Seals Out Moisture Dust and Drafts3M Urethane Foam Tape 4116 is 1/16 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 4116 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 3503M Urethane Foam Tape 4116 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 200F 93C in the short term and350F 176C 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 air flow helps keeps components cool.
