Patent ID: 6852684

Claim:
A composition comprising: a.) about 55 to about 75 weight percent trans-1,2-dichloroethylene; and b.) about 15 weight percent or less of at least one solvent selected from the group consisting of: i.) oxygen-containing solvents selected from the group consisting of alcohols, ketones, esters, siloxanes, and ethers; and ii.) hydrocarbon solvents selected from the group consisting of those represented by C t H 2t+2 and C t H 2t , wherein t is from 4 to 12; and c.) about 20 to about 45 weight percent of at least one i.) hydrofluorocarbon inerting agents selected from the group consisting of those represented by the formula C x H y F (2x+2−y) , wherein x is from 3 to 8, y is from 1 to 4, the mole ratio of F/H in the hydrofluorocarbon inerting agent is greater than 1.6, and wherein when the inerting agent is hydrofluorocarbon the weight ratio of hydrofluorocarbon inerting agent to solvent is at least about 1.5; ii.) hydrochlorofluorocarbon inerting agents selected from the group consisting of those represented by the formulae C 2 HCl 2 F 3 and C 2 HClF 4 , and wherein when the inerting agent is hydrochlorofluorocarbon the weight ratio of hydrochlorofluorocarbon inerting agent to solvent is at least about 2, wherein said composition is non-flammable by Flame Extension Test ASTM D-3065 and Flash Point-Tag Closed Cup Test ASTM D-56-82, and said composition has a Kauri Butanol value of at least about 40 by ASTM 1133-94.
