YUHONG^™ YHMSroof-8023

Exposed Silane-Modified Polyether Waterproof Coating

YHMSroof-8023 is a single-component, solvent-free, cold-applied, moisture-cured, silane-modified polyether waterproof coating. It utilizes acrylic hybrid silane-modified polyether as the base polymer, combined with special additives, fillers, pigments, and catalysts. Its most notable feature is the single-layer moisture-curing mechanism, which forms a 2.0mm-thick film in one application, enabling the product to function as a multifunctional waterproofing solution for waterproofing, sealing, and crack-filling, such as cool roof coating, bonding adhesive for fleece-backed TPO membrane, and detailing work as crack-filling or membrane termination. The extremely low VOC property enables it to be suitable for applications with limited ventilation or sensitivity to odor
