1 Part RTV silicone adhesive sealant paste non corrosive
Introduction
This is a non-corrosive, neutral cure, 1-part, RTV (Room
Temperature Vulcanising) silicone adhesive sealant. It is one in a
range of Acetone cure products which are solvent free. It exhibits
excellent primerless adhesion to many substrates and cures
rapidly at room temperature when in contact with atmospheric
moisture to form a tough rubber. This product will not corrode
copper or its alloys and is suitable for use with electronic
components.
Key Features
Non-corrosive
Good spreading and tooling properties
Fast skinning
Good adhesion to most substrates
Use and Cure Information
This product is a ready for use 1 Part system. If supplied in
cartridges it can be applied using either manual or pneumatic
dispensing guns. It can also be applied from bulk containers using
conventional drum dispensing equipment.
All surfaces to which the sealant is to be applied should be clean,
dry and free from grease, dirt, and loose material. Priming of
surfaces is not normally required. If using as an adhesive, it
should be applied to one clean surface and the other clean
surface brought into contact with it within the tack free time stated
opposite. For optimum bond strength, the thickness of the sealant
joint should be a minimum of 1 mm.
The sealant will cure upon exposure to atmospheric moisture,
ideally between 20 to 30 ºC and 40% to 70% Relative Humidity.
Time taken for cure will depend on the thickness of the joint,
humidity and temperature. Joints should be left undisturbed for at
least 24 hours, but preferably longer to effect sufficient depth of
cure. Full cure requires 7 days.
“For pneumatic dispensing of 310 ml cartridges, the
recommended pressure is 2.25 to 3.45 bar (40 to 50 psi).
Dispensing pressure above the recommended limits may lead to
gas bypassing the piston, causing spluttering at the nozzle and
poor bead quality”
