- Description
- Technical specification
LOCTITE® SI 5015 is a blue, 1-part RTV (room temperature vulcanizing) acetoxy silicone paste which cures at room temperature on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. This product resists aging, weathering and thermal cycling without hardening, shrinking or cracking. Ideal for stamped parts and safe for use with automotive oxygen sensors. Typical applications include use in valve covers, timing gear covers, differential covers, oil pans, transmission pans, water pumps and thermostat housings. This product is typically used in applications with an operating range of -54 °C to 204 °C.

How to use
For best performance bond surfaces should be clean and free of dirt, dust, oil and any other contaminants.
Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed.
Excess (uncured) material can be easily wiped away with non-polar solvents. Remove cured material using a knife or single edge razor blade.
The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads
LOCTITE® SI 5015 is not recommended for use as a cylinder head gasket or head gasket sealant.
