Project Overview
A Canadian insulating glass manufacturer required a reliable primary sealant to withstand extreme winter temperatures as low as -40°C. After strict testing, they selected Shandong Heng Hui’s premium hot melt butyl tape. Our product provided excellent water vapor resistance and maintained strong adhesion in freezing conditions, ensuring the long-term durability of their high-performance double-glazing units.
