3M Scotch 226 Solvent Resistant Masking Tape
Our converter's current 1" inventory of 3M 226 is a few years old and no longer within its 1-yr shelf life so it's currently on sale. Once that inventory runs out price will revert back to its regular price.

Nominal Tape Widths vs Actual Widths
Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:
- 1" Nominal width = 15/16" (24mm) Actual width
- 2" Nominal width = 1-7/8" (48mm) Actual width
- 3" Nominal width = 2-13/16" (72mm) Actual width
Note that tape rolls are NOT guaranteed to be splice-free.
3M Scotch 226 Solvent Resistant Masking Tape is a black polyethylene film reinforced with a saturated crepe paper used for outdoor masking applications as well as hot air leveling of printed circuit boards. Other uses include sealing, holding, bundling, reinforcing, identifying, tabbing, wrapping, paint masking, splicing and protecting. The polyethylene backing is resistant to many solvents, water solutions and emulsions and paint strippers of both the wax-base type and the mild caustic solution solvent-emulsion type. The tape offers several features and benefits such as its heavy thickness crepe paper backing is good for paint lines; its natural rubber adhesive offers good instant adhesion; and it is an easy tear, pressure sensitive tape which is conformable. It also offers clean removal properties on most opaque surfaces for up to three months of outdoor exposure and its saturated crepe paper layer reinforces the tape to control stretch. Industries the tape can be used in include transportation, aerospace, automotive, commercial vehicle, RV, bus, truck, ship yards, military, metal working, furniture, electronics, solar, trailer manufacturing and woodworking.

hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
