Details

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.

Seals Out Moisture, Dust and Drafts
3M™ Urethane Foam Tape 4104 is 1/4 in. thick, 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.

Recommended Applications


Cushion and dampen sound in electronics such as printers, keyboards, computers, aircraft lights and automotive dashboards
Recessed lighting
Door, window and cabinet seals


Excellent Shear Holding Strength with 3M™ Adhesive 350
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°F (93°C) in the short term and 350°F (176°C) long term. 

Protect Sensitive Components
The adhesion of 3M™ Single-Coated Foam Tapes is typically satisfactory within 20 minutes 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. 

What is Open Cell Foam?
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
