Momentive RTV118 is a versatile, ready to use adhesive sealant which cures to a tough, durable resilient silicone rubber. Uncured, this general purpose sealant is a self-levelling product which is more preferable to other sealants with a paste consistency when using it to flow in to small crevices and hard to reach places.
RTV118 will bond to many clean surfaces without the aid of primers. These surfaces typically include many metals, glass, ceramic, silicone rubbers and some rigid plastics. For difficult-to-bond substrates, the use of a primer is suggested. Depending on the substrates involved, various primers are recommended for use with these sealants, specifically SS4004, SS4044 and SS4179.
This product is suited for a range of applications including general purpose bonding; sealing; electrical insulation and creating formed-in-place gaskets.
