Preparation procedure.
Copper Brass Bronze and alloy.
All surfaces should be clean and free of oily or silicone contaminates. This is a constant through all Nyalic
®
applications.
Any mediums used in the polishing process should be removed completely prior to coating.
Cleaning can consist of acid dipping and neutralising washes. Even to sanding and further buffing with a cloth wheel.
If metal polishes are to be used be aware that the use of these polishes can drive oily residue and polish contents beyond the surface… here they may not be able to be removed and in so doing, making the polished object unable to be Nyalic
®
coated.
Once cleaned to the condition as required then wipe down with denatured alcohol to remove oily residues
The application of heat is beneficial in both ‘sweating out’ the moisture and contaminates from microscopic fissures found in these alloys - in any case do not heat the object above 46 deg c..
• Do not apply Nyalic ®
to a surface that temperature exceeds 55 degrees c.
• Heating the object eg. A bronze propeller prior to and after application of Nyalic ® hastens curing considerably.
• The use of a heat gun to warm brass work and copper etc is also beneficial to curing and application of Nyalic
®
.
For all immersed situations a minimum of three coats of Nyalic
®
is recommended.
Ensure complete curing of Nyalic
®
prior to putting back into service. For propellers and out-drives etc., allow at least 1 week prior to immersion and heat curing is advisable in these situations
