Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diamines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.

Abstract: A syringe (10) includes a tube (12) defining a chamber (16) with a dispensing opening (18). A plunger (20) is slidably mounted in the tube and is initially positioned at the end (24) of the chamber opposite the dispensing opening. A dasher (26) having an opening (34) is positioned within the chamber at an intermediate point. A cylindrical barrier (40) is detachably secured to the dasher (26). Thus, with the barrier secured to the dasher, the barrier and dasher sealingly engages the tube dividing it into two subchambers (44, 46). An elongated rod (52) extends through openings (54, 56) in the plunger and the barrier and is secured to the dasher. Rotation of the rod detaches the barrier from the dasher establishing communication between the subchambers. A locking sleeve (62) frictionally secures the rod and the plunger together when the rod is moved to a retracted position (FIG. 4). Furthermore, optionally the rod is hollow (FIG. 9) and defines a third subchamber (80) containing a third liquid.
