances its suitability for various industrial applications. Proper storage conditions are essential to maintain these properties over its 24-month shelf life.
