The 3M™ Double Coated Tape 444 features the 3M™ Adhesive 300, a medium-firm, acrylic adhesive ideal for joining materials that are smooth, thin and have low residual stress. It is excellent for foams and LSE plastics such as polyethylene, as well as HSE plastics.Excellent for textured plastics, foams, fabrics and coated papers, the 3M Double Coated Tape 444 features the 3M Adhesive 300 on a 0.5 mil (0.01 mm) 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 mil (0.4 mm) on the liner side and 2 mil (0.05 mm) on the face side for effective wet out. The 55# densified kraft paper release liner makes for fast, efficient application. The 3M Adhesive 300 is a medium firm, acrylic adhesive system featuring both high initial adhesion and good UV and chemical resistance and strong holding power. The design of the adhesive results in high initial adhesion and good temperature performance. The formulation gives the 3M Adhesive 300 a consistently strong bond across a range of temperatures up to 250F/121C short term. 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.
