3M™ Double Coated Tape 444 is a 3.9 mil 300 high tack acrylic adhesive with a .5 mil polyester carrier on a 3.2 mil white 55 lb densified kraft paper liner. Use for foam lamination and gasket attachment. Good adhesion to most plastics. Thin polyester film carrier for dimensional stability and improved handling with ease of die-cutting and laminating. The high tack adhesive provides relatively high initial adhesion and good shear holding power to a variety of surfaces.

3M Double Coated Tapes are engineered with adhesive on both sides of paper, film or tissue. This increases the dimentional stability of the adhesive for easy handling and application.
