Temporary Protective Peelable Coatings For Industrial Processes |
|
|
|
|
| |
Temporary Protective water resistant Peelable coating For Industrial Processes: |
|
| |
some of the customer's current processes:
1.I need a product that can be sprayed on aluminum parts and then machined. I use coolant now to wash away chips, sometimes the chips scratch the surface of the part I am machining. This scraps the part I am machining. I would like to have a water based product that I could spray on, let dry, then cover with oil. If possible I would like to use your product to lubricate my tool, and not cover with oil.
2. Peelable product required to protect magnesium ingot once installed and steel surface around ingot to be painted without paint getting on ingot - coating to be peeled away after painting Current Chemical Used and the Manufacturing
3. I must borrow another company's brand new 125' aerial manlift for my spray painting job. Naturally they are very expensive and they wish for me to not get any paint on it. It looks nice and I don't want to get any paint on it or the man basket. Can you Help Me !!!!!Do you have a coating that I can apply and simply rinse off afterward....The paint will not be very concentrated as to block any water getting to a protective film...This is the first time I've ever heard of something like this...
4. I called last week looking for a strippable coating and you asked me to detail the process we go through in-order for you to make a recommendation. The process starts with a steel blank with the top side covered with a copper foil.
Electroplating tape is placed on the bottom of the steel blank.
Any exposed steel that is not covered with the tape and or copper foil is covered with PEELABLE COATING
We let coating dry over night. The steel is then exposed to Ferric Chloride etching solution at 132 degrees F. with a Baume reading of 42 for 90 seconds. Then goes through 2 cold water baths.
Then placed in a hot water solution that softens the tape and Peelable coating.
Last cleaning is a 150 degree F Ultrasonic cleaning of 9 parts water to 1 part chemical cleaner to 1/2 part Advantage Alkaline cleaner #99a for 2 minutes. Last step is to rinse with water.
5. I've been looking for a Peelable coating product, found you, and have a couple of questions I hope you can answer.
I need to coat items made from aluminum and copper plate that are roughly 24 by 10 inches, 1/8th to 1/4 inch thick. The coating is to protect the items from handling and abrasion while on display at their point of sale. The coating must be clear to show the finished metal surface, and able to be applied by rolling or brushing.
From what I can tell, both your AquaShield 4670 and Stripaway 4580 seem like they would work. Can you please recommend which product would be best for my application, or suggest an alternative? Also, the dried coating is 1-3 mils. Can a second coat be applied for a thicker finish? Thank you for your help.
6.I am looking for a temporary coating for carbon steel and stainless steel weld joints on tanks. (The tanks are used for
transporting radioactive materials.) The coating is removed once a year in order to inspect the welds, then recoated. The coating should have good exterior durability and resistance to corrosion. Do you think that one of your strippable coatings might work in this application? Drying time is not an issue. The tanks are currently coated with a 2K polyurethane system. The welds are masked and coated later. Drying time can be whatever is required by the coating. Solventborne is acceptable. My main concern is that the coating has the required durability (one year maximum). I realize it's somewhat contradictory to expect good performance, which requires good adhesion, but have the coating easily removable.
Removal with alkaline solution would be acceptable also. Answer: Use our Boothcoat 5201
7.I am searching for an acid resistant coating that can be applied via brush in our manufacturing process to mask specific regions on our product during chemical etch. After the etch process we then want to remove the coating COMPLETELY leaving absolutely no trace residue. (A post process solvent wipe to remove any material would be acceptable.) The base materials can be:
1. SS304 or
2.Rhenium or
3. Tungsten or
4. Molybdenum.
The acids that the material will have to resist are dependent on the base material and may involve a secondary exposure via immersion in one or more of the below acids:
1. Hydrogen peroxide (50%) plus Ammonium hydroxide (50%)
2. Nitric Acid (50%)
3. Hydrofluoric Acid (30%) plus Nitric Acid (20%)
4. Hydrochloric Acid (50%)
5. Hydrochloric Acid (75%) plus Nitric Acid (25%)
6. Sulfuric Acid (15%)
7. Sodium Hypocloride (100%) The immersion times in these acids can range from 10 to 30 minutes.
The temperatures at which these processes can be performed are: 1. Room Temp or
2. 100°C or
3. 200°C
Can you provide me with a product that meets these requirements? Thank you. Sincerely,
Answer : Coscoat 4300 is a solvent based product formulated for brushing with maximum film built. This product was tested overnight at 100C in sulfuric, phosphoric, hydrochloric and nitric acids. Coscoat 4300 applied to 2 1/2 mils of dry film protected the metal substrate and peeled with ease. The product was tried over bare aluminum, cold rolled steel, stainless steel and lead. |

Main Advantages: |
|
|
|
|
|
|
|
| |
Offers cost-effective protection during construction. A tough weather-resistant film, withstands foot traffic, scratching and solvents overspray. It removes cleanly without leaving residue.
|
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. |
|
Easily removed...peels off in sheets which eliminates messy hand scrapping |
|
Safe...non flammable |

Description: |
|
|
|
General Chemical's strippable coatings dries to form a contour-hugging skin-tight protective film on various surfaces to protect from damage caused by staining, surface scratches from air hoses, electrical cables and hand tools. This prevents costly clean-up during and upon completion of construction.
The General Chemical peelalbe coating is a water borne non-toxic and non-hazardous product which is applied by lamb’s wool roller. It peels away cleanly leaving no residue and will not damage plastics or painted surfaces.
General Chemical strippable coating is also used to protect heavy traffic areas and sensitive surfaces against staining and abrasion during construction, storage and transport. Simply roll on and peel off on completion. The tough film is weather-resistant, UV and solvent resistant. |

|
 |
Application: |
|
|
|
|
|
|
|
|
|
|
|
|
Standard air assisted, or airless spray equipment, Brush or Roller (Use lambs wool roller).
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.
The strippable coating should be applied at around 150 microns min. DFT or heavier over rough surfaces or areas of heavy foot traffic. |

|
|
|
|
 |
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. |
|
|
|
