Generally, the normal storage of epoxy AB adhesive is stored at room temperature, and the curing after mixing is greatly affected by temperature, the higher the temperature, the faster the curing speed, and the slower the temperature is, the phenomenon of bursting will occur if the temperature is too high
How many degrees of high temperature can epoxy AB glue withstand?
Epoxy resin AB adhesive is a fast curing series, transparent viscous epoxy resin adhesive; Can be cured at low temperature or room temperature, curing speed is fast; High bonding strength, good hardness and toughness after curing; After curing, it has good acid and alkali resistance, good moisture, water, oil and dust resistance, and resistance to humidity and heat and atmospheric aging. After curing, it has good electrical and physical characteristics of insulation, compression resistance and high bonding strength. So how many degrees of high temperature can epoxy AB glue withstand? Its operating temperature is -50 ~ +180℃, and can reach +250℃ for a short time. For different product processes, the temperature is also different, 100 degrees, 200 degrees, 300 degrees, 1000 degrees and so on.
ab glue maximum temperature resistance how many degrees?
AB glue can be divided into the following categories.
1. Acrylic AB adhesive: The main material is acrylic ester. Room temperature curing, high mechanical strength, toughness. A wide range of materials can be bonded. Mainly used in all kinds of result bonding. For example, the bonding of metal/hard plastic/wood/stone/ceramic/jewelry. Pay attention. Such AB glue on copper. Aluminum. Cadmium plating material.PP and Teflon bonding is not good. Acrylic AB adhesive is generally 1:1 mixed. His temperature tolerance is around 80-100 degrees
2. Epoxy resin AB glue: The main material is epoxy resin. Room temperature curing, high mechanical strength, toughness is not as good as acrylic AB rubber, but the hardness is higher than it. The material that can be bonded is also very wide, and the result bonding can be done. However, the viscosity of epoxy resin is greatly affected by temperature, so there is no good control of acrylic AB adhesive in the process. Epoxy resin AB adhesive can also be used as potting adhesive in addition to the result bonding, especially the potting of electronic parts with high confidentiality requirements are made of epoxy resin. The resulting bonded epoxy resins are generally 1:1 mixed. According to the situation, there are 2:1, 4:1, 10:1 and other multi-medium mixing ratio. Its operating temperature is -50 ~ +180℃, and can reach +250℃ for a short time.
3. Silicone AB rubber: The main material is silicone rubber. Silicone rubber AB is mainly used in various potting. For example, LED module potting, LED lamp potting. Potting and sealing of electronic parts. Mixing ratio is not fixed, there are 10:1, 8:1 and so on. The temperature resistance of organic silica gel is relatively high, generally about 150-300 degrees.
