Abstract (en)
[origin: WO2020157541A1] A liquid adhesive coating composition that cures into a solid form, used to non- permanently adhere interior floor or wall coverings to substrate floor or wall surfaces respectively, includes a polymer incorporating iron or other paramagnetic,superparamagnetic, ferromagnetic, or ferrimagnetic ingredients, that becomes permanently adhered to the substrate as it cures, and thereafter provides a low- tack adhesive surface that is also magnetically attractive, upon which magnetized floor or wall coverings including certain types of carpet, linoleum, vinyl, wallpaper, and other types of magnetically- backed coverings can be subsequently installed. The combined low-tack adhesive and magnetic adhesion qualities of the cured composition of the invention allow for the magnetically-backed floor or wall coverings to be sufficiently well adhered to the surface of the cured adhesive composition to remain in place during normal usage while retaining the ability for the coverings to be subsequently removed, repositioned or replaced without damaging the respective coverings, adhesive coating composition layer, or substrate.
