Adhesives offer many advantages over other binding techniques: they facilitate the binding of different materials, they distribute stress across the joint more efficiently, they are often more cost-effective, they improve the esthetic outcome, and they increase design flexibility.
Unfortunately, adhesives also have several disadvantages, including decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during provisional testing.
Thankfully, adding colloidal silica dispersions to water-based adhesive formulations helps overcome a number of these disadvantages.
Depending on the specific application, colloidal silica can be added to improve heat resistance and shear strength and to reduce drying time. In addition, colloidal silica can be used to adjust the viscosity of adhesive formulations, without needing additional thickeners.
