Adhesive manufacturer shares cyanoacrylate adhesive, instant adhesive, fast drying, environmentally friendly and non-toxic
Cyanoacrylate is an acrylic resin with a wide range of applications. When the super glue is applied to the surface of an object, the solvent evaporates, and the moisture on the surface of the object or in the air triggers the anionic polymerization reaction of monomers, forming strong chains that firmly bond the two surfaces together. This polymerization reaction releases heat, so the temperature will slightly increase, and the evaporation of solvents (such as acetone) will bring some pungent odors.
Instant drying glue,
Also known as cyanoacrylate, it can quickly cure on the surface of adhesive materials. The moisture on the surface of the substrate will trigger the curing reaction of the adhesive, spreading from the surface of the substrate to the inside of the adhesive. Instant dry adhesive is widely used in bonding applications that require quick fixation of small components. Due to its limited ability to fill gaps, it is necessary to ensure a tight fit between the bonded surfaces during the bonding process. For most substrates, instant adhesive exhibits excellent adhesion and shear and tensile strength.

Reminder from glue manufacturers:
Long term exposure to air can cause the polymerization of cyanoacrylate, making instant dry adhesive unusable. The opened instant drying glue should be stored in a sealed bottle, and silica gel gel should be placed in the bottle to keep dry.
The advantages of cyanoacrylate adhesives include single component, instant bonding, room temperature hardening, transparent and colorless, high viscosity, etc. However, due to its fast polymerization rate, it has a certain degree of irritation to human tissues, especially as the length of the alkyl group and the number of carbon atoms in the side chain increase, the irritation will decrease. Toxicological evaluation shows that the LD50 of cyanoacrylate in adult acute toxicity tests is greater than 13g/kg, which belongs to the actual non-toxic level and has no carcinogenic or teratogenic effects.
When using instant glue,
The slower curing speed may be caused by low relative humidity in the environment, acidic surface of the adhesive, or excessive bonding gaps. The methods to solve these problems include exposing the parts to the atmosphere for a long time to balance surface humidity, using accelerators to neutralize acidic stabilizers in the glue, providing curing conditions, etc.
Adhesive manufacturers share that cyanoacrylate adhesives have important applications in industrial and medical fields, but attention should be paid to curing conditions and storage methods during use to ensure their effectiveness and safety.
