Introduction:
406 adhesive is a one-component, low-viscosity cyanoacrylate adhesive.
The characteristics of 406 glue are as follows:
First, the characteristics:
Low viscosity, universal type and good permeability. It has the function of rapid curing. It is especially suitable for bonding difficult bonding materials. Typical uses: quick bonding: self-bonding and quick bonding of most metal, plastic or elastomer materials. It is used for bonding porous, acidic and absorbent materials, especially for bonding plastics or rubber (EPDM) that need to be fixed quickly.
Second, the characteristics:
In general, the moisture on the surface of the material will cause the curing of 406 glue.
Although 406 glue can reach full practical strength in a relatively short time, it must be cured at least 24? Hours, with complete chemical resistance/solvent resistance.
Third, speed:
(1) Relationship between curing speed and bonding material Curing speed depends on the bonded substrate, and the relationship between curing speed and bonding gap Curing speed depends on bonding gap. The smaller the bonding gap, the faster the curing speed. The larger the bonding gap, the slower the curing speed.
(2) Relationship between curing speed and accelerator When curing is too slow due to excessive bonding gap or low humidity, accelerator can be used to improve curing speed. However, this treatment will reduce the final strength of the adhesive layer. Therefore, it is suggested to carry out experiments to determine the actual effect. Others point out that Le Tai 406 glue is not suitable for pure oxygen and/or oxygen-enriched environment.
Four. Toxicity:
Glue containing volatile organic compounds (VOC) is toxic when it volatilizes. The main sources of VOC are paint and glue, and the harm to human body is mainly eyes, skin, respiratory system and blood circulation system. After curing, most of the glue is nontoxic.
Verb (abbreviation for verb) uses:
If this product comes into contact with trace water vapor in the air, it will be rapidly polymerized and solidified by catalysis, so it is called dry glue. This product is widely used for bonding flexible materials, rubber products, soft and hard plastics, etc. Whether individually or mutually. However, for materials that are difficult to stick, such as polypropylene, polyethylene and TPU, the surface needs special treatment before sticking.
Well, after reading the properties of 406 glue, I think everyone has a new understanding of 406 glue! There are many glues of various brands and sizes on the market, but many friends don't know which one is better. In most cases, they still rely on the recommendation of the clerk, but they must know enough to buy the right product. Therefore, it is necessary to know something about glue. After that, the final decision was made through the performance of glue and the comparative analysis of various brands.
