Description
TACKWHITE AP 26 is an acrylic water-borne pressure sensitive adhesive.
Due to its composition, it shows a very high cohesion, excellent wetting properties on different surfaces, an extreme transparency and an excellent water resistance, after curing.
Application
TACKWHITE AP 26 has been designed for the production of protective PE films. By adjusting the quantity of curing agent, it is possible to obtain products both for smooth and rough surfaces. The level of curing agent depends on the application of the final product: a higher amount of curing agent will allow to obtain a protective film for very smooth surfaces. TACKWHITE AP 26 is compatible with the traditional curing agents used for this kind of application, as isocyanates (Curing Agent W3 or Curing Agent W3 Dil) or polyaziridines (Curing Agent X7 or PZ-28).
The product can be coated with traditional coating systems, as Mayer bar, rotogravure, ...
