Hylosil 102 Black RTV Silicone Technical Data Sheet

HYLOMAR 102
Amine curing RTV silicone sealant
Description
Hylomar Silicone Sealant 102 is a non-corrosive, low odour Room Temperature Vulcanising (RTV)
silicone compound. It is a high performance engineering grade which is used in the automotive
industry and for general manufacturing. It can also be used for a variety of applications and is
particularly suitable for high strength applications in odour sensitive environments.
Hylomar Silicone Sealant 102 has good resistance to oils and aqueous anti-freeze agents
Unlike general-purpose silicone sealants, Hylomar Silicone Sealant 102 contains no solvents and
does not evolve acetic acid during cure.

Instructions for Use
Ensure both surfaces to be bonded are clean, dry and free from contamination such as oil or
grease. The compound can be applied to form any size or shape of gasket.
Apply a bead directly onto one surface. Once applied, the joint should be assembled without
delay.
Care should be taken to ensure any excess compound does not extrude internally and foul any
internal oil-ways or other channels and cause blockages.
Any excess external product can be wiped away with a damp cloth.
Typical Applications
Due to its good resistance to oils, Hylomar Silicone Sealant 102 is ideal for use as a flexible gasket
or flange sealant, for use in automotive and general engineering applications.
