3Extreme Sealing Tape4412N

Product Description 3M™ Extreme Sealing Tape 4412N is a single coated, pressure sensitive adhesivetape designed for difficult sealing applications. The backing on this tape is anionomer film that is very tough yet flexible and abrasion resistant. The very soft and thick acrylic adhesive has excellent sealing properties and good long term,outdoor durability. This single coated tape is designed to seal over an existing joint,seam, or penetration. The adhesive is designed to adhere well to the ionomer film sothat overlap layers of this tape can be used and still provide a tight seam to itself andthe joint or seam to be sealed.

ApplicationGuidelines

Depending on the surfaces to be sealed, one of three basic surface preparations will berequired:

1) Good cleaning with a 50:50 mixture of isopropyl alcohol* and water toremove contaminants;

2) Fine abrading with a 180x grit or finer abrasive followed by good cleaningwith a 50:50 mixture of isopropyl alcohol* and water; or

3) Good cleaning with a 50:50 mixture of isopropyl alcohol* and waterfollowed by application of an adhesion promoter or primer.

Ideal tape application is accomplished when temperature is between 70° and 100°F (21° and 38°C) and the bond is allowed to dwell 24 hours. Tape application to surfacesat temperatures below 50°F (10°C) is generally not recommended. Once properlyapplied, low temperature holding is generally satisfactory.

With the protective release liner still attached to the tape, apply tape by hand using lighthand pressure. Using a soft roller, such as a medium nap paint roller, apply mediumpressure to conform tape on contours, seam edges, rivets, or screw heads. Peel off theprotective release liner. To optimize adherence and conformance to uneven surfaces, afinal tape roll down should be done.

*Note: Consult manufacturer’s directions for use and precautions when using cleaningsolvents. This cleaning recommendation may not be compliant with the rules ofcertain Air Quality Management Districts in California; consult applicablerules before use.

3M 4412N Peel Strengths on Many Surfaces TSR # IATD-4871; RGK 08-39; prepared by R.G. Koza on January 6, 2009

Application Description: The 4412N tape (aka EST, Extreme Sealing Tape, or single coated Beta tape) is a very thick, very tacky, single coated tape that has many potential uses for a wide variety of sealing applications. As a single coated tape, the sealing is done by “oversealing” an existing joint or penetration, as opposed to “between surface sealing” applications done with a double coated tape, gasket, or liquid sealant/adhesive. One specific, intended use for this tape is “roof-to-trim” sealing on commercial vehicles to eliminate large quantities of liquid sealants. Purpose of Test: To determine the ninety degree peel adhesion strength of this 3M 4412N tape to a wide variety of surfaces using up to four surface preparations. Some of this data will likely be used in technical data sheets for 4412N tape. Test sample preparation: The only tape tested was 3M 4412N; lot #NR26T02B manufactured in Japan with stock #JT-2700-6005-9. This tape was 1” wide x 4” long x 2mm (.080”) thick. This tape is translucent white. It has a clear, matte finish, 2 mil thick, relatively non-stretchy, polyester release liner “attached” to the non-adhesive, top side of the ionomer film. Samples were prepared as described in TSR #IATD-4870 test report with anodized aluminum peel strips attached to the non-adhesive side of the ionomer film of the 4412N with 3M VHB™ tape 5925 (25 mils thick). The 4412N tape roll down to the test substrate was accomplished with a total of two passes under a 15 pound roller traveling at 12 inches per minute. Approximately 300 ninety degree peel adhesion tests were run at room temperature. The four surface preparations used on the various test substrates, prior to 4412N tape application, were:

1) “Clean only” with a 50:50 mixture of isopropyl alcohol and water. 2) “Fine abrade” was done with a 3M Scotchbrite™ 7447 pad in an electric, palm held, finishing

sander. After the fine abrading, cleaning was done with a 50:50 mixture of isopropyl alcohol and water.

3) “AP111”; Test surfaces were first cleaned with a 50:50 mixture of isopropyl alcohol and water and then primed with 3M Adhesion Promoter 111 using a disposable facial tissue. Solvent in this adhesion promoter is isopropyl alcohol.

4) “P94”; Test surfaces were first cleaned with a 50:50 mixture of isopropyl alcohol and water and then primed with 3M Primer 94 using a disposable facial tissue. The primary solvent in 3M Primer 94 is cyclohexane. The 3M Primer 94 was allowed to dry approximately 2 minutes prior to tape application.

5) “AP115”; only surface tested with 3M Silane Glass Treatment AP115 was glass. AP115 was sprayed on the glass surface and wiped dry with a disposable facial tissue. The primary solvent in 3M AP115 is isopropyl alcohol with some water and a very small amount of silane.

Tape was applied at room temperature (~70 degF), allowed to dwell at room temp for 24 hours, and tested at room temp with crosshead speed at 12 inches per minute in mid-December, 2008.

Summary and Comments: It appears that the ninety degree “adhesive split” (aka “foam split”) value for 4412N tape (at 12 inches per minute peel speed with a non-stretchy anodized aluminum peel strip) is about 20-21 pounds per inch width of tape. This “adhesive split” occurs when the adhesive strength of the tape to the test substrate and peel strip is greater than the cohesive strength of the thick adhesive/foam of the 4412N. Some reasonable peel adhesion strengths were achieved with the “clean only” surface preparation on many of these 31 different test substrates. However, the use of Adhesion Promoter 111 on most metals and painted surfaces and the use of Primer 94 on many plastics greatly increased the peel adhesion strengths. On many test substrates, fine abrading also showed some significant improvements in peel adhesion strengths. Although not a surprise, adhesion to the polyolefins (LDPE, HDPE, UHMWPE, and PP) was generally poor with little to no improvement with either Adhesion Promoter 111 or Primer 94. This 4412N tape appears to be soft enough, and therefore conformable enough, to adhere equally well on both the bumpy side and smooth side of the very popular Kemlite® brand FRP roofing materials. Adhesion to all of the tested bare or treated metals seemed to be about the same. Please call if you have questions or if I can help further.
