A Double Coated Tape for Foams and LSE Plastics

Excellent for textured plastics, foams, fabrics and coated papers, 3M™ Double Coated Tape 444 features 3M™ Adhesive 300 on a 0.5 mil polyester (PET) film carrier. The medium-firm acrylic adhesive delivers high initial and final adhesion for efficient laminating procedures. The durable polyester film carrier between the adhesive layers improves the handling and strength of the tape, and adds stability during processes such as die-cutting and slitting. The adhesive is applied at 1.4 mils on the liner side and 2 mils on the face side for effective wet-out. The 55# densified kraft paper release liner makes for fast, efficient application.

What is Double Coated Tape?

In general, double coated tape is composed of a paper, film, or tissue carrier that is coated on both sides with pressure sensitive adhesive. The adhesive is protected by a peel-away liner that is removed at the time of application. These tapes can be applied by hand or with a dispenser. Double coated tape dispensers are available in a variety of configurations ranging from manual to fully automatic. Applications for double coated tape are found in electronics, automotive, aerospace, general industrial, and fabrication markets.
