tesa® 7475 Test tapes for the characterisation of silicone coatings 

• 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.
• tesa® 7475 has been successfully deployed for many years, both when it
• comes to assessing the release properties of silicone coatings (FINAT 10 or similar)
• and testing the curing of silicone coatings (FINAT 11 or similar).
• For a comprehensive characterization of release properties it is recommended to
• use both tesa® 7475 (acrylic adhesive) and tesa® 7476 (natural rubber adhesive).
• It is recommended to store tesa® 7475 at 23 °C and 50 % relative humidity.
• Backing material PETP
• Type of adhesive acrylic
• Type of liner glassine
