Glue and Adhesives

There are literally THOUSANDS of glues, so a question like this is impossible. Please Name your Glue and you will get a good answer.

Generally, a glue can be labeled non-toxic if it contains no volatile organic compounds (VOC). VOCs are gases or vapours emitted by various solids or liquids that may be in glue, many of which have short- and long-term adverse health effects. VOCs are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. A wide range of carbon-based molecules, such as aldehydes, ketones, and other light hydrocarbons are VOCs. The term often is used in a legal or regulatory context and in such cases the precise definition is a matter of law. These definitions can be contradictory and may contain "loopholes"; e.g. exceptions, exemptions, and exclusions. The United States Environmental Protection Agency (EPA) defines a VOC as any organic compound that participates in a photoreaction; others believe this definition is very broad and vague as organics that are not volatile in the sense that they vaporize under normal conditions can be considered volatile by this EPA definition. The term may refer both to well characterized organic compounds and to mixtures of variable composition.

E1 is a rating of the amount of formaldehyde present. The measurements are obtained by using the Perforator Test Method. Here are the ratings:

E0 <= .5 mg of formaldehyde per 100 g of dry board.

E1 > .5 mg and <= 9 mg of formaldehyde per 100 g of dry board.

E2 > 9 mg and <= 30mg of formaldehyde per 100 g of dry board.

E3 > 30 mg per 100 g of formaldehyde per 100 g of dry board.

I read in Readers Digest a long time ago that it was a Native American saying about snow conditions but I remember it as "sticky no sticky no sticky sticky". And meaning if the snow is sticky and can be made into a snowball it won't be around long, and if it is not sticky, not able to be made into a snowball, it will be around for awhile.

To glue papers together, apply a thin, even layer of glue along the edge of one paper. Press the two papers together firmly and hold in place for a few seconds to allow the glue to dry. Make sure to use a glue that is suitable for paper and won't cause wrinkling or clumping.

Tapioca is a starch used in the Food and Beveridge Industries. It is found in Bread, wheat and rice noodles, condiments and canned foods. Ice Cream needs starch and a strengthening agent. There are many applications in the textile and timber industries. As a starch it is water based, so your glue may be diluted by adding small amounts of liquid until the correct consistency is obtained. Warm the water a little, it may help

To remove adhesive from Plexiglas, you can try using rubbing alcohol or acetone on a soft cloth and gently rubbing the adhesive. You can also try using a plastic scraper to carefully scrape off the adhesive, being cautious not to scratch the Plexiglas. Additionally, using a commercial adhesive remover specifically designed for plastics may also help loosen and remove the adhesive.

Diphenylmethane is a chemical compound consisting of two phenyl groups attached to a methane backbone. It is used as an intermediate in the production of various organic compounds and polymers. Diphenylmethane can also act as a heat transfer fluid at high temperatures.

You can make a simple flubber without flour or glue by mixing together 2 parts cornstarch to 1 part water. Add food coloring for color, and you can also add glitter for some extra sparkle. This mixture will create a stretchy, fun material similar to flubber.

Sticky notes are typically made from paper that has been treated with a special adhesive coating on one side. The adhesive is usually a repositionable, pressure-sensitive acrylic adhesive that allows the note to stick to surfaces without leaving residue when removed. Some environmentally-friendly options may use recycled or sustainably-sourced paper and adhesives.

Hypothesis: By mixing together polyvinyl alcohol (PVA) and borax solution, a non-Newtonian fluid known as slime can be created.

Statement on making slime: Mix equal parts of PVA glue and borax solution together in a bowl until the desired consistency is achieved, then knead the mixture with your hands until it becomes slime-like in texture. Experiment with different ratios to achieve the desired slime consistency.

Adhesive tape typically consists of a backing material (such as paper, plastic, or fabric) coated with an adhesive substance to allow it to stick to surfaces. The adhesive can vary depending on the type of tape, but common components include rubber, acrylic, or silicone. Sometimes, additional additives such as tackifiers or stabilizers may be included in the formulation.

my friend told me that you'll get slime or goo

When glue is frozen, its chemical bonds can weaken or break, altering its adhesive properties. This can cause the glue to become brittle or lose its ability to adhere properly. It's best to store glue at room temperature to maintain its effectiveness.

Casein glue is water-based, non-toxic, and dries to a strong, durable bond. It is heat resistant and has good adhesion to porous materials like wood, paper, and fabric. However, it is not water-resistant and can be affected by high humidity.

Gluons! Although it depends what you mean by particle. In a hadron (like a proton or neutron) the 3 quarks which make it up are held together by the strong nuclear force which is mediated (or transferred) by gluons.

In an atom the protons and neutrons are also held together by the strong force but it is much weaker than within the nucleon.

Yes, sticky is an adjective used to describe things that adhere to surfaces. Glue is a type of adhesive substance that makes things sticky, so in that sense, sticky can be considered an analogy for glue.

You can certainly die from drinking glue, but in most cases you would vomit before you got a fatally toxic amount of glue into you. You have to recognize that "glue" covers a very wide range of adhesives that have a wide variety of components. Glue made from old horse hooves will probably make you puke long before you could eat enough to kill you. Trying to drink the components of superglue (cyanoacrylate based adhesive) would cause significant damage to the esophagus to the point of potentially causing fatal bleeding. A bigger risk would be fatal asthma from the fumes. Many glues contain very toxic solvents which can kill a person on their own. Certainly if a person aspirated some of the glue when they were drinking it, they could choke to death on it.

You can tell if glue is dried by checking if it feels hard and no longer tacky to the touch. If the glue has a transparent or opaque appearance, it likely has dried completely. Additionally, if there is no odor coming from the glue, it is also a sign that it has dried.

Glue typically comes in a liquid or solid form. Liquid glue is often white and viscous, while solid glue can vary in color and form, such as glue sticks or glue dots. Once applied and dried, glue creates a clear, sticky bond between surfaces.

To remove water soluble glue from cement, try soaking the area with warm, soapy water and scrubbing gently with a brush. You can also use a mixture of vinegar and water, or a commercial adhesive remover following the product instructions. Rinse the area thoroughly once the glue has been removed.

To change the color of liquid glue, you should add food coloring.

To glue two pieces of cork together, use a strong adhesive such as E6000 or a contact cement. Apply the adhesive to both surfaces, press the pieces together firmly, and allow the glue to dry according to the manufacturer's instructions. Clamp the pieces together if necessary to ensure a secure bond.
