question: When peeling off a sticker and trying not to leave any residue, why is it better to peel slowly?
comment: There is a huge amount of science behind pressure sensitive adhesive release. And, yes, if does involve "non Newtonian" behavior. Also, the backing sheets for bumper stickers and mailing labels have sophisticated release coatings (usually silicone based) that allow the " sticky" to last indefinitely in storage, but when you finally get that 2006 Prius you be been dreaming of, you can slap that "coexist" sticker without any worry about it falling off before the end of the second Trump administration. So, if you guys ever wonder what an industrial chemist does for a living, it's designing and optimizing stuff like this.
passages: Upon contact with water, the glue is loosened and the decal can be removed from its backing; overlong exposure, however, dissolves the glue completely causing the decal to fail to adhere.
  
  A "peel-and-stick" decal is actually not a decal as described above, but a vinyl sticker with adhesive backing, that can be transferred by peeling off its base. The sign industry calls these "peel-and-stick" vinyl stickers "vinyl-cut-decals".

   The method was pioneered by John Walton in 1928 as a method to derive serial thin-sections without the time, expense and lost material incurred by dissolving the rock. An improvement on the method, using gelatine (with glycerin and formalin) instead of cellulose, was reported in 1930, and is especially suitable for larger samples. This solution-based method was largely superseded by the use of pre-formed sheets of film, similar to those used in overhead transparencies; cellulose nitrate and cellulose acetate can be used, although the latter is preferable. By wetting the reverse surface of the film with acetate, the film becomes more labile and makes a better contact with the material. The peel can be washed in acid to remove any remaining matrix before mounting onto a slide with resin for further study. The method is somewhat destructive, as the acid etching used to remove the rock matrix can also destroy some finer detail; the fizzing caused by the reaction of the acid with the matrix breaks up less-robust cellular material. A second peel without further etching, a "rip peel", will remove any cell walls that are parallel to the surface, and would otherwise be destroyed when subjected to acid.
   In some situations, such as interior house paint, the orange peel texture is desirable. In this case, a texture paint is generally applied with a spray gun. The texture is then painted over with the appropriate color. When painting walls, orange peel can also develop by using a roller with too little paint or too thick a paint and the surface dries before the texture can level.

   BULLET::::- Peelable – Adhesion is fairly strong and will not fall off in normal circumstances, but the label can be removed relatively easily without tearing the base stock or leaving adhesive behind on the old surface. The adhesive is usually strong enough to be applied again elsewhere. This type is frequently known as 'removable'. There are many different types of removable adhesives, some are almost permanent, some are almost 'ultra peelable'.
   Some artists also use self-adhesive stickers as a quick way to do catch ups. While certain critics from within graffiti culture consider this lazy, stickers can be quite detailed in their own right and often, are used in conjunction with other materials. Sticker tags are commonly executed on blank postage stickers, as these can easily be acquired with no cost on the writer's part.
   Stick concealer is used for very specific purposes because it is thicker than liquid and contains a lot of coverage. This type of concealer is also very convenient because of the packaging and its ability to be used for touchups. This concealer works bets on blemishes and small areas of discoloration. Formulas that are very creamy, blend easily into the skin allowing for flawless touchups through the day.

   A peel's intended functions are to:
  
  BULLET::::- Transfer delicate breads, pastries, etc into an oven where transferring them directly by hand could deform their delicate structure.
  
  BULLET::::- Allow food to be placed further back in an oven than could normally be reached by the baker.
  
  BULLET::::- Keep the baker's hands out of the hottest part of an oven, or prevent the baker from burning their hands on the hot baked goods.
  
  Prior to use, peels are often sprinkled with flour, cornmeal, or milled wheat bran, to allow baked goods to easily slide onto and off them.
   BULLET::::- A glass plate is greased, and the smooth side of a peel pressed down onto it.
  
  BULLET::::- The rough side of this peel is covered with warmed (55 °C) epoxy resin, and pressed down onto the previously-prepared slide. After about 45 minutes the glass plate is removed, and the resin is left, warm, to cure.
  
  BULLET::::- The preparation is washed in acetone and acid to remove any residues, which would otherwise produce optical artefacts when imaged.
  
  Section::::Disadvantages.
   There are numerous designs of peelers used today. Most handheld peelers are either straight or Y-type, while the particular designs vary depending on region and personal preference.
  
  Section::::Straight peelers.
   BULLET::::- Ultra-peelable – Designed principally for use on book covers and glass, when removed these adhesives labels do not leave any residue whatsoever. Adhesion is weak and only suitable for light duty applications. Normally these labels have very little adhesion to anything once they've been removed.
  
