Thixotropic Agent for PU Sealant

This Thixotropic Agent for PU Sealant functions by forming a three-dimensional network within the polymer matrix, increasing viscosity at rest while maintaining flow during extrusion. It improves shape retention and prevents dripping, sagging, or cracking after application. Compatible with moisture-cure and high-solid PU sealant systems, it offers excellent stability under temperature and humidity variations. The additive enhances mechanical integrity and provides smooth surface finishing, making it ideal for automotive, construction, and industrial sealing applications.
