PUR-Strip 100, 200
SAFETY SOAKING SOLVENTS

The PUR-Strip products are engineered solvent blends that were developed for use in removing cured urethane residues from various types of polyurethane processing equipment. PUR-Strip 100 and PUR-Strip 200 are nonchlorinated, nonflammable (per DOT), non-carcinogenic, non-ozone depleting solvents designed to replace solvents such as methylene chloride, acetone, MEK, and 1,1,1-trichloroethane. They have the benefits of being safer in the workplace and friendlier to the environment. Many alternative soaking solvents used in this application are based on solvents such as n-methyl pyrrolidone (NMP), dibasic ester (DBE), and dimethyl formamide (DMF). The PUR-Strip products are based on completely different chemistry. This new chemistry, when combined with various glycol ethers and alkalinity sources, produce very effective polyurethane removers that are safe to handle.

APPLICATIONS:
1. The PUR-Strippers are especially effective for removal of cured urethanes from processing equipment. 
2. They are effective in removal of all types of urethanes:  flexible, rigid, elastomer, or moulded; inks or paints. Effective for both MDI and TDI esters and ethers.
3. The PUR-Strip solvents are distinguishable by their aggressiveness and method of removal. Each product works in two ways – 1) by breaking the bond between the polyurethane and the substrate and removing the contaminant in small pieces and 2) by dissolving the polyurethane.
