Solvent-containing paint strippers

Also known as DCM or dichloromethane. Often used as an adhesive solvent for acrylics. Pure DCM can be found in craft stores. DCM must be distilled first from all non-flammable paint strippers beforehand (they contain a paste that holds several unwanted substances.) The paint stripper may also contain methanol (most marine grade paint strippers are 80-90% DCM. Methanol is also an organic solvent. DCM distills at 47° C or 116° F. Pure DCM is best. May cause cancer and blindness. Take necessary precautions. Methylene chloride sinks to the bottom of the jar.

Paint stripper formulations containing DBE solvents have replaced many of the methylene chloride-based strippers. The DBE can be used alone or with cosolvents like N-methyl-2-pyrrolidone (NMP) and a hydrocarbon (Table ll.lO) [3]. Formulations A and B in the table are effective for many paints. A blend of 60 wt% DBE and 40 wt% NMP or a blend of 60 wt% DBE and 40 wt% ethyl-3-ethoxypropionate can be used in a hot dip operation. The preferred dibasic esters in these blends are DBE-2 and DBE-3 because of their low vapor pressures. 

Solvent Handbook Database System (SHDS) - SHDS is a database providing access to environmental and safety information on solvents used in maintenance facilities and paint strippers. SHDS contains empirical data from laboratory testing. 

Vapours on construction sites may arise from a number of sources. Many paint strippers used to contain benzene which has an insidious toxic effect. The result of the draft regulations currently in preparation will be to ban its use as a solvent, but many other solvents are used in paints, adhesives and surface treatments which may give rise to risks to health.

In addition to tobacco smokers, individuals who have had previous exposure to materials containing methylene chloride, such as degreasers, solvents, paint removers, and furniture strippers, are at greater risk because of an existing body burden of carbon monoxide. Approximately one-fourth to one-third of inhaled methylene chloride vapor is metabolized in the liver to carbon monoxide. In addition, methylene chloride is readily stored in body tissue. This stored material is released over time and results in elevated levels of carbon monoxide for extended periods, in some cases more than twice as long as compared with direct carbon monoxide inhalation. 

Based on these tests, we conclude that chemical paint stripping is a practical and safe method of removing lead paint providing the stripper does not contain such volatile solvents as methylene dichloride or other materials such as...
