Paint and Metal Stripping (Chemical Stripping)
RIE offers paint and metal stripping services, as part of a complete package of coating services.
Chemical paint stripping, or industrial paint stripping, is designed to remove paint, finishes, and coatings while also cleaning the underlying surface in a process where the chemical bonds of paint are broken down (caustic chemical paint strippers) or the bond between the paint and surface is weakened (solvent chemical paint strippers).
The cold strippers, although the most expensive stripping baths, enjoy the greatest popularity.
They possess the following desirable properties:
1. Rapidity of action
2. High flash point
3. Low inflammability
4. Minimum of corrosion
5. Work is left clean and ready for refinishing
Cold strippers are generally a blend of chlorinated solvents, methylene chloride or ethylene dichloride, methanol, ammonia or-acetic or formic acid, and any number of additional solvents that may be needed for any particular coating.
Hot Solvent Emulsion Strippers
Hot solvent emulsion strippers, based primarily upon phenol or phenolic derivatives and a suitable emulsifier, have been found most advantageous in the stripping of alkyd, melamine, phenolic, epoxy and urea type coatings. They are especially practicable for large production stripping where speed and efficiency are vital to make the stripping operation economically feasible. On a dollar to dollar basis, a much greater value is gotten from the hot emulsion stripper than from any other type of stripper on the market today.
When used as a soak, the emulsion generally contains 3 parts of water to 1 part of stripping concentrate. In a spray stripping operation the concentrate can be diluted 10 to 1. When used as directed by the manufacturer at the proper temperature and in a steam heated tank, there is little fire hazard and the loss due to evaporation is’ small. The pH of these materials is such that coatings can be stripped from zinc, aluminum and brass without attacking the metal.
