    Abstract: Macrocyclic compounds, e.g., ketones, crown ethers, methicones etc., have been found to be effective co-solvents in solvent based adhesives for pipe joining applications. Because of their enhanced solubility with VOC exempt solvents (40 C.F.R. 51.100), the calculated VOC content of the adhesive can be lowered to at least 75% of those established by SCAQMD Rule 116A.
