Temporary Protective Strippable coating and Peelable coating For Sign |
|
|
|
|
| |
A strippable coating for temporary masking of acrylics, plastics polystyrene and painted surfaces during paint spraying and vacuum metallising. For temporary protection. |
|
|
|
|
| |
Some means of masking must be used to determine the areas to be covered with leaf. Masking tape could be used, but can be troublesome on the compound curves of a turning. General Chemical's liquid masking material-SignPeel Maskant is available that works well. |
|
|
|
|
| |
Applies as a liquid and dries to form a contour hugging plasic film. Easy to cut and weed and simply strips away after use leaving no residue. Economic and ideal for moulded sign pans. |
|
|
|
|
| |
Water-based, transparent strippable coating used in the decoration of plastic signage. |
|
|
|
|

SignPeel Mask is a unique liquid maskant used in sign face decoration. It is a water-based, water soluble, non-toxic, Earth-friendly spray masking that can be either sprayed, rolled or brushed on, and when allowed to dry, can be cut and peeled for painting. The unique advantages SignPeel offers, coupled with its ease of spraying, peelablility and lasting elasticity, make SignPeel the best product available |

|
|
|
|
| |
|
Results in a reduction of labor costs. |
|
Once cured, it provides an extremely tough, uniform film thickness. |
|
Curing time can be cut considerably with the use heat lamps (100F), circulation of air and other factors. |

Description: |
|
|
| |
Liquid mask may be painted on the turning with a brush, but spraying it with a Critter spray gun at 90 psi works much better. This provides a relatively smooth surface on which layout lines can be accurately drawn. Remember that this product is water-based, and applying a too heavy first coat may cause moisture to migrate into the wood, raising the grain and damaging the pre-finish. A light coat of mask, followed by two or three heavier coats will work well. If the mask is too thin, it will be difficult to remove. If it is too thick, material has been wasted, and it will be more difficult to obtain sharp edges on the leaf. As each coat dries, it will change from white to a transparent blue- color. |

APPLICATION By brush, roller or by standard spray guns, e.g. DeVilbiss JGA or MBC equipped with (a) Pressure feed with FF or FX nozzle and jet with 765 Air Cap: (b) Suction feed with FF or FX (1.8 tip size) nozzle and jet with 306D Air Cap.
|
|
|
|
|

Atomisation pressure 4.05-4.75ATM (60-70psi). A minimum Dry film thickness of 100 microns is recommended. (250 microns wet |
|
|
|
|
| |
Apply to achieve a minimum wet film thickness of 250 microns = 100 microns DFT (dry film thickness). IT IS VERY IMPORTANT TO ACHIEVE AN EVEN DFT OF MIN 100 MICRONS. As anything less may result in the film becoming difficult to remove. |
|
|
|
|
| |
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 BoatPeel Peelable coating is still wet. |

| |
Surface Prepartion: |
|
|
|
|
| |
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). DRYING |

|
| |
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.
|
|
|
|
|
| |
 |
Drying Time: |
|
|
| |
It is critical that 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. |
|
|
|
|
| |
 |
Adhesion: |
|
|
| |
BoatPeel is a temporary protective Peelable coating and adhesion is low.
|
|
|
|
|
| |
 |
Process: |
|
|
| |
Once completely dry is resistant to water and solvent and acts as a mask against sprayed emulsion paints, lacquers, oil or grease and water.
|
|
|
|
|
| |
 |
Removal: |
|
|
| |
The dry strippable coating film can be easily removed either by hand stripping or other means. Peelable coatings are thermoplastic. Do not try to remove in freezing conditions-becomes brittle in freezing condition.
|
|
|
|
|
| |
 |
Clean Up: |
|
|
| |
Is a water-based product and you can clean spray equipment and brushes with water. Do this immediately before peelalbe coating starts to dry.
|
|
|
|
|
| |
