RTV108 - Clear Silicone Sealant

RTV103 is a one-component, ready-to-use clear sealant. It is commonly used for sealing, caulking, insulating, bonding, and formed-in-place gasketing.

This clear silicone sealant cures to a tough, durable and resilient rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure.

RTV108 has a standard strength paste consistency and can be applied to vertical and overhead surfaces where pourable/self-leveling sealants are not practical. It is an ideal product when a translucent clear silicone caulk is needed for filling cracks or gaps, or whenever a clear silicone waterproof sealant is needed.

Because it utilizes a moisture cure system, this clear silicone adhesive should not be used in thicknesses greater than 6mm (1/4 in). Where section depths exceed 6mm (1/4 in.) we recommend using Momentive Performance Materials’ one-component addition cure or two-component silicone rubber compounds.
