Glue and Adhesives
Glue or adhesive is a liquid or semi-liquid mixture that bonds items together. It can be natural or synthetic, one part or two part, the latest development or an ancient recipe that still works. This is the place for glue/adhesive questions, such as - how to use it successfully, what it's made of, or how to get it out of your hair!

What chemicals give glue its smell?
Glue typically contains chemicals such as formaldehyde, acetone, and toluene which can give it its strong and distinct smell. These chemicals can evaporate into the air and create the odor that is often associated with glue.
How does temperature affect the strength of glue?
um.. I'm pretty sure that strength of glue is weakened when in heat, because the glue melts instead of hardens. When doing so the glue is unable to stick the two objects together. =]
ANS 2 - This depends on the kind of glue. Most epoxies recommend heat, and I've definitely found that gentle heating of both parts before mixing lets them mix easier and creates a much stronger joint.
How do you remove tacky glue from clothes?
To remove tacky glue from clothes, you can try placing the garment in the freezer for a few hours to harden the glue, then carefully scrape it off with a butter knife or similar tool. You can also try applying a small amount of rubbing alcohol or acetone to the affected area and gently rubbing it off with a cloth. Test a small, inconspicuous area first to ensure the fabric is not damaged.
How do you trim a sheet of Lexan plastic?
They say to score it with a razor and then snap it along the line but I used to make plaques out of plexi and I found that a slow speed jigsaw with a wood blade will allow you to make corners or shapes without fracturing the plastic. Just start off really slow with the blade barely moving and once the cut is started you can speed it up a bit but never full speed as the plastic will just melt.
I took two 2x4x8 and placed them on edge, spaced them 1/2" apart and used two pieces of scrap wood on the ends to keep them evenly spaced using sheet rock screws. The line on the lexan that I wanted to cut goes directly above this space between the 2x4x8. I then made my cut using a jig saw with a wood blade. As stated before make your cut slowly. Mine came out fantastic.
What are the thin sheets glues together to make plywood called?
The thin sheets glued together to make plywood are called veneers. Veneers are typically made from wood, and they are glued with the grain of adjacent layers perpendicular to each other to improve strength and stability.
Yes, some types of glue can be toxic if ingested, inhaled, or absorbed through the skin. It is important to follow safety instructions when using glue and to keep it out of reach of children and pets.
Acetone, found in nail polish remover, is commonly used to dissolve super glue. Soaking the bonded area in warm, soapy water can also help weaken the bond and make it easier to peel off. Commercial debonders specifically designed for removing super glue are also available.
If superglue sticks everything together why doesnt it stick to th tube?
When inside the tube the solvent can't evaporate, nor can the air get to the chemicals, so until they come out, they wont stick. The proper combination of stretchy and sticky polymers make good glue. ... That's why it doesn't stick to the inside of the bottle.
We know that in, general, metals and superconductors, as well as plasmas and ionic solutions conduct electricity.
Of the metals, silver conducts electricity the best, although it is relatively expensive. Copper is very commonly used because it is the second most conductive metal. We know that Group 1 and Group 2 metals (the alkali and alkaline earth metals) from the periodic table are good conductors. Other metals and metal alloys will also conduct, such as gold, aluminum, tungsten, brass, lead, bronze, iron ferrite, meteorite, tin, steel, iron, titanium, etc. Aluminum is also often used because it is highly conductive, and it much lighter than the other highly conductive metals.
At very low temperatures (meaning the temperature of liquid nitrogen), superconductors are by far the best conductors available. These are far superior to any known metal, but, they do not conduct at anything close to room temperature. Some superconductors have zero resistance, and so there are absolutely no current or power losses as electrons move through the material.
The general idea is that any material with free electronswill be a conductor. The more free electrons, the better the conductor will be. We also know that ionic solutions will conduct electricity. Salt water is an example of this. It should be noted that these materials include those in the solid, liquid and gas phases. As a plasma (an ionized material), electrons are suddenly made available to support conduction because of the fact that electrons have been torn from their orbits to ionize the material in the plasma. There will be a few more minor inclusions, and you can find more information by using the links.
What is the pH of rubber cement?
The pH of rubber cement is typically around 6-7, making it slightly acidic to neutral. However, the pH may vary depending on the specific formulation and additives used in the rubber cement.
