YSHIELD® PSA is an aqueous, low-emission, acrylate-based adhesive for the production of permanently self-adhesive layers. With an sd-value of 0.02 m, it is highly permeable to water vapor for diffusion-open bonding on walls, ceilings and floors.
 
Coverage / Application
Coverage: 5 sqm/l for single-layer application.
PSA can be applied like a wall paint with a paint roller. The thicker the layer, the stronger the adhesive strength. With wet bonding, work quickly and on small areas, then corrections can still be made. With dry bonding, you have an immediate, very strong adhesion that can no longer be removed. It is best to work with a squeegee, which allows materials to be applied evenly and smoothly to the wet or dry adhesive layer. Our K150, with an aluminum layer , is difficult to bond on the aluminum side, and typical wallpaper pastes do not adhere well. PSA has no problem, due to the combination of tack and permanent tack. Due to the high tack (initial tack), the materials adhere very well even when the adhesive is still wet. If edges or corners become detached during drying, they can simply be pressed back on with the squeegee due to the permanent tack.
 
Never wash out the paint roller, wrap it in airtight plastic film or bag for storage, allow to dry and dispose of at the end of the job.
