Adhesive

Adhesive (pronounced ad-hee-siv or ad-hee-ziv)

(1) Something coated with glue, paste, mastic, or other sticky substance (which may be intended for either temporary or permanent purposes); a substance that causes something to adhere, as glue or rubber cement.

(2) Figuratively, tenacious or clinging.

(3) Sticking fast; sticky; apt or tending to adhere; clinging.

(4) In physics, of or relating to the molecular force that exists in the area of contact between unlike bodies and that acts to unite them.

(5) The quality or degree of stickiness in the physical sense; relating to adhesion.

(6) In philately, a postage stamp with a gummed back, as distinguished from one embossed or printed on an envelope or card.

1660s: The adjective meaning “sticky, cleaving or clinging” was from the French adhésif, from the Latin adhaesivus, from adhaereō (supine adhaesum). The French construct was formed from the Latin adhaes-, past-participle stem of adhaerere (stick to), the source also of adherent.  The noun was derived from the adjective and emerged in 1881, original as a descriptor of postage stamps (as a clipping of the original (1840) adhesive stamp, the word later adopted in philately as a technical distinction between the classic stick-on stamps and other types.  Around the turn of the twentieth century, it was used in the general sense of "a substance that causes to adhere", as a point of differentiation from simple glue.  The spelling adhæsive is obsolete.

Because of the use in engineering, science, industry & commerce, adhesive is a popular modifier, the forms including adhesive capsulitis, adhesive tape, hot melt adhesive, self-adhesive, adhesive bra, adhesive bandage, adhesive binding, adhesive plaster & adhesive tape.  Words related to adhesive (in the physical or figurative sense depending on context) sense include gummy, sticky, adherent, holding, hugging, pasty, adhering, agglutinant, attaching, clinging, clingy, gelatinous, glutinous, gooey, gummed, mucilaginous, resinous, tenacious, viscid & viscous.  Adhesive is a noun & adjective, adhesion is a noun, adhesively is an adverb and adhesiveness is a noun; the noun plural is adhesives.

Very Abstract

Piet Mondrian’s (1872-1944) 1941 New York City 1 is an abstract piece created with multi-colored adhesive tape.  First exhibited at New York’s Museum of Modern Art (MOMA) in 1945 and hung since 1980 in the Düsseldorf Museum as part of the Kunstsammlung Nordrhein-Westfalen’s collection, recently it was revealed for the past 77 years it has been hanging upside down.  The work is unsigned, sometimes an indication the artist deemed it unfinished but Mondrian left no notes.

The decades-long, trans-Atlantic mistake came to light during a press conference held to announce the Kunstsammlung’s new Mondrian exhibition.  During research for the show, a photograph of Mondrian’s studio taken shortly after his death showed the work oriented in the opposite direction and this is being treated as proof of the artist’s intension although experts say the placement of the adhesive tape on the unsigned painting also suggests the piece was hung upside down.  How the error occurred is unclear but when first displayed at MOMA, it may have been as simple as the packing-crate being overturned or misleading instructions being given to the staff.  However, 1941 New York City 1 will remain upside because of the condition of the adhesive strips.  “The adhesive tapes are already extremely loose and hanging by a thread,” a curator was quoted as saying, adding that if it were now to be turned-over, “…gravity would pull it into another direction.  And it’s now part of the work’s story.”

The curator made the point that as hung, the interlacing lattice of red, yellow, black and blue adhesive tapes thicken towards the bottom, suggesting a sparser skyline but that “…the thickening of the grid should be at the top, like a dark sky” and another of Mondrian’s creations in a similar vein (the oil on canvas New York City I (1942)) hangs in the Musée National d’Art Moderne in Paris with the thickening of lines at the top.  Whether Mondrian intended 1941 New York City 1 to be part of his oeuvre or it was just a mock-up in adhesive tape for the oil-on canvas composition to follow isn’t known, artists having many reasons for leaving works unsigned.

Conventional "backless" bras.

The term "backless bra" can be misleading in that most of them aren't actually built without a back-strap; rather the strap is engineered in a variety of ways to sit well below the shoulder-blades, usually somewhere around the lower back.  Often that's enough to suit the outfit with which it's being paired but sometimes there's a need to expose the whole back and here an adhesive bra can be the solution.  Adhesive bras (single-use and re-usable and sometimes called "stick-on bras" or "stickies") are specialized devices which have a large part of the surface-area facing the skin coated with a medical-grade adhesive.  Made usually from silicone or polyurethane and available in a variety of designs (in one and two-piece configurations), almost all are strapless or backless and the variations in design exist to accommodate the different clothes under which the bra will be worn.  One chooses one’s adhesive bra cognizant of the dress or top to be worn, the idea being that once dressed, only skin should be visible.  In cases where no commercial available adhesive bra is quite right, a variety of medical-grade tapes (sold as tit-tape, skin-tape, boob-tape et al) are available including double-sided versions which can hold the fabric of clothes in place.  These have the advantage of being able to be rendered in whatever shape is required but can be difficult to apply single-handedly although boyfriends and girlfriends should be anxious to assist.  Experts suggest avoiding the cheapest on the market because some of there are not medical grade and there's the risk of minor skin damage and consequent infection.

For those (regardless of size) who don’t require lift and need only to minimize lateral movement, the two-piece units (which can use a central coupling depending on the outfit) are ideal because they are available in versions with a smaller surface area, some of which use a higher percentage of the adhesive material to adhere to skin below the bust-line which can be helpful.  These are essentially a modern variation of the pasties (adhesive patches worn over the nipples by exotic dancers) from the late 1950s with some structural engineering added to enhance support.

Most two-piece adhesive bras are a pair of stand-alone units but some offer the option of centre-adjustments.  The methods vary, some using Velcro, the familiar hook & eye combination or buckles but the most popular type use shoe-lace style ties.  The scope of adjustment offered is not only lateral (forcing the flesh towards the centre) but also vertical (forcing the flesh upwards), both movements enhancing cleavage and this permits the same bra to be used for more than one style of outfit.

Although mostly associated with backless and strapless styles, adhesive bras are also available which accommodate plunging necklines.  The two-piece units allow designers to display a cut to the waist but more modest renditions, optimized for cleavage, use a kind of cantilever, usually called the “plunge”.

Adhesive bras use rather than defy the laws of physics and there are limits to the volumes which can be accommodated.  As a general principle, as the movable mass (and in this case there’s not always a direct correlation between weight and volume) increases, the surface area of the adhesive material which adheres to skin above the effective centre of gravity (essentially the pivot point) should increase.  That means larger sizes can be handled for backless dresses and even plunges are possible but it won’t be possible always to display the skin on the upper poles and designs required to secure a greater mass can be less comfortable because they often include some variation of an underwire to guarantee structural integrity.  As with all forms of structural engineering (essentially making push equal pull), the physics involved means there are limits to what can be done.
