ELASTOSIL® N2197 GREY
ELASTOSIL® N2197 GREY is a one-part, nonslumping silicone sealant which cures to a permanently flexible silicone elastomer on exposure to moisture.
ELASTOSIL® N2197 GREY is a ready-to-use, acid- and solvent-free, non-corrosive RTV-1 (room temperature vulcanizing, one-component) silicone rubber suitable for many applications.
Excellent adhesion to plastics and metals in combination with a high elasticity and durability open up a wide range of potential uses for <(> <<)>productname>. Seals made from ELASTOSIL® N2197 GREY exhibit an outstanding resistance to weathering, ageing, moisture, and UV light. The fully cured rubber can withstand expansion-compression cycles for many years and is therefore especially well suited for joining materials with different coefficients of thermal expansion. The vulcanized silicone rubber permanently remains elastic over a wide temperature range from -50 °C to +180 °C (-58 °F to +356°F).
- neutral curing system (alkoxy)
- excellent unprimed adhesion to many plastic, metal, glass, and ceramic surfaces
- flame retardant: meets UL94 V-0
- ELASTOSIL® N2197 GREY meets the physical requirements of MIL-A-46146, Group I, Type I
- general-purpose adhesive for technical applications
ELASTOSIL® N2197 GREY is a one-part room temperature vulcanizing sealant that cures to a flexible silicone rubber on exposure to moisture. The curing rate strongly depends on temperature and atmospheric humidity in the surrounding. During the curing process a small amount of an alcohol is released.
If removing of silicone rubber from machines or dispensing equipment is necessary, white spirit is recommended as a solvent. However, cleaning should take place before the rubber is fully cured. Afterwards only the use of mechanical forces in combination with a swelling solvent or the use of high temperatures of approximately 100°C will help to remove sealant residues.
ELASTOSIL® N2197 GREY shows good primerless adhesion to many substrates. We recommend to run preliminary tests to optimize conditions for the particular application.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
