Anonymous users2024-02-11It's the recipe of the glue you use and the materials you use. In the process of chemical reaction and solidification of A glue and B glue, the colloid will volatilize a gas, which is the solvent in the glue according to our engineering. This is something that can be improved by glue manufacturers.
If you have any questions, you can continue to ask me, I am also an AB glue manufacturer.

Anonymous users2024-02-08Is it the formula produced by AB glue that contains volatile solvents. General AB glue has no taste after curing.

Anonymous users2024-02-061.The glue does not cure:
Possible causes: too little or too much curing agent; The glue is stored for a long time, and it is not stirred or evenly before use;
2.The glue that was supposed to be hard glue is soft after curing:
Possible causes: Incorrect glue ratio: such as not proportioning according to weight ratio or large deviation;
3.Some places the glue cures, some places the glue does not cure or does not cure completely:
Possible causes: uneven stirring;
4.After curing, the surface of the glue is very uneven or there are many bubbles:
Possible causes: curing too fast, heating and curing temperature too high, close to or beyond the operation time potting and dispensing;
5.After curing, the surface of the glue is oily
Possible causes: Water and humidity during the glue filling process.

Anonymous users2024-02-05This may be due to uneven mixing or incorrect proportions, you can go to Xinwei for consultation.

Anonymous users2024-02-04Most of this is acrylic AB glue, which has the characteristics of high bonding strength and fast curing speed, but the general ones have color, poor transparency and big odor. If it is packaged after curing, it is difficult to disperse the smell, so it is recommended to place it in a place with a good energy environment for one to two days before packaging.

AB glue needs to be stirred evenly.

Anonymous users2024-02-02I have encountered this phenomenon you mentioned before, and the smell is pungent, it should be a problem with the quality of AB glue, you can change to another manufacturer's AB glue!

Anonymous users2024-01-30Epoxy resin encapsulant is generally sold in many places.
If it's a specific model, you just need to find their dealer.
Commonly used epoxy resin encapsulant brands are Hasuncast, Huitian, Kasute and so on.
When choosing an epoxy adhesive, a number of factors should be considered. Here are some small experiences that I hope will help you. As a high-performance, high-value-added adhesive, epoxy resin adhesive is highly valued by the industry, but at the same time, counterfeit and shoddy products are often patronized. >>>More
At present, there are three main types of potting compounds on the market: epoxy system, silicone system, and polyurethane system. >>>More
Why don't silicone encapsulants cure?
1. The electronic scale is not accurate enough, resulting in the incorrect content of AB agent. When there is too much agent A and less content of agent B, it cannot be cured normally. >>>More
At present, the glues for pavement treatment include pavement hot-melt joint filling glue, epoxy resin cold repair glue, and joint filling asphalt. >>>More
Many people don't understand silicone, so they say that the whole compartment is a defective product, in fact, because the PC lens and the silicone itself have no adhesion, so the compartment is normal, and there are two ways to do it without a compartment on the market, 1 is to fill with jelly glue, because the jelly glue has a certain adsorption and can be adsorbed together with the lens, so the compartment can not be seen at that time, but there will be a local compartment after a long time, and the jelly glue itself has no hardness too soft, and the expansion coefficient is large. Therefore, in some hot and cold environments, there will be bubbles in the packaging process from the injection hole (such as the early Dow Corning's OE6450 is a good example), this packaging process is derived from the previous optocoupler packaging, but not suitable for imitation lumen filling process, 2 use the primer (lens cleaning agent) of the electronics industry as the third medium to bond the PC lens and silica gel together, but the primer in the electronics industry can not be used for optics because it is not resistant to high positions, and has a great impact on light decay, and this primer is also used in LED packaging abroad. But not in the illuminated area only for the bottom of the bracket. Therefore, it is recommended to use a fully spaced package to ensure stability and quality.
