At first glance a self-adhesive product always seems straightforward, but it is so much more than just a mix of adhesives and substrates.
Innovating self adhesive tapes
Multifoil knows all about pressure sensitive tapes and the key factors that determine success or failure. With this knowlegde we engineer technical tapes for our customers. In many cases a bespoke product.
You might think that choosing a tape from the brochure by combining holding power and substrate is the way to go. It's not that simple.To give you an idea, an adhesive joint never stands on its own. Adhesives interact with the substrate and external factors such as temperature, daylight, moisture, chemicals, UV exposure, expansion and contraction are all factors that interact with each other and can make or break the bond.
Specialist and know-how of industrial tapes
Know-how and experience in these matters make a big difference and it has been our daily business for over 35 years. Multifoil operates totally independently of self-adhesive product manufacturers. This gives you the best possible guarantee that only the most suitable components are selected. In the past 35 years we have produced tailored solutions for the most diverse applications.

Adhesion and Cohesion
The internal strength of a pressure sensitive adhesive, also known as cohesion, plays an important role in the overall performance of the bond. Finetuning adhesives with this in mind is of the utmost importance.
Our on-site laboratory
In our industry we use specific research methods which are designed and standardized by renowned institutes such as PTSC, FINAT, DIN and BS. This allows us to conduct extensive on-site lab tests so you can be sure we are not comparing apples to oranges.
When we engineer an adhesive system for a new application, one of the criteria we check is physical stress between the two substrates to be bonded. After a freezing, clear night the sun hits the substrate in the morning. The expansion between the outer and inner part can be enormous and there is no room for guesswork or gut feelings. Measuring and testing the bond in the lab before implementing it is the way forward. To do this we have climate chambers with a range of -40°C to 200°C.
This research method measures how long it takes the tested self-adhesive material to break off and shows the strength of the tested material. The longer it takes, the greater the strength of the material. The method is as follows: the standard surface is usually a glass plate on which a strip of the tested material is coated with adhesive. A 1 kg weight is placed on the other side of the strip and the time it takes the strip to break off is measured.
