A, LED drive power supply pouring sealant purpose

LED drive power supply potting glue ratio is 1:1 and now two kinds, room temperature curing or heat curing, can be as a heating element with the radiator thermal conductivity between the gap filler material, suitable for electronic parts of thermal conductivity, insulation, waterproof and flame retardant, filling and sealing high module, power module and the transformer can also be used to switch power supply, drive power supply, car HID lamp module power supply, ignition system module power supply, home appliance controller, the network transformer, etc., its flame retardant can reach UL 94 v - level 0, coefficient of thermal conductivity of 0.8 w/(m k) above, completely in line with the eu ROHS directive requirements.

Second, the pouring sealant properties LED drive power

1, excellent electric properties and heat resistance properties.

2, no corrosion, no odor, yellowing resistance, waterproof and flame retardant.

3, room temperature curing can also heat curing, curing process without shrinkage, after curing to form elastic protection.

4, excellent adhesion, copper, aluminum, stainless steel, iron, tin, PCB, ABS, PVC, PET, PBT, PC, such as Epoxy has good adhesion.

Three, LED drive power supply pouring sealant technology parameters and price

Type AB color proportion hard degree (A0) viscosity (Mpa) s operating time (min) curing time (h) coefficient of thermal conductivity of electronic potting glue price

3304 now black 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

3311 now white 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

3301 now grey 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

3300 10:1 transparent 10-15 50 to 60, 2500-3000 10-12 0.2 ~ 0.3

1301 1:1 white 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

1302 1:1 black 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

1303 1:1 gray 20 ~ 30, 6000-8000, 40-60 8-10 0.6 ~ 0.8

1300 1:1 transparent 15 to 25, 2500-3000, 50 to 60 10-12 0.2 ~ 0.3

The four, LED drive power supply pouring sealant technique parameter and price

1, the measurement accuracy: weighing A and B component, according to manufacturer instructions proportion with glue.

2, mixing: A first component mix, then add the B component with A component with glue mixed evenly in the container.

After 3, pouring: mix rubber to potting.

4, cure: potting good parts at room temperature curing, the early solid into next working procedure, after completely cured in about 1 to 2 hours. Summer temperature, curing is quicker; Can be slow to winter low temperature curing.

Five, LED drive power pouring sealant used points for attention

1, LED drive power supply potting glue injecting, best wall slowly pour down to seal glue object, easy to go to sealant for objects in the air, reduce the generation of air bubbles, note glue, glue solution will gradually penetrated into the aperture of products, if necessary, can be divided into multiple note glue, conducive to bubble, seepage.

2, LED drive power supply pouring sealant are A, B glue blend to mix use, in order to prevent curing incomplete, and in A short period of time as far as possible to use the glue liquid mixture, by mixing adhesive solution will start reaction, and gives off heat, its viscosity will gradually rise, and gradually solidified, and the more the amount of rubber mixing, release is, the more heat, the faster the reaction also, thus affect the using time, environment temperature can also affect the use time and curing time.
