It is important that you realize not all adhesives work well with vol- ume lashing. You want to have more FLEXIBLE properties in the glue for volume lashing, rather than speed properties. It is impor- tant that the adhesive dries quickly, but it is imperative that it have flexible properties to sustain longer amounts of time in be- tween fills. When using glue during volume, it is important that you know that less is more. Just because you are putting more exten- sions on a natural lash, does not mean you use more glue. The less glue you use, the cleaner your work will be, and less stickies. Too much glue can weigh down your natural lash and cause "sticks" when doing volume lashing. It is important to lower your lashes into the adhesive slowly with just literally like 2 - 3mm of ad- hesive that's all and as you are coming up out of the adhesive the slower the better to make sure there is no excess adhesive so you don't have to swipe or wipe any excess off.

My one important tip is to ensure a 100% solid bond is

NEVER wipe or swipe your adhesive EVER!!
When you wipe off excess adhesive while lashing it actually creates more air exposure. Since adhesives dry so quick what you wind up doing is actually start the drying process so by the time you place your lashes down onto the natural lash for placement the bond is not going to be so great. If you see lashes lifting up off the base of your connection when you are doing lash fills, this is usually caused from swip- ing the lash while placing or wiping off excess adhesive be- fore placing your lash connection. This goes for classic or volume or any kind of lash extension technique!

Cyanoacrylate is the generic name for a family of fast-acting adhesives with industrial, medical and household

uses. They include methyl 2-cyanoacrylate, ethyl-2-cyanoacrylate (commonly sold under trade names like "Super Glue" and "Krazy Glue"), and n-butyl cyanoacrylate (used in veterinary and skin glues). The related compound 2-octyl cyanoacrylate is a medical grade glue; it was developed to be non-toxic and less irritat- ing to skin tissue. Cyanoacrylate adhesives are sometimes known as instant glues. The abbreviation "CA" is com- monly used for industrial grades.

More recently, formulations are available with additives to increase shear strength, creating a more impact resis- tant bond. Such additives may include rubber, as in Loctite's Ultra Gel, and/or unspecified additives, as in Instant Krazy Glue's ADVANCED Formula. Phthalate-based plasticizers are used in situations where good resistance to water and oils is required.

In general, cyanoacrylate is an acrylic resin that rapidly polymerises in the presence of water(specifi- cally hydroxide ions), forming long, strong chains, joining the bonded surfaces together. Because the presence of moisture causes the glue to set, exposure to moisture in the air can cause a tube or bottle of glue to become unusable over time. To prevent an opened container of glue from setting before use, it must be stored in an airtight jar or bottle with a package of silica gel. Another tactic is attaching a hypodermic needle on the opening of glue. After applying, residual glue soon clogs the needle, keeping moisture out. The clog is removed by heating the needle (e.g., by a lighter) before use.

The fumes from CA are a vaporized form of the cyanoacrylate monomer that irritate sensitive membranes in the eyes, nose, and throat. They are immediately polymerized by the moisture in the membranes and become inert. These risks can be minimized by using CA in well ventilated areas. About 5% of the population can become sensitized to CA fumes after repeated exposure, resulting in flu-like symptoms.[16] It may also act as a skin irritant and may cause an allergic skin reaction. The ACGIH assign a Threshold Limit Valueexposure limit of 200 parts per billion. On rare occasions, inhalation may trigger asthma. There is no singular measurement of toxicity for all cyanoacrylate adhesives as there is a wide variety of adhesives that contain various cyanoacrylate formula- tions.

The United States National Toxicology Program and the United Kingdom Health and Safety Executive have concluded that the use of ethyl cyanoacrylate is safe and that additional study is unnecessary.[17] 2-octyl cyanoacrylate degrades much more slowly due to its longer organic backbone that slows the degradation of the adhesive enough to remain below the threshold of tissue toxicity. Due to the toxicity issues of ethyl cyano- acrylate, the use of 2-octyl cyanoacrylate for sutures is preferred.

Reaction with cotton

Applying cyanoacrylate to some materials made of cotton or wool (such as cotton swabs, cotton balls, and certain yarns or fabrics) results in a powerful, rapid exothermic reaction. The heat released may cause serious burns,[18] ignite the cotton product, or release irritating white smoke. Material Safe- ty Data Sheets for cyanoacrylate instruct users not to wear cotton or wool clothing, especially cotton gloves, when applying or handling cyanoacrylates. OFF-THE-SHELF NON- MEDICAL-GRADE GLUES ARE UNSUITABLE FOR MEDICAL APPLICATIONS, AS THEY MAY CONTAIN SOLVENTS (E.G. METHYL ALCOHOL) AND PRODUCE HEAT DURING POLYMERIZATION.

Solvents and debonders
Acetone, commonly found in nail polish remover, is a widely available solvent capable of softening cured cyanoacrylate. Commercial debonders are also available 

Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-2-propenoic acid. It is a colorless liquid with low viscosity. It is the main component of cyanoacrylate glues and can be encoun- tered under many trade names. Super glue and Krazy glue are believed to be ECA.. ECA polymerizes rapidly in presence of moisture.

Ethyl cyanoacrylate is prepared by the condensation of formaldehyde with ethyl cyanoacetate:
Ethyl cyanoacrylate is used for gluing of various materials. It finds applications also in medicine, for liquid ban- dages.

Methyl cyanoacrylate (MCA) is an organic compound that contains several functional groups, a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyano- acrylate glues.[1] It can be encountered under many trade names. Methyl cyanoacrylate is less commonly en- countered than ethyl cyanoacrylate.

IIsobutyl cyanoacrylate is an isomer of butyl cyanoacrylate. It is used in medical procedures either to close inci- sions and lacerations without the use of sutures, or as an adjunct to strengthen the suturing. This use is possible because it is a bactericidal liquidmonomer which, in the presence of small amounts of moisture, rapidly polymer- izes to form a strong adhesive.

n-Butyl cyanoacrylate (n-BCA, NBCA), a cyanoacrylate ester, is a butyl ester of 2-cyano-2-propenoic acid. It is a clear colorless liquid with a sharp, irritating odor. It is insoluble in water. Its chief use is as the main component of medical cyanoacrylate glues
They arebacteriostatic and their use is usually painless

Butyl esters provide stronger bond, but are rigid. Octyl esters, while providing weaker bond, are more flexible.

Octyl cyanoacrylate (OCA), a cyanoacrylate ester, is an octyl ester of 2-cyano-2-propenoic acid. It is a clear colorless liquid with a sharp, irritating odor. Its chief use is as the main component of medical cyanoacrylate glues. It can be encountered under various trade names including GluStitch, derma+flex QS, SurgiSeal, FloraSeal,, Der- mabond, and others.

In medical and veterinary applications, octyl cyanoacrylate, n-butyl cyanoacrylate and isobutyl
cyanoacrylate are commonly used. They provide rapid wound closure, are bacteriostatic, and their use is usually painless. Butyl esters provide a stronger bond, but the glue is rigid. The octyl ester, while providing weaker bond, is more flexible.

Heating to higher temperatures causes pyrolysis and depolymerization of the cured glue, producing gaseous products strongly irritating to lungs and eyes.

Besides Humidity & Temperature reacting with CA, Chemicals can have an impact on adhesives as well. Such as ammonia in hair color, if you work in a hair salon and they do a lot of chemical services you may notice your adhesive dries up super quick and you may not even realize why it is happening. Chances are it's the ammonia in the air that is causing this.
