Carbon black plays a crucial role in insulating glass sealants

To achieve good sealing in insulating glass, sealants are essential. High-quality, well-sealed sealants must contain carbon black as an additive. The following article explains why carbon black is so crucial in sealants.

Insulating glass sealants are a new generation of green, environmentally friendly sealing materials, developed in response to national policies promoting high efficiency, energy conservation, sealing, and environmental protection in construction projects. Therefore, insulating glass sealants have relatively high requirements for carbon black. Only high-performance carbon black products can meet these requirements.

The performance analysis of insulating glass sealants requires consideration of the following factors:

1) Gas leakage resistance;

2) Water vapor penetration resistance;

3) UV resistance;

4) Water seepage resistance;

5) Adhesive system, i.e., structural integrity.
