Product Information


As exposed to air, SVmildewbegins to cure inward from surface. Its tack free time is about 50 minutes; the full and optimal adhesion depends on the sealant depth.


SVmildewis designed to meet or even exceed the requirements of:

Chinese national specification GB/T 14683-2003 20HM


SV mildew should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
