3M VHB 4943F DOUBLE SIDED ADHESIVE CIRCLES, GRAY, 1.500”  DIAMETER, SOLD BY THE CIRCLE

3M VHB 4943F DESCRIPTION

3M 4943F is a double-sided, gray, acrylic foam tape that is 0.045” thick (1.1 mm). It has a Very High Bond (VHB) that can bond even at very low temperatures. Its acrylic adhesive composition makes it well suited for a variety of substrates. 3M VHB 4943F is highly conformable, so it provides a more uniform seal on irregular surfaces. The fast and easy to use permanent bonding method provides high strength and long-term durability. It offers design flexibility with its viscoelasticity and powerful ability to bond to a variety of high, medium and low surface energy substrates.

Yes, 3M adhesive products are indeed expensive. You’re paying for quality, reliability and all the research that went into developing a particular tape for a specific application. Buying a full roll of 3M VHB 4943F shouldn’t require cashing in your 401K. We sell 3M VHB 4943F by the piece so you can buy just what you need.

** During Resistance Tests, 3M VHB 4943F was taped between stainless steel and aluminum foil and then Immersed in solvents for 72 hours. Continuous submersion in chemical solutions is not recommended. It is presented to show that occasional chemical contact should not be detrimental to tape performance in most applications during ordinary use.

3M VHB 4943F THERMAL EXPANSION & CONTRACTION

3M VHB Tapes can perform well in applications where two bonded surfaces may expand and contract differentially. Assuming good adhesion to the substrates, the tapes can typically tolerate differential movement in the shear plane up to 3 times their thickness.

3M VHB 4943F BOND FLEXIBILITY

While an advantage for many applications where allowing differential movement is a benefit, the tape bonds are typically more flexible than alternative bonding methods. Suitable design modifications or periodic use of rigid fasteners or adhesives may be needed if additional stiffness is required.

3M VHB 4943F PERFORMANCE IN SEVERE COLD

Applications which require performance at severe cold temperatures must be thoroughly evaluated by the user if the intended use will subject the tape product to high impact stresses. Read the 3M technical bulletin “3M VHB Tape Cold Temperature Performance” for additional information.
