Usage and precautions:
* because the colloid contains fillers and heat conducting materials, the colloid placed for a long time will be layered and the filler will precipitate. Before use, mix the A / B components evenly, and then put them into the mixing tank according to the mass ratio of 10:1.
* pour the mixed rubber into the device to be potted. Generally, vacuuming is not necessary. If conditions permit, it is recommended to refill after vacuuming. This product is room temperature curing type. The curing speed of adhesive has no great relationship with curing temperature, but has a great relationship with the proportion content of agent B. the larger agent B is, the faster the curing speed is (it is suggested that the adjustment range of agent B is 100:7-100:12). Generally, it takes about 24 hours to cure at room temperature, and more than 72 hours to cure completely.
* Unused rubber materials shall be sealed for storage. The storage period is 6 months (25 ℃). The mixed rubber should be used up once to avoid waste.
* this product is not dangerous, but it is not allowed to enter or eyes.
* transportation: no domestic (cn-gb), International (IMO, IATA, UN) regulations. Non dangerous goods.
* 22kg / group
* component a of this product is black viscous liquid and component B is translucent liquid. The two components can be preserved for a long time before mixing.
This product has good fluidity, cohesiveness, insulation, elasticity, corrosion resistance and weather resistance. After curing, the colloid can be used in a wide temperature range. During curing, ethanol molecules are released, which will not cause corrosion to PC, PP, ABS, PVC, copper wire and other materials. It has good adhesion to most electronic accessory materials (except PP and PE).
* without shrinkage during curing, it has good waterproof, moisture-proof and anti-aging properties.
Requirements for environmental protection:
* comply with the EU ROHS directive.
* scope of use:
＊ & nbsp; is mainly used for automatic filling and sealing of the machine directly inserted into the display screen, which plays the role of waterproof and moisture-proof bonding.
