Two Component Silicone Potting Compound For Electronics SI2225 

◆Detailed Product Description

Features

1.SI 2225A/B is used for encapsulating and potting varied electronic components. It can vulcanize to deep layer. The two components have a good fluidity after mixing. You can adjust the proportion of curing agent while operating. It’s primerless and bonding well with most materials. It can be used to fix the accessories and resist water, dust and leakage current.

2.Double component high clarity liquid silicone adhesive, condensation dealcoholization.

3.Low viscosity, easy to process and operate.

4.Low hardening condensation, no corrosion and unstressing.

5.Excellent insulativity and stability in high temperature.

6.Excellent bonding, good water-proof and moisture-proof.

Usage:

1.Electronic and modules of automobile potting.

2.Power control module potting .

3.LED display screen potting .

4.LED spotlight, led wall washer, Broad Area Linear Lights and fluorescent lamp.

Note:

①All data above were tested under standardized condition.

②All data listed in the chart were for the generalized item in the series; please refer to the related data sheet for special items.

③Storage condition has a direct impact to the products’ shelf life, Please refer to the instruction for special items’ storing.

◆Operation

1.Mixing uniformity in the packing before using.

2.Maxed A, B component as the weighing ratio of 10:1, mixing, and injected to the protection components (or modules) which need potting directly. In order to reduce the bubbles, injected slowly along the walls of the implement..

3.Let the components sit,out of bubble by themselves,heat curing or curing in the room temperature after the bubble disappeared,need about 1-6hours.

4.About potting equipment please contact our Marketing Department

Note:

1.It can improve the performance of the hardened by vacuum defoaming for mixed component.

2.After use, please seal the package.

3.The curing speed will be slow in the low temperature, suggest workshop in constant temperature.The temperature is too low will lead curing speed Pianman, the proposed workshop thermostat

4.Once SI2225 contact with sulfur, amine, tin material would be difficult to sclerosis.
