All of us know what super glue is. It is a handy item around the house, lest you have accidentally broken ceramic pieces that need repairing. However, be careful it is not food safe. You should not touch your mouth while working with it.

Super glues are quick setting agents used for joining broken pieces of decorative or antics of ceramic, metal, plastic, leather, vinyl rubber, and similar surfaces. An undesired fall of your favorite vase may result in a crack or three broken pieces. With the tip of the glue tube, the super glue can bind the pieces together looking like a perfect piece.

What is Super Glue?

Super glue is a synthetic adhesive that binds together broken household items. As the major ingredient of super glue is Cyanoacrylate, it is not food safe. Cyanoacrylate is a cyanide derivative, which is a toxic chemical that is not FDA-approved to come into contact directly or indirectly with food.

Superglue was an unintentional creation by Dr. Harry Coover in 1942. The world realized the potential of super glue as an adhesive in 1958 when it went to the market for sale by the name of Loctite. Ever since the superglue is popular as an adhesive for home items.

Super glue comprises a binding agent, a major chemical called cyanoacrylate. The unique property of the glue shows the formation of unbreakable bondage. Only 9 drops of superglue could lift a car weighing 5 tons. The adhesive capacity of the superglue is incredible!

Loctite glue in the liquid form is available in a 20g bottle. You need only a few drops of glue at a time. After the application of the superglue, you need to leave it for only 10 minutes for it to dry. Complete curing of the glue will take 24 hours.

Is Super Glue Safe?

Super glue, also known as cyanoacrylate adhesive, is generally considered safe when used as directed. It is commonly used for bonding materials such as plastic, metal, rubber, and ceramics. However, like any adhesive or chemical product, it is important to take appropriate precautions and use it responsibly.

Here are some safety tips when using superglue:

• Read and follow the instructions: Always read and follow the instructions provided by the manufacturer. Different brands of super glue may have slightly different usage guidelines.
• Use in well-ventilated areas: Super glue can release fumes that may be irritating to the eyes and respiratory system. It is advisable to use it in a well-ventilated area or consider wearing a mask if you are sensitive to fumes.
• Avoid contact with skin and eyes: Super glue bonds quickly and can stick to skin, causing irritation or even minor burns. If you accidentally get super glue on your skin, do not pull or force it off. Instead, soak the affected area in warm, soapy water or use an acetone-based nail polish remover to gently dissolve the glue. If glue gets into your eyes, seek medical attention immediately.
• Keep out of reach of children: Super glue should be stored in a safe place, out of the reach of children. Accidental ingestion of super glue can cause health issues and may require medical attention.
• Use in the intended manner: Super glue is designed for bonding materials together, and it is not meant to be used as a substitute for other products or for medical purposes. Avoid using it on or near open wounds, and do not use it as an adhesive for dentures or other medical devices.

Overall, if used properly and with caution, super glue is considered safe for most household applications. However, it is always wise to follow the instructions and take necessary safety precautions to minimize any potential risks.

How Does the Super Glue Work?

The chemical cyanoacrylate has bonding characteristics because of the acrylic monomer that undergoes anionic polymerization with the moisture content of the surface material. As it requires a water molecule for bonding, it can glue onto any surface in the presence of air.

 

As the glue dries up quickly, it is better to work with the glue with comfort and steadiness. There are however different kinds of glues for different surfaces.

How to Use Super Glue Safely?

Because of the cyanoacrylate content of superglue, it needs special care while working with it. If you drop superglue in your finger and put the fingers, the fingers will glue together and you will lose the skin and muscle to separate them. The advice is to put on hand gloves while working on repairing broken materials.

The common practice is to clean the surface of dirt and oil before you apply super glue. The contaminants negatively affect the bonding and time of drying of the glue.

If you are working with a big surface of leather or wood that will have a long exposure, the practice is to use a hood and cover the surrounding surface. The fumes of the cyanoacrylate in the vaporized form cause irritation to the respiratory system such as the nose, eyes, throat, and lungs. Wearing a protective hood while working for a long time will prevent hurting those delicate membranes.

The shelf life of superglue is only a year from manufacture and lasts a month, once opened. Storing in a cool place or a refrigerator will elongate the shelf life. The opening of the tube must be clean with no air the lid should be tight before storing.

How to Work with Super Glue and Metal?

Superglue works very well in gluing metals with metals. The Loctite glue is especially good for creating strong bondage in metals. It is also ideal for porous and not-so-porous materials.
