Choosing Adhesive
Introduction
Why need different adhesive layers?
We offer the option to choose a different adhesive layers in order to cover as much as possible of customer requirements. Although each of the tree adhesive types has good adhesion properties and resistance, they are different in details.
FTM 2
FINAT is the European association for the self-adhesive label industry.
FINAT Test Method 2 – Peel adhesion (90°) at 300mm per minute. Test method to quantify the performance of adhesion or peelability of self-adhesive (pressure sensitive) materials.
SP Standard Permanent Adhesive
Standard Permanent Adhesive is an acrylic dispersion with excellent clarity, UV-stability and water resistance with limited adhesion at low temperatures and on corrugated surfaces.
Area of use
Standard Permanent adhesive type covers almost 95% of application areas. After doming stickers are applied, the process of adhesion will continue over time and actually the adhesion strength will increase over years. Doming stickers with Standard Permanent adhesive are suitable for use on flat and smooth surfaces. The most common applications are for branding household appliances, electronics, sports equipment, POS displays, business cards, custom packaging, keyholders and many more…

Conclusion
From our experience through the years, we can say that Doming stickers with Standard permanent adhesive will meet a huge range of applications both for indoor or outdoor use.
Because it’s hard to test the adhesion of stickers on all possible surfaces, it’s highly recommended requesting a Free Sample pack before placing an order especially when doming stickers should be applied on surfaces or in conditions out of the ordinary use.
