| Product Options | Primer: Applied to inhibit corrosion and to provide a suitable key for the basecoat. The choice of primer is dependent on the application and the substrate properties. Consult manufacturer's literature for more information. Topseal: Nullifire S605 basecoat can be left without topseal for 12 months, however for long term durability and external use, topseal is required. The topseal's available contain no fibres and are therefore suitable for areas where delicate electronic instruments are manufactured or used. The satin finish is easy to maintain by simply wiping clean with a damp cloth and any colour to a RAL or BS 4800 is available. |
