WindowTac Permanent/Removable Double Sided Mounting Adhesive

Turn any print into a window decal with WindowTac! WindowTac is a clear, 1mil, PET film, with a permanent adhesive on one side and an air egress removable adhesive on the other. It enables easy, bubble-free face mounting of large solid graphics to glass with the aid of a squeegee.

It is coated on one side with a removable aqueous adhesive, which is protected by a micro-grooved polyethylene release liner that imparts an embossed pattern onto the adhesive coating. The other side is coated with a permanent aqueous adhesive that is protected by a Kraft release paper.The film contains UV stabilizers which protects against UV degradation.

For optimal results, this product is not to be combined with perforated window products as it is not optically clear. This mounting adhesive is designed for use on solid materials no thicker than 8mil thick.
