| Description and Operation 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sanded bare before applying stopper. 1-component nitro-combination stopper Nitro-combination stopper has mostly been superseded by 2-component polyester stopper.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 CAUTION:Do not exceed the quantity of hardener specified by the manufacturer, excess peroxide can cause staining of the paint top coat. CAUTION: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 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 - P240 | | Application | 2-component polyester glass fiber stopper | | Use | Equalization of unevenness; blending in of vehicle extensions; repair of GRP components | | 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 | 2-component polyester fine stopper should always be applied after 2-component polyester glass fiber stopper. | Application | 2-component polyester spray stopper | | Use | Equalization of unevenness | | Hardener quantity | approx. 3 - 5% | | Working time | approx. 25 - 30 minutes | | Layer thickness | 200 µm or 4 - 8 spray passes | | Drying | 20°C approx. 3 hours | | | Short wavelength infrared approx. 10 minutes | | | Medium wavelength infrared approx. 15 - 20 minutes | | Sanding tool | Eccentric, sanding disk by hand | | Grade | P80 - P150; fine sand - P280 | | Application | 2-component plastic stopper for flexible thermoplastic | | Use | Equalization of scratches or unevenness | | Hardener quantity | approx. 3 - 5% | | Working time | approx. 25 - 30 minutes | | Drying | 20°C approx. 15 - 30 minutes | | | 60°C approx. 15 min | | | (Short wavelength infrared approx. 8 minutes)* | | | (Medium wavelength infrared approx. 8-10 minutes)* | | Sanding tool | Eccentric, sanding disk by hand | | Grade | P80 - P150; fine sand - P280 | *Infrared drying may adversely affect adhesion, therefore check the manufacturer's instructions. Plastic stopper has a very great tendency to shrink back, so that the edge of the stopper repair becomes visible. Plastic stoppers are flexible and universally applicable on all types of plastic (except for pure PE and PP, these are plastics which cannot be painted). The manufacturer's instructions must be very exactly followed in order that no adhesion problems occur. A special plastic etch primer is specified for some materials. Primers | Application | 1-component primer | | Use | Isolation of bare sanded areas. | | Spray gun | HVLP 1.3 mm | | Spray pressure | 2.0 bar | | Drying | 20°C approx. 15 - 20 minutes | | | 60°C approx. 10 min | | Coat application | Wet on wet, no intermediate sanding | | Application | 2-component primer | | Use | Corrosion protection and bonding agent (steel sheet, zinc coated steel sheet, aluminum) | | Spray gun | HVLP 1.3 mm | | Spray pressure | 2.0 bar | | Drying | 20°C approx. 15 - 20 minutes | | | 60°C approx. 10 min | | Coat application | Wet on wet, no intermediate sanding | HS primer filler and HS tinted filler Note: - Primer filler is available as 1-component and 2-component water based and solvent based forms.
- 1-component products are only suitable for isolation of sanded through bare areas and new painting.
- Water based products are also used for the skinning of thermoplastics and substrates which are sensitive to solvents.
- Tinted fillers can be individually matched to the top coat color and therefore find uses in effect paints and paints with poor covering power.
- Use dry sand or wet sand filler according to application in order to avoid unnecessary sanding work.
- On critical substrates the use of epoxy resin base filler is recommended in order to avoid adhesion problems.
| Application | HS primer filler and HS tinted filler | | Use | Equalization of unevenness, edge zones, sanding scores | | Spray gun | HVLP 1.6 - 1.9 mm | | Spray pressure | 2.0 bar | | Layer thickness | 50 - 70 µm to 150 µm possible | | Drying | 20°C approx. 2.5 hours | | | (60°C approx. 25 min)* | | | (Short wavelength infrared approx. 8 minutes)* | | | (Medium wavelength infrared approx. 10-15 minutes)* | | Coat application | Wet on wet, no intermediate sanding | *In order to avoid boiling out, drying should be performed slowly.
