Primer
Description
This is a specially formulated silicone based primer for use with a
wide range of CHT 1K Condensation / Moisture curing RTV
silicone sealants. This primer imparts good adhesion to most
metals. It is recommended as a primer for use on non-porous
surfaces. For all new applications, it is recommended that
customers carry out small-scale tests to determine the suitability
of the primer and the strength of bond produced.
Key Features
Aerospace approved
Suitable for use with CHT adhesives
Suitable for non porous surfaces
For use with most metals
Key Applications
Rolls Royce MSRR1064
Application
Primer for condensation cure 1 part adhesives on metal
substrates. Not suitable for polycarbonate and acrylic
Use and Cure Information
This primer contains solvents which are classified as hazardous
under current regulations. Users should read the Safety Data
Sheets for this product carefully before use. Surfaces to be
bonded should be dry and free from grease, oil, dust and release
agents. Non-porous substrates, should be solvent degreased prior to application. The primer should be applied with a lint-free cloth or
paintbrush and allowed to dry thoroughly at room temperature for a minimum time equal to the tack free time given in this document, before
applying the sealant. Drying should be carried out in a well-ventilated area. Do not leave longer than 2 hours. The drying/curing time is
dependent on the ambient temperature and humidity. Heat should not be applied to accelerate the drying cycle. Over-application of the
primer will result in poor adhesion. As a guide, one litre of Primer should be sufficient for approximately 15 m . It is absolutely important to
check the compatibility in preliminary tests if unknown substrates are used.
