Application details

Multipurpose sealant and adhesive for general industry and electronics for FIPG applications. Particularly suitable as
adhesive on cured rubber or silicone coated textiles like seam sealing.

Processing

ELASTOSIL® E43 is a ready-to-use, one-part silicone rubber which starts curing when exposed to air moisture. Typical
curing characteristics are given in the table "Properties Uncured".

As RTV-1 silicones require humidity for curing, free access of air moisture to the silicone rubber is essential. Additionally, the
vulcanization time of ELASTOSIL® E43 can be greatly reduced by increasing the level of air's relative humidity. Please note
that, unlike the initial skin formation, the total curing rate of RTV-1 silicones is limited by moisture's diffusion speed in
silicone rubber.

As increasing the curing temperature has just a minor effect both on the skin forming time and the curing speed,
ELASTOSIL® E43 typically is vulcanized at room temperature. Heat curing is recommended only for applications where the
silicone rubber is applied as a thin film (thickness less than 0.5 mm), because otherwise blistering is likely to occur due to
the quick release of acetic acid.

After completion of the vulcanization the silicone elastomer may continuously be exposed to constantly changing climatic
conditions, UV radiation and high temperature without damage. Cured ELASTOSIL® E43 usually shows good primerless
adhesion to many substrates, e.g. glass, ceramics, metals, plastics and powder coatings.

Removal: If removal of the silicone from machines or dispensing equipment is necessary, white spirit or similar nonpolar
solvents are recommended. However, cleaning ideally should take place before the silicone rubber is fully vulcanized. Cured
silicone needs to be rubbed off or removed mechanically, if necessary in combination with a swelling agent (solvent) or a
chemical silicone remover ELASTOSIL E43 shows good primerless adhesion to many substrates. We recommend running
preliminary tests to optimize conditions for the particular application.
