Transparent Silicone Gel For Electronics Potting SI2715

◆Detailed Product Description

SI2715A/B is two component transparent self healing silicone gel, after cured it will be quite elastic material with buffer and self recovery. It’s used to isolate moisture and other noxious pollutant from contacting the circuit board, also used to dielectric of high voltage. The other usage is stress relief for protecting circuit and contact device from high temperature and mechanical stress.

Features 

1.1:1 addition type, good adhesive strength and self-healing

2.Superior elasticity for stress relief

3.Quite low oil penetration after cured, good anti-poisoning

4.Good dielectric in high temperature, protect from high voltage

5.Excellent age resistance and weather resistance

6.Excellent waterproof, corrosion prevention, moisture proof and chemical media resistance

Usage

Use for semi conductor, connector, sensor potting and encapsulating.

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 datasheet for special items.

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

◆Operation Attention

1.Mix Part A and Part B by 1:1, pour directly into the protection needed component(or module).

2.Still the potted component to let it discharge the bubble. It can cure in short time, about 30mins in 80℃. It also can be cured under room temperature, it needs about 4-5hours.

◆Notice

1.Vacuum defoamation can provide the property of cured product

2.The Mixed glue should be sealed after using

3.Low temperature will slow the curing speed, advice to heat curing

4.SI2715 will be hard to cure if contact with sulfur, amine or Sn
