The electrical manufacturing industry is familiar with electronic sealants, which have many excellent properties when cured, but need to be constructed correctly and cured correctly. If the construction is not correct, the curing environment is not good, or the substrate is moved during the curing process, all kinds of accidents can occur.
What does an electronic sealant look like after normal curing?
After normal curing, the electronic sealant shows a glossy film, which is elastic to the touch, soft and hard, with a high tensile rate and not easy to break. It is not easy to fall off in the bonding parts, waterproof, moisture-proof, temperature-resistant, sealing performance is good.
What does the electronic sealant look like after it has been cured abnormally?
There are many reasons for the electronic sealant to be cured under abnormal conditions, the curing of the adhesive body wrinkles, peeling, easy to break are common consequences. When used in the bonding of electrical enclosures, the waterproof performance is poor and water penetration is easy, reducing the quality of the appliance. If you want to improve the quality of electrical appliances, besides, to control the quality of the glue, but also need to pay attention to the curing process, not sloppy, standard construction is very important.
At the same time, electronic sealant in the abnormal curing, the quality of the glue to be examined, need to test whether the environmental requirements. Even good quality electronic sealants need to be standardized, such as Cosmo, which focuses on the research of sealants and provides customized solutions for sealant applications, because the glue contains ethanol, and if it is not cured through the normal process, the ethanol in the glue cannot be completely evaporated.
How long does it take for an electronic sealant to cure?
The curing process of electronic sealants starts from the surface and cures inwards. The surface only takes 3 to 15 minutes to crust, and it takes 24 hours to cure completely. 7 days of curing is required for the performance to be more stable and the tensile rate to be tested to the expected level and the tensile strength and bond strength of the adhesive to be guaranteed.
The electronic sealant bonding material is very wide, the bonding talent requirements are relatively high, no matter which bonding adhesive material, need to protect the surface clean, no oil, no water, no dust, otherwise the bonding strength is reduced, the use of the process is easy to de-glue.
