how does cyanoacrylate adhesive cure ?
traditional cyanoacrylate adhesive (ca) is an acid-stable, single-component adhesive that quickly reacts and cure at room temperature when it comes into contact with moisture (weak alkali) between close materials.
mxbon, our innovative uv-curing cyanoacrylate adhesive (uvca), possesses the same curing mechanism as traditional ca but also includes a photoinitiator.
it rapidly polymerizes and solidifies when exposed to light of the correct wavelength (long-wave uv light and visible light).
what is the blooming phenomenon in cyanoacrylate adhesive ? how can it be improved ?
the monomers of uncured ca can escape and react with the moisture in the surrounding environment, then fall back onto the bonded surface, leaving a white frost-like residue. this phenomenon is known as blooming.
there are several ways to prevent or improve the blooming phenomenon before the ca cures: reduce the amount of adhesive, prevent spillage, and accelerate curing (accelerators or baking).
after the ca cures: avoid sealed spaces, ensure ventilation, and exhaust air. however, the simplest and quickest solution is to use our mxbon #22 series of ca, which offer extremely low odor and minimal blooming.
what is stress cracking in plastics ? what causes it ?
uncured liquid adhesives that remain on certain plastics (like pc, abs, pmma, etc.) under stress conditions may cause cracks to form on the plastic materials.
some practices can help avoid or reduce stress cracking, such as quickly assembling after applying glue, using reinforced plastic materials, and applying accelerators to speed up curing.
we would recommend using our mxbon uv-curing cyanoacrylate adhesive (light cure ca) products.
why is cyanoacrylate adhesive not recommended for glass ?
when cyanoacrylate adhesive (ca) is used to bond to glass, its strength is initially high but can decline dramatically over time.
due to the basic properties of glass, the curing speed is very fast, which can generate high stress in the adhesive layer parallel to the adjacent glass.
this high stress makes the cured polymer around the glue layer prone to chemical and physical degradation, responding to the shrinkage and expansion of the adhering surface due to changes in temperature or the hydrolysis action of water.
therefore, it will not achieve permanent adhesion when bonding to glass.
how to store cyanoacrylate adhesive?
mxbon cyanoacrylate adhesive (ca) is an industrial-grade product that also belongs to the moisture-curing type of products.
for optimal properties and quality, it is recommended to store unopened bottles of ca in a refrigerator at low temperatures.
once the bottle of ca is opened and not completely used, it's best to store the bottle at room temperature, as placing it back in the refrigerator could lead to condensation of moisture contaminants and cause the ca to react and cure.
however, we still recommend using it up as soon as possible.
