Addition Type Insulation Silicone Gel SI2709

?Detailed Product Description

SI2709A/B is transparent silicone gel, after cured it will be quite elastic material with buffer. 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, strong adhesive force

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

1.Use in Optical Fiber Splice Closure, waterproof junction box and underwater instrument

2.Widely used in power electronics, ignition module and potting of IGBT

Note:

?All data above were tested under standardized condition.

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

?Storage 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. The curing time is about 4-5 hours at room temperature. It also can be heating cured, will need about 30 minutes at 80?.

?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.SI2709 will be hard to cure if contact with sulfur, amine or Sn