  BULLET::::- Freezer or frost fix – Most permanent and peelable adhesives have a service temperature limit of -10 degrees Celsius, whereas freezer (otherwise known as frost fix) adhesives have a service temperature -40 degrees Celsius and are suitable for deep freeze use.
   Medium peels such as trichloroacetic acid (TCA) are also performed in the doctor’s office or in an ambulatory surgery center as an outpatient procedure and can cause more discomfort. Frequently, the combination of a tranquilizer such as diazepam and an oral analgesic is administered. TCA peels often do not require anesthesia even if the solution itself has - at the contrary of phenol - no numbing effect on the skin. The patient usually feels a warm or burning sensation.
   Peel strength with ion beam treatment increased as a function of the ion beam dose, achieving higher peel strengths than plasma-treated samples at doses above 5E15 ions/cm
  
  The primary effect of ion beam treatment therefore is morphology modification, with little chemical effect. Longer ion beam treatment time is assumed to increase surface area for bonding, which in turn increases peel strength.

   The coefficient of friction of banana peel on a linoleum surface was measured at just 0.07, about half that of lubricated metal on metal. Researchers attribute this to the crushing of the natural polysaccharide follicular gel, releasing a homogenous sol. This unsurprising finding was awarded the 2014 Ig Nobel Prize for physics.

   Section::::Surface preparation of plastics.:Peel ply.
  
  For a peel ply, a thin, woven piece of material is applied to the adherend during fabrication. Because the material is woven, it will leave a torturous surface when removed, which will improve bonding by mechanical interlocking. Prior to adhesive bonding, the woven material acts to protect the surface of the adherend from contaminates. When an adhesive is ready to be applied, the material can be peeled off, leaving a rough and clean surface for bonding.

   Filming started December. Tuggle said, "My hardest decision on the movie had to do with suspense. A comedy director has to choose between actually showing a man slip on a banana peel or concentrating on the anticipation, the knowledge that he's going to slip on it. The same thing happens in suspense."
   The deeper the peel, the more complications that can arise. Professional strength chemical peels are typically administered by certified dermatologists or licensed estheticians. Professional peels and lower-concentration DIY home peel kits can pose health risks, including injury and scarring of the skin. Possible complications include photosensitivity, prolonged erythema, pigmentary changes, milia, skin atrophy, and textural changes. Many individuals report professional chemical peels leave a minor yellowish tinge on their skin due to the retinol elements in the peel. This is expected to last 2–3 hours maximum. Varying mild to moderate redness after the procedure is expected.

   In general photography, this process is often referred to as pre-exposure or pre-flashing, and is used with both film and paper. It can provide greater control over lower values than simply decreasing the time the film spends in developer, as well as enhancing the response of paper to low values during printing.
   Baking cannot be used with acetate tapes, nor is it needed. Baking is also much less effective with u-matic tapes as the cases for those tapes prevent effective heat dispersion within the tape media.

   A creamed emulsion increases the likelihood of coalescence due to the close proximity of the globules in the cream. Factors that influence the rate of creaming are similar to those involved in the sedimentation rate of suspension particles, and are indicated by Stokes Law. 
   Gloss paint sprayed on a smooth surface (such as the body of a car) should also dry into a smooth surface. However, various factors can cause it to dry into a bumpy surface resembling the texture of an orange peel. The orange peel phenomenon can then be smoothed out with ultra-fine sandpaper, but it can be prevented altogether by changing the painting technique or the materials used. Orange peel is typically the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint. 
   Depending on the thickness and taste, fruit peel is sometimes eaten as part of the fruit, such as with apples. In some cases the peel is unpleasant or inedible, in which case it is removed and discarded, such as with bananas or grapefruits.
  
  The peel of some fruits — for example, pomegranates — is high in tannins and other polyphenols, and is employed in the production of dyes.
   The disentanglement of polymer chains is a kinetic process, and so the longer the die is, the more time is given for the physical entanglements within the polymer stream to disentangle. With a longer die and a slower polymer flow stream, less pronounced die swell will be observed. This is due to the longer die providing a longer time period for polymer, when subject to the increase flow rate, to disentangle. This characteristic relaxation time determines the length of time the polymer must spend inside the die to minimize die swell.
   People who opt to exhibit their individuality through these decals may take part in more acts of road rage. Colorado State University social psychologist, William Szlemko, found that aggressive driving is linked to the number of markers a person has on his/her car, regardless of the messages portrayed.
  
  Section::::Application and removal.
  
  Early bumper stickers had printed directions on the back removable liner for applying them to the bumper of a car. Due to the movement of the vehicle and changing weather conditions, the sticker needed to adhere well to the bumper surface.
   The effectiveness of stop, drop and roll may be further enhanced by combining it with other firefighting techniques, including the use of a fire extinguisher, dousing with water, or fire beating one's skin.
