3M 4318
Single Coated Foam Tape

General Information

A 125.0 mil. urethane tape, series 4310, featuring a A-30 acrylic adhesive on a thick silicone treated liner used for lighting, door, window and cabinet sealing applications. 4318 is a grey, conformable low-density, open-cell foam tape with a pressure-sensitive acrylic adhesive coated on one side. The adhesive is protected by a thick silicone liner. 4318 tape belongs to the 4310 urethane tape series which is a very soft, conformable, low-density foam helping seal out air, dust and light when compressed 50%. Extra care should be taken when handling these delicate rolls of tape to avoid damaging the tape. 4318 adheres to a variety of substrates, including latex painted wood, lacquered wood, enameled steel, glass, aluminum, stainless steel, acrylic, ABS and PVC (non-plasticized). The tape adhesion is typically satisfactory within 20 minutes and continues to build with additional time. The solvent/ fuel resistance test consists of visual observation of tape bonded to steel panels and immersed totally in solvent/ fuel for 24 hours.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.

Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
