This is a quote from the naked truth magazine by Fred Mueller:

"It doesn't matter what technique you use,stripping paint is hard and costly work. One of the oldest methods of stripping paint is to use heat.

I remember using a blowtorch to literally bubble/soften the paint so that it could be scraped off the surface using sharp edged tools and/or sandpaper (mechanical stripping ) is not only the most labour intensive technique but it wont make Pratt Whitney Canada or any other aerospace customer happy.

Enter chemical paint stripper and environmentally friendly chemical paint stripper, we'd all be environmentally conscious if it didn't cost more money. Right? So, is there and economic upside to the environmental friendly paint strippers? all chemical paint strippers are formulated with a variety of chemical compounds to strip and clean the base surfaces. They're formulated to do a combination of things at the same time.


Paint stripper components depending on the type of coating being stripped, different co-solvent are added to boost the solvency of the primary ingredient. These cosolvents differ according to the target paint type activators increase the penetration rate by disrupting the molecular bonds within the paint film helping to weaken it.

Surfactants help by making the the stripper wetter and increasing the stripper's surface penetrating power. anionic surfactants are used in acidic stripper formulae and cationic or nonionic are used in alkaline stripper formulas.

Paint strippers that contain surfactants make the best brush cleaners. Thickeners are use to make a gel of the liquid paint stripper. These type of formulae help the mixture adhere to vertical and "ceiling"surfaces and reduce the evaporation rate of the solvents.

Which dramatically prolongs the time the solvents can work at penetrating the paint. Corrosion inhibitors protect the underlying substrate and the "tin can" the paint stripper comes in from by neutralizing acids that from from the composition products created as the stripper ages.

Chelating agents are used to suppress/"remove" metal ions present in the stripping solution from the stripper solution/stripping reaction. Loose metal ions could reduce the efficiency of the strippers's components and could contribute to surface stains. Colorants are often added to make the stripper stand out from the competitors. but this marketing ploy has a practical up-side for the customer as it makes it easier to see where the paint stripper has been applied."

Case Studies:

Outside tanks at the Brookhaven National Laboratory's RHIC (Realativistic heavy Ion Collider) facility in Upton, NY, needed to be repainted. Research into the costs of conventional paint stripping found it to be economically impractical. one of the supervisors for plant engineering had had about proprietary hydrogen peroxide stripper distributed by PPG and though it was worth a try. the process involved spraying on a proprietary hydrogen peroxide

mixture, waiting 12-24 hours, then using a broom squeegee to wipe off the peeling paint layers, and them power washing remove any lingering paint flakes. the use of the hydrogen peroxide paint stripper is estimated to have saved BNL exceed of $100.000 and at least 50 per cent of labour and wasted disposal costs. Molecular Tech Coatings Inc., Maple Ridge BC, has developed a new general environmentally friendly paint stripper that works without the usual suspects (solvents). The formulation contains no Methylene Chloride, no formic acid, nor carbonic acid, and no N-MP (Nmethylpyrrolidone). the ingredients used in this formulation comply with the US EPA rules on emissions. It's non toxic and safe enough to ship with UPS, Fed-X and Canada post." the product is very economical because you use less of the product to strip more paint." And since the paint stripper is not as volatile compare to the old stripper, less

does more stripping. the lower toxicity of today's paint together with the non toxic paint stripper make it (after testing) possible to landfill the waste products, adding that these stripper are easier on the employee who's applying the stripper and removing the paint because they need less personal protective equipment. Because worker safety is so important, more and more regulatory bodies across North America are banning methylene chloride containing paint stripper. When you look at the results from workers in automotive body shops' blood tests, will it can be pretty scary, even with the proper PPE. So in answer to the question "can you achieve cost savings with green stripping technologies, the answer is YES. The advantage to going green- lower VOCs, less PPE, safer products for shipping, reduced disposal costs - are good reasons for your company and your employees.
