Masking tape Masking tape is a type of adhesive tape made with an easy-to-tear backing (usually paper) and a removable pressure sensitive adhesive. It is used mainly in painting, to mask off areas that should not be painted. The adhesive is the key element to its usefulness, as it allows the tape to be easily removed without leaving residue or damaging the surface to which it is applied. The tape is available in several strengths, rated on a 1–100 scale based on the strength of the adhesive. Most painting operations will require a tape in the 50 range. Household masking tape is made of an even weaker paper and lower grade adhesive.

Contents 1 History 2 Usage 3 Other types 4 External links [edit] History Masking tape was invented in 1925 by 3M employee Richard Drew. Drew observed auto-body workers growing frustrated when they removed butcher paper they had taped to cars they were painting. The strong adhesive on the tape peeled off some of the paint they had just applied. Touching up the damaged areas increased their costs. Drew realized the need for tape with a more gentle adhesive.

[edit] Usage For its original use of marking off areas where auto body paint is not desired, a special grade of painter's masking tape is needed. With this special grade, very clean lines can be produced. Without it, the paint bleeds under the edges of the tape, producing a fuzzy or varied line. Drafting tape looks similar to ordinary household masking tape, but has a lower tack. It is intended to hold blueprints to a drawing board or light table, and to pull off easily without damaging the drawing. Technical drawing, also known as drafting, is the practice of creating accurate representations of objects for technical, architectural and engineering needs. ... A light table is a viewing device that is used to review photographic film or artwork placed on top of it. ... House painter's tape is rated by how many days it can be left up without leaving residue on the surface being masked. It is available in 1, 3, 7, 14, 30, and 60-day ratings, with the 7 and 14-day tapes being the most common. The longer-rated tapes are typically less adhesive, and are sold for use on smooth, delicate surfaces such as vinyl wallpaper and recently painted walls. In any case, the tape should be removed immediately after painting regardless of how long it was left up beforehand. Painter's tape is often blue or purple in color as opposed to the tan household masking tape. [edit] Other types When constructed with polymer films instead of paper, masking tapes can be used for more rigorous applications. Polyester based tapes are used to mask off during etching, plating, and in particular, powder coating. Tapes based on polyimide films can resist molten solder in electronics applications. Glass cloth tapes are often used in powder coating and sandblasting operations. Foil or vinyl tapes are often used in plating. Layered tapes made from multiple materials laminated together can be used for masking flame spray, thermal spray and HVOF. A polymer (from Greek: πολυ, polu, many; and μέρος, meros, part) is a substance composed of molecules with large molecular mass composed of repeating structural units, or monomers, connected by covalent chemical bonds. ...

High Velocity Oxygen Fuel (HVOF) is a technique to deposit thin films on a material, and can be used to deposit layers as thick as 12mm (1/2).

The adhesive applied to a tape is often a critical determining factor for a given masking situation. There are three broad types of adhesives (with many chemical variations of each): rubber-based, acrylic-based, and silicone-based. Rubber based adhesives generally provide the greatest adhesion, but the lowest temperature resistance. Acrylic-based adhesives offer a wide temperature range, providing adhesion from sub-freezing temperatures up to 275–325° Fahrenheit (about 150° Celsius). Silicone based adhesives provide the highest temperature resistance, with some tapes (such as some polyimide films and glass cloth tapes) allowing for intermittent use up to 500°F (260°C).
