Momentive IS808, IS803, IS802 one-component, ready-to-use silicone adhesive sealants have a paste-like consistency and cure to silicone rubber on exposure to atmospheric moisture at room temperature. Because these paste-consistency products will flow only with external pressure, they may be applied to horizontal, vertical and overhead surfaces in thicknesses up to 6mm (1/4 in.) They have sufficient uncured body to adhere small objects while cure is taking place. IS800 Series adhesive sealants utilize a moisture vapor cure system and release acetic acid vapours from the sealant surface as a by-product of cure.
The following products are identical materials, differing only in colour:
Momentive IS802 – White
Momentive IS803 – Black
Momentive IS808 – Translucent
