ELASTOSIL® N 2034 is a self-levelling, Alkoxy-cure one-component silicone sealant, which cures at room temperature under the influence of moisture.

It shows excellent primerless adhesion to many substrates.



  • flame retardant (meets UL 94 V-0)
  • self-levelling
  • Recommended service temperature from -45 °C to +180 °C

Specific features of ELASTOSIL® N 2034

  • Flame retardant
  • Low viscosity
  • One-component

Multipurpose grade for sealing and bonding such as FIPG-applications for e.g. automotive headlamps

ELASTOSIL® N 2034 is a ready-to-use, acid- and sovent-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 ELASTOSIL® N 2034. The consistency of the uncured material allows a high application rate and makes it a good choice not only for dispensing from a caulking gun but also for automatic dispensing. 

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).

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.

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.
