JS-1184
Sealing adhesive for the junction box of solar photovoltaic modules

The main function of the photovoltaic module junction box is to connect and protect the solar photovoltaic module, conducting the current generated by the photovoltaic module. The junction box of solar photovoltaic modules often needs to be sealed, which plays a waterproof and moisture-proof role in diode heat dissipation and bypass.

JS-1184 solar photovoltaic module junction box sealing adhesive is an organic silicon two component condensation type sealing adhesive. This product has the characteristics of no heat release, no corrosion, low shrinkage rate, and fast curing speed during curing, and is suitable for thermal conductivity, sealing, insulation, etc. of various electronic components.

Product features

1. Room temperature curing, fast curing, high production efficiency, and easy to use;

2. Maintain rubber elasticity over a wide temperature range (-40 ℃~150 ℃), with excellent electrical properties and good thermal conductivity;

3. Waterproof and moisture-proof, resistant to chemical media, resistant to yellowing, and weather aging for more than 25 years;

4. Good adhesion to materials such as PC, PVC, ABS, PPO, etc;

5. Passed UL certification in the United States with certificate number E335227;

6. Fully comply with the EU ROHS environmental directive.

The above performance data after curing are all measured at 23 ± 2 ℃ and a relative humidity of 50 ± 5% after 7 days of curing
Operation and Safety
  • The performance data after curing above are all measured at 23 ± 2 ℃ and a relative humidity of 50 ± 5% after 7 days of curing. Operation method:
  • 1. Clean the sealing surface and remove oil stains.
  • 2. To ensure the uniform distribution of the filler, mix component A evenly before use.
  • 3. If manual mixing is used, weigh components A and B according to the ratio and mix evenly in the mixing tank. Uneven mixing will affect the appearance and insulation performance of the cured product.
  • 4. The sealed parts are cured at room temperature, and after initial solidification, they can enter the next process. It usually takes about 3 hours to cure at room temperature. High temperatures in summer lead to faster curing; When the temperature is low in winter, the curing will be slower.
  • 5. It is recommended to use specialized sealing equipment for gluing.
  •  注意事项
  • 1、粘结材料表面有油状物或其他杂质,用适当的溶剂例如酒精、丙酮等溶剂清洗;
  • 2、未固化密封胶不可接触眼睛,若不慎接触,请用水冲洗,并及时就医;
  • 3、请避免长时间接触皮肤,否则可能引起发痒。
