One-component, moisture-curing polyurethane adhesives used for elastic bonding in construction, industrial assembly and automotive applications require strength and flexibility. YK-SIL fumed silicas impart thixotropy in adhesives, enabling the adhesives to shear-thin for easy dispensing and application, yet be non-sagging and have stable bond lines until cured. Treated fumed silica can enhance mechanical properties of the cured adhesive, resulting in greater tensile strength, elongation and shear strength.
