4926
3M VHBT 15mil Gray Conformable Acrylic Foam



General Information
3M 4926 is a 15 mil, VHBT double-coated, conformable acrylic foam. 4926 is the main product when conformability is necessary. 4926 utilizes multi-purpose acrylic adhesive on both sides of a conformable foam. It has excellent adhesion to a broad range of high and medium surface energy substrates including metals, glass and a wide variety of plastics and plasticized vinyl. In many cases 4926 can replace rivets, spot welds, liquid adhesives or other permanent fasteners.

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.


Choose the surface energy of the exact surface that the adhesive will contact (e.g. if the part was painted metal, paint would be the surface energy).
