- Spray or brush on to the substrate.
- Laser Mask 5900 is thick gel type coating. initially it will not look smooth.
- After a few minutes Laser MASK will flow smooth and consistent.
- Drying time is 20-30 minutes.
- After complete drying, engrave and cut the substrate. Peel the Laser_ProtectMask off to reveal the clean substrate. Non hazardous and laser safe.
Standard air assisted, or airless spray equipment, Brush or Roller (Use lambs wool roller).
Using standard good atomizing spray equipment (eg. DeVilbiss MBC gun, FF nozzle and No 765 air cap) with pressure feed, a 100 micron (0.004″) film can be applied to a vertical surface in one coat. Atomization pressure of 5ATM (75lbs/sq in) and sufficient pot pressure (0.3 ATM – 5lbs/sq in) to obtain proper fluid delivery is recommended. Airless spray can also be used such as Graco No 205-904 with a 163-168 insert and a 28:1 ratio pump. Use water only for cleaning spray equipment. Drying can be accelerated by circulation of warm air or infra red lamps.
When spraying over freshly lacquered or re-enameled surfaces, allow 24 for lacquer to dry and allow full enamel cure before applying peelable coatings. Be sure to apply full film thickness of 100 microns (0.004″). On equipment to be stored for many months exposed to rain, sun and snow, it is recommended that a 200 micron (0.008″) film of Strippable coating be applied in two coats, drying one hour between coats. This is a water based compound and should be protected from freezing. Recommended storage temperature is 10o°C-32o°C.
Try to avoid ‘feather edges’ or areas where it is applied thinly. In order to achieve a defined edge it may help to apply masking tape, roller up to and over the tape and remove tape while Our Peelable coatings Peelable coating is still wet.
If the Our Peelable coating film rips or tears, the flap may be lifted and resealed by applying a fresh wet coat to the underside and resealing. Alternatively, cut away flap and re-apply fresh coating, it will bond to itself.
External Weather Resistance:
Long-term exposure to sunlight will cause premature deterioration and brittleness of the film. Exposure to water after the film is dried will soften the film but it will recover once it dries. Avoid traffic over the wet or while the film is wet. If components are to be stored externally for several weeks we recommend the application of acrylic topcoat which will protect for 12 months and more.
It is critical that Our Peelable coating film is allowed to cure dry. Drying time will vary according to humidity, temperature and weather condition. The evaporation of water will be speeded by air movement and warmth supplied by natural and mechanical means.
Our Peelable coatings is a temporary protective Peelable coating and adhesion is low.
Our Peelable coatings once completely dry are resistant to water and solvent and acts as a mask against sprayed emulsion paints, lacquers, oil or grease and water.
The dry Our Peelable coatings strippable coating film can be easily removed either by hand stripping or other means. Our Peelable coatings are thermoplastic. Do not try to remove in freezing conditions. Our Peelable coatings becomes brittle in freezing condition.
Our Peelable coating is a water-based product and you can clean spray equipment and brushes with water. Do this immediately before peelalbe coating starts to dry.
