Hylosil 106 Ivory RTV Silicone Technical Data Sheet

HYLOSIL 106
Amine curing RTV silicone sealant
Description
Hylosil 106 is a non-corrosive, low odour (when compared with Acetoxy based sealants), Room
Temperature Vulcanising (RTV) silicone compound. The product 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 other applications and is particularly suitable for high strength applications.
Hylosil 106 has a high viscosity, which gives an immediate low pressure seal when the joint is
assembled. It has good resistance to oils and aqueous anti-freeze agents. Unlike general-purpose
silicone sealants, Hylosil 106 contains no solvents and does not give off acetic acid during cure.

Instructions for use
Ensure both surfaces to be bonded are dry and free from contamination such as oil or grease.
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, Hylosil 106 is ideal for use as a flexible gasket or flange sealant,
for use in automotive and general engineering applications. Due to its non-sag properties the
product is ideal for application to vertical surfaces.
