Multipurpose adhesive / sealant for the electronics industry, typical use for CIPG- and FIPG-applications.
Processing
- ELASTOSIL® N199 TRANSPARENT is a one-part room temperature vulcanizing sealant that cures to a flexible silicone rubber on exposure to water vapor in the air. During the curing process a small amount of an oxime is relea sed.
- The crosslinking starts at all places where the paste comes into contact with atmospheric moisture and proceeds from the outer to the inner parts of the silicone. After about 30 minutes a skin of cured material is formed at the surface. After formation of a sufficiently thick skin, glued parts may be handled without destruction. For the crosslinking to take place, water vapor from the air is necessary.
- For this reason the curing rate strongly depends on the atmospheric humidity in the surrounding. The higher the atmospheric moisture the faster the material will be cured fully. The temperature has a great influence on the curing rate as well. The higher the temperature the faster the material will be fully cured. 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® N199 TRANSPARENT shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application.

Safety & Health
- Safety Note
- During vulcanization of ELASTOSIL N199 TRANSPARENT, a total of 4% by weight of an oxime is being split off. These vapors should not be inhaled for long periods or in high concentration. Work areas should therefore be well ventilated.
- Contact of unvulcanized silicone rubber with eyes and mucous membranes must be avoided as this would cause irritation. However if it does happen, rinse the affected area thoroughly with water.
