ASTM C920 GB Compliant Two - Component Sealant For Insulating Glass Edge Sealing
Features:
As a dual-component, neutral-setting sealant, CSJ-9900 relies on a two-component rubber beater, where the mixing ratio modulates the curing time. It showcases high performance, flexibility, ozone durability, and corrosion immunity.
Basic Uses:
Sealing off the secondary edge of insulating glass in structural glazing applications.
Specification:
Operating conditions of 23±2°C and 50±5%RH, then test:
