6. Spray apply 20 – 25 wet mils minimum.
7. Dry to cut graphics at 70oF (20oC) 50% R.H. – 12 hours. Ready to spray.
SCHEDULE: 12 – 24 hours at 65–95oF (18-35oC). SignPeel may be force dried at 100-110 oF.
Increasing air flow speeds up dry time.
SUITABLE SURFACES: Acrylic, impact modified acrylic, ABS, CAB, polycarbonate, styrene and most flexible and rigid vinyl.
Paper masking may leave a latex residue on the sheet. This residue can result in poor wetting of the paint on the surface of the sheet and poor paint adhesion.Clean plastic with mixture of isopropyl alcohol, or T-4000 and water (1:1 by volume).
Paint Removal: Spray and screen paints can be removed using General Chemical’s Aquastrip 5570 Paint removers. To reduce the chances of crazing the surface of the sheet, minimize the amount of time ACRYLITE SG sheet is in contact with these solvents. Even with the complete removal of paint from the surface of the sheet, a phenomenon referred to as “ghosting” often occurs. A hazy outline of the original images may remain and become visible upon application of new paint.
Painting techniques typically used with acrylic and polycarbonate sheet can be used with ACRYLITE SG sheet.
Repair: If the dry 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.
It is possible to get a 3 mil tack free dry coating film in less than one hour drying in air at ambient temperature. For maximum tensile strength , 12 hour drying time is better. Blowing air past the surface of the wet film, drying time can be shortened. Heated air up to temperature of 115f can also help in drying time. Mask cures upon water evaporation.
Dry time is dependent upon temperature, humidity, air movement and thickness of the coating. Curing may be accelerated by forced dry air up to 100 degrees Fahrenheit. Force dry coatings can cure in less than 10 minutes. Most coatings without assist will dry in a few hours. It is imperative that Liquid Mask be thoroughly cured and dry, before an attempt is made to peel the coating from the substrate. Cured coating is transparent throughout. Cured Mask is water resistant. Surfaces coated with Mask can be water mopped.
Application by roller might require a few coats. Thick coating peels in one large continuous sheet. Thin coatings will break in areas of coating weakness. Mask is water based for safe use and easy water clean up. Dry coatings are water resistant. When applying Mask use the same protection as used while applying paint.
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.
Cost Effective: SignPeel Mask is the most competitively price product of its kind on the market. Our masks deliver the best value with ease of application, performance and clean up.
General Chemical has a complete line of Peelable Masks to meet your challenging requirement. If we do not have something to meet your specific requirement, than we will develop it by working with you to meet that need for strippable coating.
