In general, we have two classes of paint strippers,
1) EF (Environment friendly) based
2) MC (Methylene Chloride) based

1) Generally, MC (Methylene Chloride) based paint strippers work faster and more effective than EF (Environment friendly) paint strippers.
2) MC based paint strippers are being regulated in some districts and municipalities. Meaning that you will not be allowed to use large quantities of that in a given period of time. This could usually be a concern if you are using about 55 Gallon drum or more per month.
3) EF paint strippers are biodegradable and water soluble.

After applying the product to the surface, you should notice tiny little bubbles forming on the top of the surface. When you see those, you know it's working. The EF 6600-B products are based on SSD technology (Smart Surface Detection), which works by releasing the bond between the coating(s) and the surface.

There are a few reasons why this happened:
. You might have applied too little of the paint stripper. The paint absorbed it all and it stopped working. Remember that you should not be able to see your underlying paint after you have applied the paint remover.
. Your project might have been painted with latex paint overtop of oil paint or vice versa, resulting in bad adhesion between the layers. In that case, the stripper will travel through the first layer or two then stop because it believes it has reached the surface.
. The temperature which you applied the paint stripper is below 70F which causes the EF paint strippers to work very slowly.
In situations like these you will need to scrape that paint that has been lifted and re-apply more paint stripper product.

The correct procedures for using both of these paint strippers require washing (power washing) the derusted steel immediately after the application. At that point the steel is extraordinarily clean so flash rust occurs almost immediately.

By using an airless sprayer, paintbrush or roller, apply the product evenly (an airless sprayer is best), with enough volume so that the AF to be removed is no longer visible. Leave the product on the AF surface until it visibly separates from the substrate. Use manual scraping, vacuum scraping or water pressure washing to remove the AF.

Usually between two to six hours. The longer the product is left on the metal surface (‘dwell time’) the easier its removal will become, provided the product does not dry out. This can occur in direct sunlight or hot, dry weather where you simply re-apply product. Generally the process is faster when the air temperature is warmer. It will take longer for the product to work, the thicker the total antifouling film build. Applying the product in the late afternoon and removing the paint film the next morning works well in most conditions. You don’t need to do anything while the product is working.

You must collect all the paint waste. Place a plastic sheet under the work area. If using a water wash-down process, a disposable filter cloth can be placed over the plastic film to filter out solid AF. When scraping, wipe the paint residue from the scraper into the empty EF 6600 paint stripper plastic pail. At the end of the job, discard the AF waste according to state EPA or local council regulations.

EF paint stripper products work best at temperatures starting at 70F / 15C.
Working with EF paint stripper products at temperatures below 70F / 15C requires longer / increased dwell times.

If EF paint strippers (Brush type) dry out, reapply fresh product. A new coat of SPC product can be used to wet the original coat.

Yes.

When coating layers are completely lifted.
If EF paint stripper (brush type) dry out they are no longer working—reapply fresh product.
When the substrate is reached.

MC and EF paint strippers are ready to use as received. Addition of water will destabilize product making it ineffective.

From a different perspective, all our paint strippers could be divided into two categories:
1) Immersion (or dip tank) type paint stripper.
2) Brush type paint stripperwhich could even be applied using a spray gun.
Immersion (Dip) paint strippers) are always stronger than their brush (spray) type counterparts.
Basically, if the size of the objects you are dealing with is small enough, it is always better to order Immersion (Dip) type of paint strippers. But, if you are dealing with bigger objects such as; building, aircrafts, marine, …, then you will find brush (spray) type paint stripper more suitable.

It is very easy. Just try answering the following questions:
1) Is it practical for you to dip (immerse) your object into a tank of liquid paint strippers?
Yes. Then Immersion type of paint strippers will be the way to go.
No. Then, you have to choose brush type paint strippers.
2) Are you going to use paint stripper on a regular basis (say, at least 20 Gallons or more per month)?
Yes, Then, there is a chance that you will have to use EF paint
strippers.
No. Then, there is a chance that you may be able to use MC paint strippers.
It is hard for us to give a definite answer to this question, because the environmental regulations vary from state to state and country to country.

1) MC 5000 Paint strippers are safe on Steel, Aluminum, Magnesium, and almost any other alloys.
2) EF Paint strippers are safe on Aluminum, Magnesium, and Fiberglass as well as wood and brick.

You should apply a thick layer of paint stripper equaling the thickness of the paint.

One gallon should cover approximately 90-110 sq. ft.

Simply by contacting our experienced technical representative team [info@topchimie.com or 888-331-3371], you can ask for a free sample.
It would be great if you could even supply us with your UPS number to take care of shipping the sample to you. In any event, the sample is free and you will never be billed for that.

1) For MC (Methylene Chloride) based paint stripper - about 20 minutes.
2) For EF (Environmentally Friendly) paint strippers - about 2-3 hours.

Yes, our paint stripper EF 6600 and MC 5000 line of products are specifically manufactured for tough aircraft coating.

ENV 6600 Paint Strippers are environmentally friendly products. Nevertheless, we ask that you treat all stripped paint as hazardous waste and just dispose of it according to your local and national standards.

Switching from methylene chloride to benzyl alcohol paint stripping will decrease a facility's HAP emissions which will decrease the possibility that a facility will meet the HAP emissions threshold for an air permit under 40 CFR 70 and 71. Reducing HAP emissions may also help a facility to comply with the requirements of the National Emission Standards for Hazardous Air Pollutants (NESHAPs) (40 CFR 63).
