Compared with other types of sealants, silicone sealants are particularly durable in harsh conditions. It also has excellent uv resistance and atmospheric aging resistance, in sunlight, rain, snow and seasonal climate change and other harsh environment can keep more than 30 years without cracking, brittle, not metamorphic, in a very wide temperature range with ± 50% deformation resistance displacement ability.

Photovoltaic cell modules should be used outdoors without any protection. They should be resistant to low temperature in winter (30℃), high temperature in summer (up to 80℃ or more in the sun), rain and snow erosion and ultraviolet aging. Architectural practice has proved that silicone sealant can stand the test, so it is the most suitable sealant for solar photovoltaic cell modules.

The common silicone sealant on the market is condensed RTV silicone rubber, which will have small molecule by-product release when vulcanized. According to the type of by-products, condensed RTV silicone rubber can be divided into dealcoholization, deketoxime, deacetic acid, deamide, deacetone and other types.

In line with photovoltaic element bonding, thermal conductivity, heat dissipation and other factors greatly improve the product life and production cost, we have recently successfully developed and launched the high thermal conductivity potting adhesive to meet these conditions and high thermal conductivity effect.
