PRODUCT INTRODUCTION
CURE TIME
As exposed to air, SV628 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
SV628 is designed to meet or even exceed the requirements of:
Chinese national specification GB/T 14683-2003 20HM
STORAGE AND SHELF LIFE
SV628 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
HOW TO USE
Surface Preparation
Clean all joints removing all foreign matter and contaminants such as oil, grease, dust, water, frost, old sealants, surface dirt, or glazing compounds and protective coatings.
Application Method
Mask areas adjacent to joints to ensure neat sealant lines. Apply SV628 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the joint surfaces. Remove masking tape as soon as the bead is tooled.
TECHNICAL SERVICES
Complete technical information and literature, adhesion testing, and compatibility testing are available from Siway.
SAFETY INFORMATION
