Hybrid wind tower systems
A two-component, thixotropic structural epoxy adhesive for horizontal and vertical joints between precast concrete segments in hybrid wind towers. The reviewed type-test evidence covers processing time, sag resistance, bond performance, compressive properties, shrinkage, glass-transition temperature and VOC-related items.

Technical data
“Requirement” is the stated acceptance threshold or range. “Actual result”, “typical value” and “published value” are not guaranteed minima unless the requirement column says so. Final acceptance must follow the approved TDS, report, test method and project conditions.

English technical data sheet
Prepared from the supplied Sino-sina Building Materials Co., Ltd. product manual. Requirements are kept separate from published or reported values. Use the current controlled document and project specification for final approval.
Independent test evidence
Values in the reported-result column were transcribed from independent laboratory reports supplied by Sino-sina. Public material retains Sino-sina Building Materials Co., Ltd. and, where positively verified, the testing institution and report reference; project/client identities, personnel, signatures, stamps, QR codes and contact addresses are omitted.
Photographed field method
The photographs show the adhesive pail, serrated-trowel application, a continuous ridge pattern and segment lifting. Product ratio, working time, joint temperature, coverage and final squeeze-out remain controlled inspection points.
