AI Technical Summary
Existing single-component de-alcoholized silicone sealants are prone to stringing during application, which makes application inconvenient and causes the sealant joints to be easily contaminated by the stringing residue, reducing construction efficiency and increasing the cost of the sealant.
A modifier was prepared by reacting tris[3-(trimethoxysilyl)propyl] isocyanurate with hydroxymethyldiphenylsilane, and then reacted with nano-calcium carbonate to prepare modified nano-calcium carbonate, which was used in a one-component de-alcoholized silicone sealant to reduce the internal adhesion of the sealant.
It significantly improves the stringing resistance of silicone sealant, avoids adhesion, trailing and contamination during application, improves construction efficiency and aesthetics, and reduces adhesive waste and cost.
