3M™ 7000122494 Single Coated Tape, 18 yd L x 3/4 in W, 250 mil THK, Acrylic Adhesive, Urethane Foam Backing, Natural

3M™ urethane foam tape 4104 is a firm, high density, open cell foam tape with a pressure sensitive acrylic adhesive on one side. This tape will adhere to a variety of substrates and can be used in numerous applications to dampen sound and create a clean and durable product. 3M™ urethane foam tape 4104 is 1/4 in THK, comprised of a firm, high density, open cell foam with a pressure sensitive acrylic adhesive on one side. The adhesive is protected by a silicone treated paper liner. It offers excellent cushioning characteristics while allowing air or gas vapors to pass through, while providing high absorbency to seal out moisture, dust and drafts. It can perform under a wide range of temperatures. Special note - 3M™ urethane foam tape 4104 may turn yellow when exposed to light, only affecting its appearance and not physical performance. 3M™ urethane foam tape 4104 features 3M™ adhesive 350. This pressure sensitive, modified acrylic adhesive provides high initial quick stick to a variety of surfaces and substrates. It has an excellent chemical resistant and shear holding strength, even at elevated temperatures. Adhesive 350 is designed to perform at temperatures up to 200 deg F (93 deg C) in the short term and 350 deg F (176 deg C) long term. The adhesion of 3M™ single-coated foam tapes is typically satisfactory within 20 min and continues to build with additional time. The adhesive is protected by a thick, silicone treated paper liner and has a firm, high density foam. This design offers an attractive and clean appearance after application. Open cell foams are commonly used between component panels where a degree of separation is needed to dampen or prevent vibration, as a thermal insulation barrier and to protect against contamination, but where a measure of airflow is still necessary, such as with electronic components where air flow helps keeps components cool.
