ELASTOSIL® N 2189

ELASTOSIL® N 2189 is a non-slump, one-part Alkoxy-cure silicone sealant, which cures at room temperature under influence of moisture.

ELASTOSIL® N 2189 shows primerless adhesion to many substrates, in particular to cast magnesium. It exhibits good resisitance against mineral oils.

ELASTOSIL® N 2189 is a one-part room temperature vulcanizing sealant that cures to a flexible silicone rubber on exposure to moisture. During the curing process a small amount of an alcohol is released. Usually only minor volume shrinkage is observed. After about 15 to 25 min a skin of cured material is formed at the surface. The curing rate strongly depends on temperature and atmospheric humidity in the surrounding
After completion of the vulcanization process the product may be continously exposed to temperatures as high as 180 °C (356 °F) without damage. 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® N 2189 shows good primerless adhesion to many substrates. We recommend to run preliminary tests to optimize conditions for the particular application.
