ZQ705 silicone
Product performance
ZQ705 is a one-component silicone rubber cured at room temperature. It has the characteristics of fast surface drying at room temperature and easy to use. This product maintains rubber elasticity in a wide temperature range (-60°C-200°C), has excellent weather resistance and electrical insulation, is waterproof and moisture-proof, shock-resistant, corona-resistant, and anti-leakage performance, and has good adhesion performance.
The main purpose
As a bonding, sealing, insulating, moisture-proof and shock-proof material, this product is widely used in bonding and sealing of electronic components, semiconductor materials, electronic appliances and other equipment, waterproofing and sealing of electric heaters, electronic instruments, and potting of electronic components Wait. Specifically, such as the sealing of electric heating ends, the bonding of small motor magnetic tiles and metal casings, the bonding and sealing of automobile lights, optical instruments and lenses, the bonding of electronic instrument casings, the insulation protection of motors, and the bonding and sealing of electronic components. Wait.

Note: All mechanical and electrical properties are tested after curing for 7 days under the conditions of 25℃ and 55% relative humidity. The performance of each type of silica gel is subject to the actual test report.
Use process and precautions
1. After the components are cleaned in general, cut the tip on the nozzle sleeve, extrude the glue, and glue it. Tack dry for 3-30 minutes. Under the environment of room temperature 25℃ and humidity 50%, the curing depth is 2-3mm in 24 hours. If the glued area is large and the glue layer is thick, the curing time will be longer. The longer the storage time at room temperature, the better the bonding effect. Due to its low strength, the glue cannot be used in places subject to large forces. It is not suitable to do large-area bonding. In this case, it is best to inject several times, wait for the first curing and then do the second infusion to solve the problem of deep curing. The necessary humidity should be ensured when this product is vulcanized, and it should not be placed in a closed place (such as an oven) immediately after the glue is applied. /2. After the operation is completed, the unused glue should be tightened immediately and sealed and stored. When using it again, if there is a little skin on the seal, just remove it, and normal use will not be affected. During the storage of the glue, a small amount of curing may also occur at the mouth of the tube. After it is removed, it can be used normally without affecting product performance. Before curing, if it gets into the eyes accidentally, seek medical attention.
