Product descriptiontesa® 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.
