- Application Details
- Low viscous grade suitable as general purpose sealant for coating and potting, furthermore perfectly suited for screen printing applications for gaskets e.g cylinder head gaskets
- ELASTOSIL® A59 GRAY is a one-part room temperature curing coating therefore the curing rate depends on temperature and on atmospheric humidity. The curing rate can be accelerated by heat exposure or exposure to carbon dioxide concentration above 1% p.b.v.
- Uncured or partially cured silicone can be removed by help of organic solvents such as aliphatic or aromatic hydrocarbon cleaning should take place before the rubber is fully cured. Once completely cured, only mechanical removal supported by prior solvent swell is possible.
- Swelling can be accelerated by elevated temperature. We recommend running preliminary tests to optimize conditions for the particular application.

Safety & Health
- Safety Notes
During vulcanization of ELASTOSIL® A59 GRAY, a total of 3-4% by weight of an amine 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.
