JW-3715 Two component silicone sealant
JW-3715 is a two-component room temperature vulcanized silicone rubber. It is a special sealant specially designed for solar frame components and other electronic and electrical industries. The A/B components can be quickly cured after mixing, which can meet the requirements of fast glue cleaning and fast entering the next assembly after sizing and assembly. It has excellent adhesion performance to aluminum alloy, steel, glass, plastic and photovoltaic backplane.
This product is recommended to be used for solar photovoltaic module frame sealing, junction box bonding, bracket bonding.
Features
- Fast curing.
- Good adhesion to the glass, metal and composite materials.
- Passed the double"85"high temperature and humidity test, aging test, hot and cold temperature impact test.
- Passed UL certification, certificate No:E539098.
