Why does the Cyanoacrylate adhesive whitening ?
Why does the Cyanoacrylate adhesive whitening ? We should all have some doubts, quick dry glue application in life is a lot of, the most common is 502 glue, basic any material can be glued, and is very fast, but after the completion of the bonding will always appear white phenomenon, it is a headache, so what is the reason for quick dry glue white?In front of small make up has said many times.
First of all, the application field of Cyanoacrylate adhesive is well known, metal silicone, plastic, hardware, weaving and so on are effective bonding success, but excellent bonding characteristics but a fly in the ointment: it is easy to white.The effect on bonding parts is also obvious, especially for products with colors other than white.
Why fast dry glue volatile white
The phenomenon of whitening is actually related to the type of quick-drying glue itself, in which the main substance of solvent, alpha-cyanoacrylate resin, and the reactivity of water in the air affect whether it will whiten or not.
1, quick dry glue use too much glue, easy to lead to white phenomenon (quick dry glue coating amount is not the more, the better, glue coating should be appropriate, as far as possible, the thinner the rubber layer, the higher the strength).
2. Due to insufficient ventilation in the sizing site, the instant glue can be cured by moisture on the surface of the substrate;
3. Before using the adhesive, no cleaning treatment has been done on the surface of the base material to be adhered. Moisture or stains may directly cause the phenomenon of whitening.
At present, it is difficult to solve the problem of quick dry glue without white in the market. There is no such situation that the adhesive parts cannot be white at all. At present, we can only try our best to reduce the phenomenon of white.
There are many types of quick-drying adhesives in our company, and there are 460, 490, 601, 603 adhesives that can be used to cooperate with various bonding processes. According to the white-out phenomenon, our engineers provide a solution: we can cooperate with ts-1 to help reduce the white-out of quick-drying adhesives.In some processes, k770-2 low-whitening silica gel primer can also be used together with instant adhesive.
