How to do the instant adhesive not white, what to do if the glue dries too fast

Why does instant adhesive turn white?

Instant glue, the main components are cyanoacrylate, acid stabilizer and thickener. When the cyanoacrylate molecule partially volatilizes and reacts with the moisture in the surrounding environment and falls, the white powdery residue left behind is bleaching or frosting.

The specific reasons for the whitish instant adhesive are as follows:

1. Too much glue is used for instant adhesive, which can easily lead to whitening.

2. The use environment is not well ventilated, and the quick-drying glue relies on the moisture on the surface of the substrate to solidify, which is easy to form whitening.

3. Before using instant adhesive, the surface of the bonding substrate is not treated, and there is moisture or dust.

4. One of the most common reasons: sweaty hands of operators.

5. The curing time of cyanoacrylate is different for different adhesive surfaces, the cyanoacrylate is not completely cured, and it is anxious to enter the next process, and the glue is still in the reaction, and it is easy to whiten.

How to avoid instant adhesive whitish?

1. Control the amount of glue according to the different adhesive surfaces, and use the coating device if possible to effectively manage the amount of adhesive so that it will not overflow, so as to prevent whitening.

2. Ensure sufficient air flow in the assembly area, which can assist the fan and reduce whitening.

3. Do a good job in the surface treatment of the bonding substrate, and you can use accelerators to accelerate curing. The rate of hardening is faster, which avoids reacting with moisture in the air and thus whitening.

4. Using KY low whitening instant adhesive, this type of instantaneous adhesive, the monomer is not easy to evaporate, so it is not easy to cause whitening.

how to achieve no bleaching of quick-drying glue;

1.The amount of glue must be well controlled, and it is easy to whiten if the amount of glue is too much.

2.Pay attention to ventilation, the air in the working environment is relatively sealed, because the instant adhesive is cured by moisture. In the process of curing the glue, the white mist left behind is easy to form whitening.

3.After the product is dispensed, it can not be sealed immediately, it is best to place it for 24 hours in a sealed package, of course, the first should be the choice of non-whitish instant adhesive such as CA-60H glue.

It is entirely possible to control the working conditions without whitting or with very low bleaching.

White latex can dry fast processing method:1. Use the cold air and electric fan to increase the circulation of air.

2. Enlarge the place with high temperature, such as drying under the sun.

3. Put it in a dry place, it will be cured soon, and if possible, it can be blown by the appropriate amount of wind.

4. Keep the air, do not press, the white latex needs to be exposed to air and volatile moisture to be completely cured, and the white latex can not be properly exposed to the air and the moisture cannot be volatilized, so the curing time will be extended.

5. Choose the right items to use to accelerate the curing time, white latex is mainly used for the bonding of wood, the rougher the wood curing time, the faster the viscosity. Because the rough wood makes the white latex contact with air larger, the moisture can be completely volatilized, and the rough wood also makes the white latex have more gripping points, so the viscosity will be stronger.

1. Reduce the ambient humidity and the moisture content of the sticky material, etc., which can strengthen ventilation and pressurization to improve the "drainage capacity" of the sticky material.

2. Volatile substances (such as ethanol, etc.) can also be added to white latex to "take away water".

The drying principle of white latex: the drying process of white latex is the process of evaporation of water in white latex into the air, or absorption and evaporation by porous adhesive materials

After the construction of white latex, according to its own performance and natural environment, it can be quickly dried, dry conditions, high temperature and good ventilation area, I hope to help you.

The reasons for the whitishing of instant adhesive are: 1. The air humidity is too high, about 60% is the most suitable, 2. There is water vapor and sweat on the adhesive surface. 3. No ventilation within 24 hours after gluing.

It is recommended to wear disposable PE gloves to operate, keep the adhesive surface clean and dry, put the product in a ventilated environment after gluing, and then pack it after 24 hours, or directly use it with HY-252 treatment agent. You can also directly use HY-306 non-whitish instant adhesive or other slow-drying glue, and there will be no whitening phenomenon.

Summary. Hello dear <>

The glue dries too quickly, and the ambient temperature and humidity have an impact on the drying speed of the glue. Lower temperature and humidity will slow down the drying rate of the glue, while higher temperature and humidity will accelerate the drying rate of the glue. According to the instructions for the use of glue, the temperature and humidity of the use environment can be controlled.

Adjust the thickness of the glue: The thickness of the glue will also affect the drying speed. Generally speaking, the thinner the thickness of the glue, the faster the drying speed; The thicker the glue is applied, the slower the drying rate.

According to the requirements of the glue and the actual situation, the thickness of the glue can be adjusted to control the drying speed of the glue.

The thickness of the glue can be adjusted according to the requirements of the glue hole and the actual situation to control the drying speed of the glue.

The glue is made of some chemicals with adhesive effect mixed with slow brightness and auxiliary materials, commonly used is polyvinyl alcohol, starch, etc., the general adhesive principle of glue is that the adhesive molecule penetrates into the gap of the object to be bonded, and the molecule of the item that needs to be bonded produces a wide attraction, so as to produce a viscous sensitive high effect. Have a great day, dear ones. Hope mine is helpful to you!

If the glue dries too quickly, it may result in an unsatisfactory bonding or the inability to make the necessary adjustments and corrections. Here are some things you can try to slow down the drying of glue:1

Adjust the ambient temperature and humidity: The drying speed of the glue is affected by the ambient temperature and humidity. If the ambient temperature is too high or the humidity is too low, you can adjust the environmental conditions by adjusting the air conditioner or humidifier to slow down the drying rate of the glue.

2.Replace the glue used: Different types of glue dry at different speeds, so you can try to replace the glue that dries slower.

3.Add thinner: Some glues can use thinner to adjust their viscosity and drying speed.

A suitable diluent can be added in the right amount to slow down the drying speed of the glue. 4.Change the coating method:

The coating thickness and method also affect the drying rate of the glue. Try applying the glue thinly and using a tool such as a brush or sponge beam to slow down drying. It should be noted that the above methods may affect the adhesive effect and strength of the glue, and should be carefully adjusted according to the specific situation.

When using glue, you should read the instructions for use of the glue carefully and follow the instructions to ensure that the glue can exert the best bonding effect.
