501-36-35 Paint - General Information 501-36-35 DESCRIPTION AND OPERATION Refinishing Materials The manufacturer's instructions must always be followed when dealing with all materials! The information given in the following text is data which is independent of the manufacturer, and it should only be used as an indication. Stopper materials ‡ 1-component nitro-combination stopper ‡ 2-component polyester stopper ‡ 2-component plastic stopper Use suitable primer to protect from corrosion areas which have been sanded bare before applying stopper. 1-component nitro-combination stopper Nitro-combination stopper has mostly been superseded by 2-component polyester stopper. Fast drying fine stopper for the smoothing of irregularities. The working properties of 1-component nitro-combination stopper can be improved by the addition of nitro thinners. Drying time increases with thickness of the layer. Application 1-component nitro- combination stopper Layer thickness Max. 80 µm Drying time up to 2 hours at 20°C Sand P240 - P400 2-component polyester general stopper CAUTIONS: Do not exceed the quantity of hardener specified by the manufacturer, excess peroxide can cause staining of the paint top coat. Mix the stopper base and the hardener well to avoid a marble-like effect. Check that the manufacturer permits use on the substrate to which it will be applied. 2-component polyester stopper is available in coarse and fine grades. The coarse stopper can be used for very uneven areas and surfaces and fine stopper or spray stopper should be applied afterwards. Application 2-component polyester coarse stopper Use Rough equalization of unevenness Hardener quantity approx. 3 - 5% Working time approx. 4 - 6 minutes Drying 20°C approx. 12 minutes Short wavelength infrared approx. 4 minutes Medium wavelength infrared approx. 5 - 10 minutes Sanding tool Eccentric, sanding disk by hand Grade P80 - P150 Application 2-component polyester fine stopper Use Equalization of uneven- ness Hardener quantity approx. 3 - 5% Working time approx. 4 - 6 minutes Drying 20°C approx. 12 minutes Short wavelength infrared approx. 4 minutes Medium wavelength infrared approx. 5 - 10 minutes Sanding tool Eccentric, sanding disk by hand Grade P80 - P240 Application 2-component polyester glass fiber stopper Use Equalization of uneven- ness; blending in of vehicle extensions; repair of GRP components Hardener quantity approx. 3 - 5%
