Cyanoacrylate Adhesive FAQ
Ans. Cyanoacrylates are a family of strong fast-acting adhesives with medical, engineering, and domestic uses. Cyanoacrylate adhesives have a short shelf life if not used, about one year from manufacture if unopened, about one month once opened. Shelf Life of glue may variate depending upon some conditions relating to quantity, quality, curing time and storage temperature. They have some minor toxicity.
Ans. Super Glue was invented accidently while working in laboratory. It is, also known as cyanoacrylate, was initially exposed in 1942 by Dr. Harry Coover, who by the way died last month on March 26th, 2011. Coover was attempted to make clear plastic gun sight to be put on guns used by Allied soldiers in WWII.
Ans. Acetone dissolve Glue bond. Acetone is sold at the hardware or chemist stores. In case of availability you may also try nail polish remover which also have acetone in their composition.
Ans. Do not attempt to tear or force apart the glue. This could rip your skin. Apply acetone-based nail-polish remover to the part. The acetone breaks down the glue bond.
If there's a lot of glue on your top, steep the skin in nail-polish remover to melt the bond. Clean the area with soap and water after removing the glue. If you don't have nail-polish remover,steep the affect skin in warm and soapy water. Slowly roll the skin to work the bond apart as the hot water soak through. Continue doing this pending the skin is free of glue.Ans. When CAs cure they volatize, creating the appearance of a white haze around the bond line. This phenomenon occurs when the cyanoacrylate monomer react with moisture in the air, and settles on the part. On areas where this may be a problem, our company have special grades for this type of application. This grade is also known and non-blooming grade.
Ans. Most surfaces are not smooth. Glues fill the gaps, building a bridge between the 2 surfaces and after thatharden due to the moisture in the air keeping the bond together. If the surface is plane and smooth then Low viscosity grade can work well. But on rough surface high viscosity glue or gel may be applied to fill the gaps.
Ans. In general 1 drop is enough for 1square inch joint. Less glue is enough - excessive glue can makes a bond weaker.
Ans. Bottle is itself designed as a Universal applicator. Extra-long nozzle may be supplied on request if needed for pin point precision applications on hard to reach places and small spaces.
Ans. cyanoacrylate adhesives are not poisonous. The fumes from cyanoacrylate adhesivegets vaporize and do bother sensitive membranes like eyes, nose and gullet. When these vapors come in contact immediately polymerize when comes in contact with clammy surfaces. They do not effect and penetrate into human skin tissue. There are many applications where specially formulated medical grades of cyanoacrylates have been used to graft skin, bond bone and cartilage, renovate eye hankie, close blood vessel and stop spinal liquidleak.
Ans. Cyanoacrylates are best to store in their original container in a cold temperature below 20 degree Celsius, in dark, and dry location. The shelf life of general purpose cyanoacrylates stored at room temperatures can be up to six months to one year depending upon offered grade.
Ans. We are specialized and offer tailor made solutions to our clients and develop grades as per special needs of our users. There is no "one" perfect adhesive that works best on all materials cyanoacrylates are used for the following reasons: quick cure, single component, high tensile/shear strength, able to bond similar and dissimilar materials, easy to mete out, low for each unit cost, and a variety of other factors. There may be different type of grades which may variate in terms of viscosity, shelf life, curing speed, blooming or non-blooming in different range of packaging.
Ans. The biggest reason is less overheads and bulk production. We always kept our overhead very low in order to offer lower cost cyanoacrylates to the Industrial Market. Being in the cyanoacrylate business for many years we offer best quality industrial cyanoacrylates to all industrial customers at the lowest prices.
There are perhaps thousands of applications where cyanoacrylates are used to save developed time and money. Here is a small list: flex pasting or sign board making, footwear manufacturing, helmet, Automotive trim, ganging batteries, bow/arrow vanes, cell phone covers, printed circuit board application, beauty cases, dental application, throwaway medical products, fishing lures, furniture and other repair, guitars, hearing aids, honing stones, jewellery, lamp shades, finger print identification, loud speakers, luggage, mortuary applications, oil filter, o-rings, RC plane/cars, rubber mats, security packaging, shoe repair, silk screens, steering wheels, toys, transformers, weather stripping, etc..
Ans. CA glue, instant glue, cyanoacrylate, and super glue are different names for cyanoacrylate adhesive. Even though these all explain the same type of glue, changed groups of users use.
Ans. Cyanoacrylate adhesive can bond almost everything but there are some tough application like bond on HDPE, LDPE, PP, Teflon, foam, mirrors and greasy surfaces is not possible, but in some cases it may acquaintance by applying particular grades. There is bond failure in parts that have regular vibrations.
Ans. The shelf life of cyanoacrylate adhesives is limited up to few months depending ahead grades, bunch size, and class and curing speed. So after expiry it is definitely going to be dried.
Ans. POLYFIX® Instant glue will form a tough bond in about 30 to 60 seconds so you can usually just hold pieces in place until the bond sets in few minutes.
Ans. POLYFIX® INSTANTGLUE in the tip of the nozzle is reacting with moisture in the small orifice gets hardens. Normally once the instant POLYFIX® CA harden the consumer will take a pin and join it down into the needle to open it up only to find it block up even earlier the next time. What happens is the pin scratch the inside of the needle, which allows even more POLYFIX® CA to stay in the needle cause it to block up faster. This method will be frequent sometimes until the nozzle is no longer able to be used and gets thrown away.
Ans: When using CA to bond glass, the power is firstly strong but degrades radically over time. The cure speed is particularly fast due to the basic nature of glass which likely generates high stress in the bond line instantly adjacent to the glass at a molecular level. This high stress makes the cured polymer around the bondline susceptible to chemical and physical degradation as a response overtime to tightening and growth of the joint with changes in temperature, or hydrolytic attack by moisture, etc. A permanent bonding in joints cannot be achieve when bond substrates involving glass.
Ans: cyanoacrylates adhesives are acid stabilized, single component adhesives that react quickly at room temperature when contacted with moisture (a weak base) or dust particles between tight bond lines.
