precote 30

Thread precoating with medium strength Description precote 30 is a varnish-like precoating system on base of microencapsulated acrylates for sealing and locking of threaded parts. The dried film is tack-free, solvent-free and physiologically harmless. Its characteristics as a sealing and locking element become effective only on assembly, when the capsules are ruptured by shear and/or pressure stress and the adhesive is allowed to cure.

Application On all threaded combinations which mainly require a sealing effect. The product can be applied on screws, studs and non-standardized  parts as well as on thread plugs and pipe threads. Due to the low strength an easy disassembly of the polymerised connection is possible.  For threads ≤ M6 or 1mm pitch we recommend precote 30-8.

Properties

• Dry and tack-free film.
• Unlosable part of the thread.
• Threaded parts can be preapplied long time before assembly(oT coating machine).
• Physiologically harmless as coating and on assembly.
• Thread friction values are not altered.
• Prevents fretting on assembly.
• Seals against pressure up to 250 bar (3600 psi).
• Avoids corrosion in the threaded connection.
• Fast curing, no postcuring even after repeated temperature exposure.
• Good chemical resistance (meets the relevant automotive specifications)
