August 15, 2024 – Calcium carbonate plays a pivotal role in the adhesives industry. By incorporating an appropriate amount of calcium carbonate powder, the adhesive properties and stability of glues can be significantly enhanced. The microfine structure and porous nature of calcium carbonate increase the contact area between the adhesive and the material being bonded, thereby bolstering the bonding strength. Additionally, it has the capability to undergo physical or chemical reactions with other components in the adhesive, resulting in a more robust bonding structure.
In the context of polyurethane adhesives, the introduction of calcium carbonate contributes to greater colloidal stability. It improves the dispersion of water within the colloid and enhances precipitation stability. Furthermore, it aids in reducing the viscosity of the colloid, ultimately leading to cost reduction. This discovery has made calcium carbonate a prevalent choice as a filler for polyurethane adhesives.
According to AsiaMB, polyurethane adhesives constitute a crucial category among synthetic adhesives, distinguished by their strong bonding power and excellent low-temperature resistance. These adhesives find widespread applications across various industries. With the continual advancement of technology, the performance of polyurethane adhesives is undergoing constant improvement to cater to the demands of diverse application scenarios.
Moreover, the application of calcium carbonate in adhesives extends beyond polyurethane adhesives. It can also be employed in other types of adhesives to elevate their performance. As the chemical industry continues to evolve, the prospects for calcium carbonate in the field of adhesives appear even more promising.
