Hurricane-Resistant Sealant for Glazing
National Starch and Chemical Company has developed a specialty sealant that will allow windows to be manufactured to better resist hurricane-force winds and impacts from wind-borne projectiles.
Windows glazed with the PURFECT GLAZE polyurethane hot melt sealant have been subjected to ASTM tests for weathering, water resistance, structural performance, and impact under extreme conditions. The tests also followed procedures set by Dade County, Florida. Test data show that after 24 hours the strength of PURFECT GLAZE adhesives exceeds 400 psi, far in excess of current backbedding options. More than three quarters of this strength is realized within the first three hours.
