844 is a Clear Polyester film coated on both sides with a high performance, modified Acrylic Adhesive. This product comes with a dimensionally stable siliconized Red polypropylene release liner making it preferred for precision die-cut applications. The adhesive system of this double-coated tape is extremely aggressive, exhibits high shear strength, and will bond well to nearly all materials; even to difficult surfaces like foams, PE and PP films. It has excellent temperature, UV, aging, water vapor, and chemical resistance. Also has good plasticizer resistance.
