1. Thickener
The high specific surface area and special structure of fumed white carbon black enable it to effectively increase the viscosity in silicone sealant and improve the rheology of the product, thereby providing better application performance.
2. Enhance Performance
By increasing the cohesion of the colloid, fumed white carbon black can improve the mechanical strength, tear strength and tensile strength of silicone sealant, enhancing the durability of the final product.
3. Anti-settlement
The dispersion of fumed white carbon black helps prevent fillers from settling during production and storage, thereby maintaining product consistency and stability.
4. Improve Touch Feeling
In some applications, fumed white carbon black can improve the feel of silicone sealant, making it smoother and easier to apply.
5. Reduce Shrinkage
The addition of fumed white carbon black can reduce the shrinkage of the colloid during the curing process and improve the dimensional stability of the finished product.
6. Prevent Bubbles
Vapor-phase white carbon black can effectively control foam generation during the mixing process, ensuring that the colloid will not product bubbles that affect the effect when used.
7. Promote Curing
In some formulations, fumed white carbon black can work with other ingredients to speed up the curing of silicone sealant.
