RTV102, RTV103, RTV106, RTV108, RTV109, RTV112, RTV116 and RTV118 one-component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure.
RTV102, RTV103, RTV108 and RTV109 sealants are standard strength paste consistency products which can be applied to vertical and overhead surfaces where pourable/self-leveling sealants are not practical. RTV112 and RTV118 sealants are self-leveling products which are preferable to pasteconsistency sealants when flow into small crevices and hard-to reach places is desired. RTV106 sealant is paste-consistency sealant. RTV116 sealant is a self-leveling sealant.
Both RTV106 and RTV116 sealants are standard strength high temperature sealants. Since all these sealants utilize a moisture cure system, they must not be used in thicknesses of greater than 6mm (1/4 in.). Where section depths exceed 6mm (1/4 in.), Momentive Performance Materials one component, addition cure or two-component silicone rubber compounds are recommended.
Key Features
- One-component products
- Capability to cure at room temperature and ambient humidity
- Self adhesion properties
- Low temperature flexibility
- High temperature performance
- Excellent weatherability and ozone and chemical resistance
- Excellent electrical insulation properties
Applications
- General purpose bonding, sealing, electrical insulation, formedin-place gaskets. Can be applied to vertical or overhead surfaces
- Sealing heating elements, gasketing, electrical insulation, and other critical bonding and sealing applications where parts must perform at high temperatures. Can be applied to vertical or overhead surfaces.
- Thin section potting, filling small surface voids, self leveling protective coating, electrical insulation where high temperature performance is required.
- Electrical insulation, thin section potting, self leveling protective coatings. Will flow into small crevices and hard to reach places.
- These sealants were not designed for and should not be used for applications intended for permanent implantation into the human body.
- These sealants are not for use in delicate electrical and electronic applications in which corrosion of copper, brass or other sensitive metals is undesirable.
