A double coated tape consist of a carrier that can be made of many materials but usually is a film or tissue. The adhesive is coated on both sides and covered by a two side silicone liner to allow for unwind.
These products offer the benefits of dimensional stability when laminated to extensible materials. They are also easier to slit and die-cut then transfer films. Two layers of adhesive also allow for using different adhesives on each side to bond surfaces that require different adhesive properties. Some applications include photo mounting, gasketing, splicing, product assembly applications requiring a permanent adhesive on one side and a removable the other.