Yes, heat can affect glue by speeding up its drying time or weakening its adhesive properties. Excessive heat can cause the glue to dry too quickly or become less effective at bonding materials together. It is important to consider the temperature limitations of the specific glue being used to ensure optimal performance.
How do you get adhesive off of linoleum?
You can typically remove adhesive from linoleum by soaking a cloth in warm, soapy water and placing it over the adhesive to soften it. Once softened, gently scrape the adhesive off using a plastic scraper or putty knife. Avoid using harsh chemicals that may damage the linoleum.
What is the difference of adhesive strength between natural glue and synthetic one?
Natural glue typically has lower adhesive strength compared to synthetic glue. Synthetic glues are engineered to have stronger bonding capabilities and are often more durable and versatile in their applications. However, natural glue may be preferred for certain applications where a more eco-friendly or non-toxic adhesive is desired.
Is glue a homogeneous or heterogeneous mixture?
Glue is a colloid, and colloids and solutions are homogeneous mixtures, therefore glue is a homogeneous mixture.
How do you remove hair glue from clothing?
Most glues that are sold also has a solvent, check where you bought the glue and see if there is a solvent. Also you can try salt, olive oil, shampoo, and club soda mixed on the glue......let it sit for about 10 minutes then rinse out. Do this a couple of times to remove the stain.
"Sticky stuff" typically refers to any substance that adheres to surfaces, making them tacky or adhesive. Examples include glue, tape, sugary residues, or substances like sap or resin.
Gorilla Glue is not toxic once it has dried. However, the adhesive can be harmful if ingested or if the fumes are inhaled during the drying process. It's important to use it in a well-ventilated area and keep it away from children and pets.
Casein glue sets through a process called coagulation, where the proteins in the glue form a gel-like structure as they react with moisture in the air. This coagulation process allows the glue to harden and bind materials together.
What is the mixing ratio for using denatured alcohol to remove water from k-1 kerosene?
I put one third of an 8" soda straw ( used as a dip tube) into 2 quarts of kerosene. be sure to use a clear straw so you can see how much you are putting in,,, you can also use an eye dropper if you want...Good Luck
Does methyl hydrate increase octane in gasoline?
I don't know the exact raise in the octane content. Its been years since I took an organic chemistry class, BUT, i do know that with 2 of my 4 classic cars, using about one to one and a half cups of methyl hydrate to a full tank of gas really helps (also buy premium gas and fill from empty). It is a "petroleum distillate" (which is the same stuff you buy labeled "Octane booster" at like 8 bucks for 7ounces) which means it mixes with the gas well. Also, because of its low point of ignition, it burns, faster, hotter, and cleaner. I also like to use it because it cleans out any gunk in the carburetor while it passes through.
If you have a high performance car, and no that doesn't mean a lowered Honda civic with a cold air intake. You can also use a product called Toluene, much like a paint thinner/ or really strong methyl hydrate, also usually available at hardware stores... is a very good booster. I use it in two of my other classics with 500+hp. Be VERY careful handling Toluene, as well if it drips on the paint surrounding the gas door, it is almost guaranteed to fry though the lacquer in seconds...so use a funnel and pour slowly, and use about the same amount as the methyl hydrate mixture.
Waiver of liability. I, claim no responsibility for any negative incidents that may occur from this information. It is, to the best of my knowledge accurate, and in my instances, works well with my vehicles.
If you mixed cornstarch with glue what would happen?
You would get a sticky mess :P Not so; Actually what you get is something more like Silly Putty, thick or thin depending on how much of each, start with half corn starch and half white glue, adjust to suit your desires. Provides hours of fun, best if you keep it in an air tight container.
Various types of thermoplastics are used in glue guns. The type of thermoplastic depends on the type of gun. Polyoxymethylene, acrylic, polyethylene, ethylenevinyl acetate, and other types of polymers make up the solid glue, when when heated becomes viscous, and re-hardens after cooling.
Deamination is a process in which an amino group is removed from an organic compound, typically an amino acid. This process can occur in the liver during the breakdown of proteins, leading to the formation of ammonia and a keto acid. Ammonia is then converted to urea for excretion in the urine.
