Recently, due to weather changes, UV glue problems are more frequent, now Libang to give you one by one answer.                                1. How to remove the overflow? Soft cloth and paper towel can be used to wipe the overflow glue gently, which can be dipped in acetone alcohol. It is easy to remove after positioning, and it needs to be scraped off with a knife after completely curing. 2. Why is the surface of glue sticking and not dry when it overflows or is fixed? Surface dryness is the weakness of UV curable adhesives, which is caused by oxygen polymerization. High power light source can be used for fast curing, or curing under nitrogen protection. 3. Why do you feel that the bonding strength of some adhesives decreases in winter? When the temperature of UV glue drops in winter, the film will become hard and brittle, resulting in the decrease of sensory strength. It is necessary to adjust the adhesive formula in low temperature area in winter to make it have better low temperature toughness. 4. How long does it take for UV adhesive to cure completely? According to the specific UV adhesive and the curing lamp used by customers, it can not be generalized and needs to be determined by experiments. If the intensity of UV light is high and the irradiation time is short, it can be cured, and vice versa. 5. How to separate or remove objects bonded with UV glue? When the bonding is not good, it is necessary to separate or remove the adherent for re bonding. According to the specific adhesive and adherent, the methods can be used include electric hair dryer heating, boiling, steam fumigation, acetone or ethanol immersion, or long-time water immersion. Libang is an excellent R & D and manufacturer of electronic adhesives, mainly engaged in: UV adhesive, LED lens adhesive, thermal conductive adhesive, phase change thermal conductive paste, thermal conductive silicone sheet, thermal conductive silicone grease, silicone sealant, etc. Strive for perfection and make the world!3 ]# G) S+ M- y& L# n。。。。。
