PACKAGING

300ml in cartridge * 24 per box, 590ml in sausage *20 per box

Storage And Shelf Life

SV999 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.

Cure Time

As exposed to air, SV999 begins to cure inward from surface. Its tack free time is about 50 minutes; the full and optimal adhesion depends on the sealant depth.

Specifications

SV999 is designed to meet or even exceed the requirements of:

Chinese national specification GB/T 14683-2003 20HM

Technical Services

Complete technical information and literature, adhesion testing, and compatibility testing are available from Siway.
