  • Frozen, lightweight curable sealant
    Patent number: 7645840
    Abstract: A uniformly premixed sealant is extruded into a packaging form and allowed to pressure equilibrate prior to freezing. Upon warming the sealant begins to cure. The storage of the preformed sealant formulation under cold conditions arrests the activity of cure catalysts and accelerators mixed therethrough. The sealant is readily extruded into a preform shape containing a lightweight filler. A release film is provided to avoid contact with the sealant preformed in a shape during application to a substrate.

  • Process of preparing functional fluoropolymers
    Patent number: 7220807
    Abstract: Functional fluoro-monomers are polymerized with an organoborane functional initiator in the presence of oxygen to yield functional fluoropolymers and copolymers to produce functional polymers having functional groups at the beginning of the polymer chain.

  • Frozen, preformed curable seal
    Patent number: 6881462
    Abstract: A uniformly premixed sealant is provided as a frozen preform that upon warming cures in the preform shape. The storage of the preformed sealant formulation under cold conditions arrests the activity of cure catalysts and accelerators mixed therethrough. A release film is provided to avoid contact with the preformed sealant during application to a substrate. The preformed sealant is particularly well suited for use in aerospace applications.

  • Waterless hand cleaner containing natural essential oil
    Publication number: 20030083212
    Abstract: A waterless hand cleaner formulation includes an organic solvent, a quantity of water and a surfactant present to form a gelatinous emulsion. The gelatinous emulsion is loaded with 0.1 to 25 total weight percent of a natural essential oil having topical antimicrobial activity. Oil of oregano is particularly well suited for this application.
